Which is a possible result of higher air temperatures caused by global warming?

increase in sea level
freezing of polar ice caps
rapid evaporation of water in the soil
flooding of low-lying coastal area

C. rapid evaporation of water in the soil

Explanation:

Global warming is defined as increase in the Earth's average temperature for a long term.

One of the possible reason of increasing air temperature is that greenhouse gases are trapping more heat in the air and causes rise in temperature. Due to high air temperature, water get evaporated at higher rate from the soil and soil lost its moisture rapidly.

Continuous decline in soil moisture increases irrigation requirement for agriculture and leads to decline in food production and even result into desertification.

Hence, the correct option is C.
