• convection
• contraction
• radiation

The transmission of energy by two objects touching is called

• conduction
• convection
• contraction
• radiation

The main reason that we have currents in the ocean and air is

• the sun heats the air and ocean evenly everywhere
• the heat inside the earth heats the ocean and the ocean heats the air
• the sun cannot heat both the air and water, so one must heat the other
• the sun heats air and water more at the equator because it receives more direct sunlight
