Answer:
Population growth is a problem.
Explanation:
Population is a problem because we have to worry about if we have enough resources to support them and there has been a scientific study done that proves more carbon dioxide is put into the air which doesn't help with air pollution.
Answer:
Country C
Explanation:
an economy that is producing raw materials is typically the least developed, as most other economic sectors that are described need industrialization, manufacturing, or a service/technology economy, which is usually more developed than a industrial economy.
Crude oil is made of several components- called hydrocarbons- mixed together and can be chemically separated. These components are, majorly, fuels. Examples of these fuels are; diesel, petrol, kerosene, liquefied petroleum gas and heavy oils such as bitumen (used on tarmac roads).
An oil refinery is basically a big plant that utilizes the chemistry of fractional distillation to separate the oil components. This involves boiling the crude oil at different temperatures to evaporate the different components that have different boiling points. Each component is later condensed and recovered separately.
Crude oil is a natural resource that is formed over millions of years from organic matter especially planktons. When the organic matter dies and settles at the bottom of oceans, they are overlaid by layers and layers of sediment. This, over time, subjects the organic matter to high pressure and temperatures and they metamorphose into crude oil.
Answer: A.Convergent
The northern margin of the Indian plate is being thrust under a portion of the Eurasian plate. This collision results in the creation of Himalayas and the Tibetan Plateau. This is an example of 2 continental crusts converging and this is known as convergent boundary.
Similarly, Aleutian Islands is formed by the the subduction of the northern part of the Pacific Plate and the NW North American Plate . Also the Andes is formed by the convergence of the Nazca Plate beneath the South American Plate.
The climates in the highlands are mostly affected by the level of precipitation that it received on an annual basis. The highland climates are mainly controlled by the polar and the artic masses which provide and influence with a great diversion to its temperatures, subtypes, diversity in the landforms, and life.
