8.10a quiz

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

The Sun warms the atmosphere and drives convection currents because -

• warm air is less dense, so it rises.

• the warmed air cools and makes rain.

• the cooler land pushes away warm air.

• warm air, in contact with cool air, rotates.

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
