Answer:

B. Many species are common in only one area of the world.  

Explanation:

Species that occur in only one region of the world are called Endemic Species.

According to biogeography, an endemic species is that animal or plant species that occurs only in a particular area or geographic region. Endemism is caused by any physical, climatic and biological barriers that effectively delimit the distribution of a species or cause its separation from the original group. When the separation occurs for a long period, the isolated group undergoes a natural selection that develops in it a differentiation of other members of the species.

The Blue Macaw is an example of an endemic species of tropical rainforests in South America.

explain the differences between normal air circulation and how the air behaves when a temperature inversion occurs
dybincka [34]

Temperature inversion or thermal inversion is a phenomenon during which the temperature increase when there is an increase in the altitude. It is an uncommon process that happens in the troposphere-the layer of atmosphere closest to the earth.    

When there is an increase in temperature with altitude, that warm air acts as a blockage for the cool air near the surface of the earth. So this is just opposite to the normal behavior of the air, where it becomes cooler with an increase in altitude.

So how air circulation behaves during inversion?

So as we said that the cool air nearer to the earth will be blocked by a layer of warm air. This blockage will hinder the circulation of air upwards from the lower layers. Let’s see how:

• As we know that, warm air is less dense and more buyout than cool air and normally less dense warm air is close to the earth and cool air is in above layers. But when the process is reversed, this warm air acts like a blanket for the proper circulation of air. Due to this, many environmental pollutants which normally leave the earth during air circulation get trapped in our air.  

• The trapped environmental pollutants like nitrogen oxides and hydrocarbons get convert into harmful ozone that ultimately deteriorates the quality of air and causes problems like smog.

• The improper air circulation also causes suspension of the harmful gases near the earth instead of allowing them to leave the earth atmosphere. This ultimately causes air pollution.  

• When smoke will not rise, carbon dioxide will be build up in the atmosphere; this will cause greenhouse effect and global warming.

Therefore, air circulation behaves very different during temperature inversion process and poses hazardous effects on global climate.

Hope it helps! :)
