Answer…

D. Electromagnetic radiation from the sun

Conduction happens as energy flows from a warmer object to a cooler object. Which of the following is an example of conduction?

A. electromagnetic radiation transfers energy from the sun to EarthB. warmer air is pushed upward and out of the way by cooler airC. cooler air molecules come in contact with warm ground, causing energy to be passed to the airD. dense water sinks to the ocean floor and less dense water moves to the ocean surface

Answer…

C. Cooler air molecules come in contact with warm ground, causing energy to be passed to the air
