Question 5 Report
Eluviation is the process by which?
Answer Details
Eluviation is the process by which soluble substances are removed from the upper layers of the soil. Essentially, it involves the movement of water through the soil, which carries dissolved materials with it as it percolates down through the layers of the soil. As the water moves through the soil, it tends to pick up and transport soluble substances such as minerals and organic compounds. These substances are then carried down through the soil layers and may eventually end up in lower layers or be carried away by groundwater. This process can have important effects on the chemical properties of the soil, as it can impact the availability of nutrients for plants and other organisms that depend on the soil ecosystem.
Question 6 Report
Under which of the following climates would you expect physical weathering to be normally most active?
Answer Details
Under the hot desert climate, you would expect physical weathering to be most active. Physical weathering is the process by which rocks are broken down into smaller pieces without a change in their chemical composition. This process is influenced by factors such as temperature, pressure, and the presence of water. In hot desert climates, temperatures are high during the day and low at night, and there is limited rainfall. The high temperatures cause rocks to expand during the day and contract at night, which can lead to the formation of cracks and fractures. The limited rainfall means that there is little chemical weathering taking place, so the rocks are more susceptible to physical weathering. In contrast, savannah, warm temperate, and equatorial climates tend to have more rainfall and less temperature fluctuation, which can lead to more chemical weathering and less physical weathering. Therefore, based on the given options, the hot desert climate would be the best fit for the question of which climate would typically experience the most physical weathering.

Question 16 Report
Which of the following landforms results from wind deposition?
Answer Details
The landform that results from wind deposition is a sand dune, specifically the type of dune known as a "barchan." Barchan dunes are crescent-shaped sand dunes that form in areas with limited vegetation and a steady wind direction. The wind blows sand particles up the windward side of the dune, and then they fall down the leeward side, forming a gentle slope. Over time, this process creates the characteristic crescent shape of the barchan dune. The other options listed are all landforms that can result from other geological processes. A bajada is a broad slope of alluvial material formed by the merging of several coalescing alluvial fans, which are formed by water deposition. A fan is also an alluvial deposit created by water flow, typically in a mountainous area. A playa is a dry lake bed that can form in a desert environment due to a combination of wind erosion and evaporation.
Question 18 Report
The flow diagram is the most appropriate mapping technique to use in showing?
Answer Details
The flow diagram is a mapping technique that visualizes the flow of data or objects through a system or process. It is most appropriate to use when showing the movements or transitions of items or information. Out of the given options, the most suitable use of a flow diagram would be to show the movements of migrants between states. A flow diagram can help represent the migration patterns by illustrating the movement of people from one state to another. The flow diagram can also show the direction and magnitude of the migration and help identify any trends or patterns in the data. Although a flow diagram can be used to represent wind directions at different stations, it may not be the most appropriate mapping technique. A wind rose diagram, which is a circular diagram showing the distribution of wind directions and speeds at a particular location, may be a better option. Similarly, a flow diagram may not be the best option to represent the proportion of birds' populations in each state or man/land ratio in each state. A bar graph or a pie chart could be more effective for visualizing this type of data.
Question 19 Report
A poorly-drained soil is characterized by greyish colour and?
Answer Details
A poorly-drained soil is characterized by a greyish color due to the lack of oxygen in the soil. When there is not enough oxygen in the soil, it can become waterlogged and lead to poor drainage. This condition is not suitable for many plants because they need a good supply of oxygen to their roots to grow and thrive. The greyish color of the soil is caused by the accumulation of iron sulfides, which are formed in the absence of oxygen. This condition is often seen in wetland or swampy areas, where water cannot drain away easily. Therefore, the correct answer is not high acidity, abundant ferric oxides, or excessive drainage but rather poor aeration due to the lack of oxygen in the soil caused by poor drainage.
Question 21 Report
On maps, places with equal sunshine duration are joined by?
Answer Details
On maps, places with equal sunshine duration are joined by isohels. Isohels are lines drawn on a map to connect points that receive an equal amount of sunshine duration in a given time period, such as a day or a year. These lines are often used on weather maps to help show the distribution of sunlight across a particular region. Isohyets are used to connect places with equal rainfall amounts, isotherms join places with equal temperature, and isonephs join places with equal cloud cover. Therefore, the best fit for the given description is isohels, as it refers specifically to the joining of places with equal sunshine duration.

Question 27 Report
In which of the the following countries is land reclaimed from the sea intensively used for cultivation?
Answer Details
The country where land reclaimed from the sea is intensively used for cultivation is Holland (also known as the Netherlands). The Dutch have a long history of reclaiming land from the sea, which has allowed them to expand their agricultural and urban areas. This process involves building dikes and drainage systems to drain the water from the land, making it suitable for farming or other uses. The Dutch have been doing this for centuries and have become experts in managing their reclaimed land, which they call "polders". Today, much of the Netherlands' highly productive farmland is located on reclaimed land. Other countries, such as Belgium, England, and Finland, also have reclaimed land, but it is not used for cultivation as extensively as it is in the Netherlands.

Question 45 Report
The rotation of the earth on its axis?
Answer Details
The rotation of the earth on its axis causes day and night. The earth rotates on its axis, which is an imaginary line passing through its center, once every 24 hours. As the earth rotates, different parts of it face towards or away from the sun, which causes day and night to occur. The side of the earth facing towards the sun experiences daylight, while the side facing away from the sun experiences darkness, creating night. The earth's rotation also affects the apparent movement of the sun and stars across the sky. The varying lengths of day and night and the change of seasons are both caused by other factors, such as the tilt of the earth's axis and its orbit around the sun. Delimiting the tropics refers to defining the geographical boundaries of the tropics, which are regions of the earth surrounding the equator that experience warm temperatures and high humidity. Therefore, the best fit for the given question is that the rotation of the earth on its axis causes day and night to occur.
Question 48 Report
The direction of flow of ocean currents is determined mainly by the
Answer Details
The direction of flow of ocean currents is mainly determined by the prevailing winds and the rotation of the earth. The rotation of the earth causes a phenomenon known as the Coriolis effect, which deflects moving objects, such as air and water, to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Prevailing winds, which are caused by differences in temperature and air pressure, create surface currents that are deflected by the Coriolis effect, resulting in the formation of large, circular ocean currents. The shape of the continents also plays a role in determining the direction of these currents, as they can act as barriers or channels that affect the flow of water. The temperature of the continental interior can also influence the direction of currents, as warm water tends to flow towards colder water. However, the depth of the ocean and the amount of fresh water inflow are not significant factors in determining the direction of ocean currents.
