Answer 4

meteorology

Question 5

Answer 5

weather

Question 6

It is the net loss of water from a surface by means of a change in the state of water from a liquid to a vapor, and the transfer of this vapor to the atmosphere.

Answer 6

evaporation

Question 7

It is the process by which precipitation reaching the earth’s surface is returned to the atmosphere as vapor through evaporation from wet surfaces and transpiration by plants.

Answer 7

evapotranspiration

Question 8

Runoff is produced when this property of the soil surface is exceeded,

Answer 8

infiltration rate
