The cool temperate woodland is characterized by

spares undergrowth and broad-leaved deciduous trees Respuesta correcta

very sparse vegetation of xerophytic plants

wiry grass and shrub

rolling grassland that are treeless

trees with leaves appearing brown throughout the year

Detalles de la respuesta

The cool temperate woodland is characterized by sparse undergrowth and broad-leaved deciduous trees. This means that there is not a lot of vegetation beneath the canopy of trees, and the trees themselves are deciduous, meaning they lose their leaves in the winter. The sparse undergrowth allows for more light to reach the forest floor, which can encourage the growth of herbaceous plants and wildflowers. This type of woodland is typically found in regions with a temperate climate, characterized by moderate temperatures and precipitation throughout the year.

When you observe the wind vane, the head of the arrow shows the

speed of the wind

direction to which the wind is blowing Respuesta correcta

duration of the wind

weight of the wind

direction from which the wind is blowing

Detalles de la respuesta

When you observe the wind vane, the head of the arrow shows the direction from which the wind is blowing. The wind vane is an instrument used to measure the direction of the wind. It consists of an arrow-like object mounted on a vertical rod, which freely rotates about the rod. The arrow has a larger surface area on one end than the other, causing it to point in the direction from which the wind is coming. The head of the arrow points to the direction from which the wind is blowing while the tail of the arrow is aligned with the opposite direction, giving an indication of the wind's direction.

Cities are not imporatant as rural areas

Rural areas are more productive than cities

Cities can exist without the rural areas

Cities and rural areas depend on each other Respuesta correcta

Rural areas exist only to serve the cities

Detalles de la respuesta

The correct option is: "Cities and rural areas depend on each other." Urban areas and rural areas have a symbiotic relationship where they depend on each other. Urban areas depend on the rural areas for agricultural products, raw materials, and other resources, while the rural areas depend on the urban areas for manufacturing, trade, and other economic activities. The relationship between urban and rural areas is essential for the economic, social, and cultural development of a country.

The Red Sea has a higher degree of salinity than the Mediterranean Sea because the former

is smaller in size than the latter

is located in a rift valley while the letter is located in a geosyncline

receives a smaller amount of fresh water than the latter Respuesta correcta

is linked with the Indian Ocean while the later is linked with the Atlantic

is nearer a hot desert than the latter

Detalles de la respuesta

The correct option is: "receives a smaller amount of fresh water than the latter." The salinity of a body of water is determined by the amount of salt (or other dissolved solids) that is present in the water. In general, the more salt that is present in the water, the higher the salinity will be. The Red Sea and the Mediterranean Sea are both bodies of saltwater. However, the Red Sea is known to have a higher degree of salinity than the Mediterranean Sea. This is because the Red Sea receives a smaller amount of fresh water than the Mediterranean Sea. The Mediterranean Sea is connected to the Atlantic Ocean by the Strait of Gibraltar. This connection allows for a continuous flow of water into the Mediterranean Sea. The Red Sea, on the other hand, is located in a hot and arid region of the world, and it receives a much smaller amount of fresh water from rivers and streams. The lack of fresh water input into the Red Sea means that there is less dilution of the salt that is already present in the water. This results in a higher degree of salinity in the Red Sea as compared to the Mediterranean Sea.

The concept of environmental balance can be taken to mean that an alteration in one of the components of the ecosystem may likely result in the

minimisation of the processes within the system

reversal of the processes within the system Respuesta correcta

acceleration of the processes within the system

stabilization of the processes within the system

stopping of the processes within the system

Detalles de la respuesta

The concept of environmental balance means that an ecosystem functions best when all its components are in a state of harmony and balance. This means that each component, such as plants, animals, and microorganisms, plays a role in maintaining the health of the ecosystem. When one component is altered, it can have a ripple effect on other components, potentially leading to negative consequences. For example, if there is a decline in the population of a certain plant species, it may affect the food supply of animals that depend on it, which in turn may affect predators that depend on those animals. This could result in a cascade of changes that ultimately disrupt the balance of the ecosystem. Therefore, altering one component of an ecosystem can result in the acceleration, minimization, or even reversal of processes within the system, and it is important to maintain a state of balance in order to stabilize the processes within the system.

Detalles de la respuesta

The local winds mentioned in the question are Sirocco, Leveene, Mistral, and Bora. Among these winds, Sirocco is a hot wind that originates from the Sahara desert and blows across the Mediterranean Sea towards Europe. Leveene, Mistral, and Bora are not hot winds, as they originate from cold regions and bring cold air with them. Leveene blows from the land towards the sea in coastal areas, Mistral blows from the Alps towards the Mediterranean Sea, and Bora blows from the east coast of the Adriatic Sea towards the west. Therefore, the correct answer is (a) l and ll only.

Which of the following statements is correct about the Sokoto plains?

It is not an area of inland drainage Respuesta correcta

it lies in the middle of the country and borders the Rivers Benue and Niger

it is a pear shaped upland area

it consists of the basement complex rocks

it is dissected by rift valleys and plateaus

Detalles de la respuesta

The correct statement about the Sokoto plains is that it is not an area of inland drainage. The Sokoto plains are a large expanse of low-lying flat land in northwestern Nigeria that is drained by the Sokoto River and its tributaries, including the Rima River. This means that the area is not an inland drainage area, as the water from the rivers flows outwards towards the Atlantic Ocean. The other statements are incorrect. The Sokoto plains do not lie in the middle of the country nor do they border the Rivers Benue and Niger. They are not a pear-shaped upland area, as they are actually low-lying plains. They also do not consist of the basement complex rocks, which are found in other parts of Nigeria. Finally, the Sokoto plains are not dissected by rift valleys and plateaus, as they are relatively flat and do not have major topographical features.

