Whats is the birth rate of a country with total population of 160 million and registered births of 4 million in a given year?
Detalhes da Resposta
The birth rate of a country is the number of live births per 1,000 people in a population in a given year. To calculate the birth rate, we divide the number of registered births by the total population and multiply by 1,000. In this case, the total population is 160 million, and the number of registered births is 4 million. Birth rate = (Number of registered births / Total population) x 1,000 Birth rate = (4,000,000 / 160,000,000) x 1,000 Birth rate = 25 per 1,000 Therefore, the birth rate of the country is 2.5%.

Pergunta 8 Relatório
The major primary activity in a coniferous forest is?
Detalhes da Resposta
The major primary activity in a coniferous forest is lumbering. Coniferous forests, also known as taiga or boreal forests, are dominated by cone-bearing trees such as pine, spruce, and fir. These trees are a valuable source of timber, which is used for a wide range of purposes including construction, furniture making, and paper manufacturing. Lumbering involves the cutting and harvesting of trees for commercial use. In a coniferous forest, this typically involves clearcutting, which is the removal of all trees in a given area. Once the trees have been felled, they are typically transported to sawmills for processing into lumber. While lumbering is the primary activity in a coniferous forest, other activities such as hunting and fishing may also take place. However, these are generally secondary activities that are pursued by local communities or recreational users, rather than commercial enterprises. Overall, the value of coniferous forests as a source of timber has made lumbering the dominant economic activity in many areas, particularly in regions where other primary activities such as agriculture or mining are less feasible. However, sustainable management practices are needed to ensure that these forests continue to provide valuable resources while also preserving their ecological and cultural significance.

The temperature at which condensation occurs when air is saturated is the?
Detalhes da Resposta
The temperature at which condensation occurs when air is saturated is the dew point. When air is fully saturated, it can no longer hold water vapor and some of the water vapor turns into liquid droplets. This process is known as condensation. The temperature at which this occurs is called the dew point temperature. It is the temperature to which air must be cooled, at constant pressure, for it to become saturated and for condensation to occur. At the dew point temperature, the air becomes saturated with water vapor and any additional cooling will result in the formation of dew, fog, or frost.

Pergunta 36 Relatório
Which of the following is a product of volcanicity?
Detalhes da Resposta
A plug dome is a product of volcanicity. It is formed when magma that is rich in gas is squeezed out of a volcano and solidifies near the vent. The gas bubbles inside the magma cause it to be more viscous and sticky, which makes it pile up into a dome-shaped plug. As more magma is forced up from below, the plug can grow larger and larger until it eventually explodes, releasing ash, gas, and other volcanic materials. Plug domes are common features of stratovolcanoes, which are tall and steep volcanoes that are built up over time by successive eruptions of lava, ash, and other volcanic materials.

Pergunta 48 Relatório
The rotation of the earth on its own axis result in?
Detalhes da Resposta
The rotation of the earth on its own axis is the reason for day and night. As the earth rotates, half of it is facing towards the sun (daytime) while the other half is facing away from the sun (nighttime). This rotation takes approximately 24 hours to complete, resulting in the familiar pattern of day and night that we experience every day. The varying lengths of day and night at different times of the year and the changes in the altitude of the midday sun at different times of the year are caused by the tilt of the earth's axis and its orbit around the sun, not just its rotation on its axis. The four seasons are also a result of this tilt and orbit.
