Explanation:
Differences in temperature lead to variations in air pressure around the world. Low-pressure areas are created when air rises. It is called low pressure because the weight of the air above the Earth's surface is lower than average. High-pressure areas are created when air sinks. It is called high pressure because the weight of the air is above average when it sinks to the Earth's surface.
Low-pressure areas are associated with cloud and precipitation (rainfall) because:
as the air rises it cools, condenses and forms clouds
the water droplets in the clouds increase in size
they eventually become too heavy to be held and fall as precipitation
The air above the Equator is very hot and rises, creating an area of low pressure. The Equator experiences high amounts of rainfall due to this rising air resulting in a warm and wet equatorial climate (eg the Amazon and Congo tropical rainforests).
High-pressure areas are associated with dry, warm and settled weather conditions. This is because sinking air does not result in precipitation.
Answer:
Geographic isolation
Explanation:
Geographic isolation -
It is considered to be the method by which the group of some specific living organisms gets isolated from rest of the organisms , which disables the species from sharing any genetic information , is referred to as geographic isolation .
The process of geographic isolation can be due to any accident or any coincidence .
Hence , from the given scenario of the question ,
The correct term is geographic isolation .
Artificial Boundaries, because countries are way more likely to dispute and fight wars over this type of boundary, than natural boundaries <span />
