There will be a Science quiz

on Friday (tomorrow).

There are 3 main areas tostudy for this test!

Make sure you know all 12words on your vocabulary page.

You need to know thelayers of the atmosphere.

You also need to understandthe Greenhouse Effect and

label the steps in order.

Let’s practice somequestions to see ifyou are ready for

your test.

11

There are four main gases that make up air.

Can you name all four?

1 2

3 4

nitrogen oxygen

carbon dioxide water vapor

12

The greenhouse effect is the processby which heat from the Sun builds

up near Earth’s surface and istrapped by the atmosphere.

13

Look at the 4 steps on the next slide.Number the steps in order

from 1 through 4 as they explainthe order of the greenhouse effect.

13

Heat rays from Earth riseinto the atmosphere.

Water vapor, carbon dioxide, andother gases trap some heat rays,and the atmosphere warms up.

Sun’s rays strike the Earth.

Some heat rays escapeinto space.
