Question 2

Climate-

Answer 2

the weather conditions prevailing in an area in general or over time (long term averages)

Question 3

Heat-

Answer 3

the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object. Such energy transfer can occur in three ways: radiation, conduction, and convection.

Answer 12

the amount of water vapor in the air

Question 13

Relative humidity-

Answer 13

the percentage of water vapor in the air compared to the maximum amount the air could hold

Question 14
