Desertification is a type of land degradation in which a relatively dry area of land becomes increasingly arid, typically losing its bodies of water along with its vegetation and wildlife. The Gobi and Sahara deserts are growing at an alarming rate due to desertification. Which of these does NOT
contribute to desertification?
A) Overgrazing
B)
Soil erosion
C)
Wind erosion
D) Conserving Water

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