The rapid exhaustion of non-renewable natural resources may least be aided by one of the following which is it?

Increased urbanisation

Reckless exploitation

Inadequate technology Respuesta correcta

Natural disaster

Excessive demand

Detalles de la respuesta

The rapid exhaustion of non-renewable natural resources may least be aided by inadequate technology. This is because inadequate technology means that natural resources are being used inefficiently and wastefully, which can lead to their rapid depletion. On the other hand, increased urbanization, reckless exploitation, excessive demand, and natural disasters can all contribute to the rapid exhaustion of non-renewable resources. Increased urbanization can lead to increased demand for resources and the destruction of natural habitats. Reckless exploitation involves using resources without regard for their long-term availability or impact on the environment. Excessive demand means that resources are being used at a rate that exceeds their natural replenishment rate. Natural disasters can cause widespread damage and destruction to natural resources, which can take years to recover from. Therefore, to address the rapid exhaustion of non-renewable resources, it is essential to develop and implement appropriate technologies that promote their efficient and sustainable use.

Detalles de la respuesta

Crude oil from Nigeria is transported to Europe through the "South-Atlantic" sea route. This route runs from the Niger Delta region of Nigeria, through the Gulf of Guinea, and across the South Atlantic Ocean to the refineries in Europe. The South-Atlantic sea route is one of the major shipping routes for crude oil transportation, as Nigeria is one of the largest oil-producing countries in Africa. The oil is transported in large tankers, which are specially designed to carry liquid cargo, and they can travel long distances across the open ocean. The other sea routes listed do not connect Nigeria to Europe. The North-Atlantic route runs between North America and Europe, the Trans-Pacific route connects Asia and North America, the Far-East route connects Asia with the western Pacific and Indian Ocean, and the Trans-Indian route connects the Indian Ocean and the western Pacific.

The volcanic plateau among the given options is "Deccan". A volcanic plateau is a large, flat, and elevated landform that is formed from the accumulation of volcanic material over time. Deccan plateau is located in India and is one of the largest volcanic plateaus in the world, covering an area of over 500,000 square kilometers. The Deccan plateau was formed by a series of volcanic eruptions that occurred millions of years ago. The lava flows from these eruptions spread out over a large area, and over time, they cooled and solidified, forming a thick layer of basaltic rock. The plateau is also characterized by many volcanic features, such as cones, vents, and fissures. The other options listed are not volcanic plateaus. Kukuruku is not a known geological feature, Terra Rosa is a type of soil, Graben is a type of geological structure, and Atlas is a mountain range.

Interdependence within the ecosystem can best be interpreted to mean that components of the ecosystem

prey on one another

harm one another

regulate one another

interact with one another Respuesta correcta

create one another

Detalles de la respuesta

Interdependence within the ecosystem means that the different components of the ecosystem interact with one another. They depend on one another for survival, and changes in one component can have an effect on other components. For example, plants and animals depend on each other for food, shelter and pollination. Plants absorb carbon dioxide and release oxygen, while animals breathe in oxygen and release carbon dioxide. Decomposers such as bacteria and fungi break down dead organic matter, and release nutrients back into the soil, which are taken up by plants. This interaction between components creates a balance in the ecosystem, which helps to regulate the population of different organisms and maintain the health of the ecosystem as a whole.

physical factor of rainfall

movement of people from one place to another

occurrence of earthquakes in certain areas Respuesta correcta

Detalles de la respuesta

The factor that least explains the pattern of population distribution in Nigeria is the occurrence of earthquakes in certain areas. This is because earthquakes are not a common occurrence in Nigeria, and even when they occur, they are usually mild and do not cause significant damage to human settlements. Therefore, earthquakes cannot have a significant impact on the distribution of population in Nigeria. On the other hand, the other factors listed have played a significant role in shaping the population distribution in Nigeria. Arab slave raiding, for instance, led to the movement of people away from certain areas. The stability of government of the old kingdoms attracted people to settle in those areas, while physical factors such as rainfall influenced where people could engage in agriculture and other economic activities. The movement of people from one place to another has also contributed to population distribution patterns in Nigeria.

organically formed sedimentary rocks

volcanic rocks

mechanically formed sedimentary rocks Respuesta correcta

Detalles de la respuesta

The given description is a characteristic of "mechanically formed sedimentary rocks". These rocks are formed from the accumulation of sediments or fragments of other rocks that have been mechanically weathered and eroded, and then transported by water, wind, or ice to a new location. The sediments are then deposited and compacted, and often cemented together by minerals such as silica, calcium carbonate, or iron oxide, forming a solid rock. Examples of mechanically formed sedimentary rocks include sandstone, shale, and conglomerate, which are made up of grains of sand, clay, and pebbles, respectively. Metamorphic rocks are formed from existing rocks that have been subjected to high temperatures and pressures, causing them to change in composition and texture. Plutonic rocks are igneous rocks that solidified from magma deep within the Earth's crust. Organically formed sedimentary rocks are formed from the accumulation of organic matter such as shells or plant material. Volcanic rocks are igneous rocks that solidified from lava or magma on the Earth's surface.
