Answer:
The total number of species living in a particular area is referred to as its Biodiversity .
Explanation:
Biodiversity -
Biodiversity is defined as the variability and the variety of life existing on the planet Earth . Biodiversity measures the variation in the species , genetics and the ecology of the Planet . In the terrestrial level , the biodiversity is greater near the equator , due to warmer climate and higher level in production .
The biodiversity is not uniformly distributed on the planet , and is basically richer in the tropical region . Less than 10 percent of the Earth's surface is covered by the tropical forest ecosystems and contains around 90 percent of the world's species .
The diversity of marine life is higher near the Western pacific and in the mid latitude band , where the sea surface temperature is highest .

The correct answer is D. Use of CFCs
CFCs are very dangerous for the environment and destroy the atmosphere which in turn lowers air quality. They are commonly known as Freon due to a brand of CFCs found in fridges.
Answer: C.
Air masses that are hot and dry, and are responsible for heatwaves of summer in the western half of the United States.
Explanation: Air masses have fairly uniform temperature and moisture content in the horizontal direction (but not uniform in vertical). Air masses are characterized by their temperature and humidity properties. The properties of air masses are determined by the underlying surface properties where they originate.
Air that stands over the Caribbean Sea, for example, becomes a warm, humid maritime tropical air mass, while air that lies in the Arctic regions of northern Canada takes on the cold and dry characteristics of its surroundings and becomes a continental polar air mass.
