the direct transfer of energy through space by electromagnetic waves

the direct transfer of heat energy from one substance to another as the two substances are touching

the transfer of heat energy by the movement of a fluid (liquid or gas)

a continuous process by which water moves from bodies of water, land, and living organisms on Earth's surface to Earth's atmosphere and back to Earth's surface

molecules of liquid water escape into the air as water vapor

evaporation of water from plants

molecules of water vapor in the air become liquid water

water molecules, in any form, fall from clouds and reach Earth's surface

precipitation that run off of land and eventually flows back into oceans

water that soaks into the soil as precipitation falls on land

the process in nitrogen from the atmosphere is changed into nitrogen compounds that living organisms can use
