• Net

• House

• Bag

• Blanket

How is the atmosphere heated in the greenhouse effect?

• The sun directly heats the atmosphere.

• The greenhouse gases absorb the sun's rays.

• The greenhouse gases trap heat that comes off the earth's surface.

• The ground warms up.

Global warming is man made. Which statement best explains why it is man made?

• Greenhouse gases are naturally occurring.

• Human activities produce more greenhouse gases.

• There are more greenhouse gases in the atmosphere.

• The atmosphere absorbs heat from the ground.

Select the best phrase which explains how the orbit change of the earth can affect its climate.

• Orbit moves further from the sun

• Orbit moves in a narrow orbit.

• Orbit goes from circular to elliptical.

• Orbit goes from circular to a smaller circular orbit.

A volcano cools the climate. Why is this?

• Ash blocks the light of the sun.

• Ash heats up but this cools the surrounding atmosphere.

• Sulphur dioxide changes the atmosphere.

• Every 8 years

• Every 15 years

• Every 100 years

• Every 11 years

Why do many sunspots, which are cooler, lead to warmer temperatures on earth?

• They block out the sun's energy.

• The areas around the sunspots are even hotter.

• They interfere with our temperatures.

• They are cool but they themselves release heat energy.
