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

Dense water sinks to the ocean floor and less dense water moves to the ocean surface

Electromagnetic radiation transfers energy from the sun to earth

Warmer air is pushed upward and out of the way by cooler air.

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