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

If we boil water in a pot on an electric burner. How is our simulation of demonstrating convection currents different than the currents in the atmosphere and ocean?

• the warm air in our model sinks instead of rises

• the heat source for Earth is the sun which heats from above

• the currents are all flowing in the same direction

• warm water is less dense than warm air causing a difference between the models

You're trying to explain to a friend how convection works.  You want to draw a diagram showing what happens to air when it's heated by the sun.  What should you draw?

• A diagram with cool air in Earth's atmosphere rising

• A diagram with cool air near Earth's surface rising

• A diagram with warm air in Earth's atmosphere sinking

• A diagram with warm air near Earth's surface rising
