1 There will be a Science quiz on Friday (tomorrow). There are 3 main areas to study for this test!

2 Make sure you know all 12 words on your vocabulary page. You need to know the layers of the atmosphere. You also need to understand the Greenhouse Effect and label the steps in order.

3 Lets practice some questions to see if you are ready for your test.

4 What do we call the blanket of air that surrounds Earth, reaching to about 700 km above the surface? A B C D meteorologisttroposphere weather atmosphere 1

5 What do we call the device or tool used to measure air pressure? A B C D windbarometer air pressure air 2

6 What do we call an area of higher air pressure than that of the surrounding air? A B C D high air pressuretroposphere barometer atmosphere 3

7 What do we call the movement of air over Earths surface? A B C D meteorologistwind low air pressure atmosphere 4

8 What do we call the invisible, odorless and tasteless mixture of gases that surrounds the Earth? A B C D greenhouse effectweather barometer air 5

9 What do we call the layer of the atmosphere closest to the surface of Earth? A B C D tropospheremeteorologist greenhouse effect air pressure 6

10 What do we call a scientist who studies the atmosphere and forecasts the weather? A B C D meteorologistweather low pressure area barometer 7

11 What do we call the process by which heat from the Sun builds up near Earths surface and is trapped by the atmosphere? A B C D meteorologistweather greenhouse effect air pressure 8

12 What do we call an area of lower air pressure than that of the surrounding air? A B C D wind pressurebarometer low air pressure weather 9

13 What do we call the condition of the atmosphere at a certain place and time? A B C D weatherbarometer air pressure meteorologist 10

14 What do we call the push of air in all directions against its surroundings? A B C D greenhouse effectbarometer nitrogen air pressure 11

15 There are four main gases that make up air. Can you name all four? nitrogenoxygen carbon dioxide water vapor 12

16 The greenhouse effect is the process by which heat from the Sun builds up near Earths surface and is trapped by the atmosphere. 13 Look at the 4 steps on the next slide. Number the steps in order from 1 through 4 as they explain the order of the greenhouse effect.

17 13 Heat rays from Earth rise into the atmosphere. Water vapor, carbon dioxide, and other gases trap some heat rays, and the atmosphere warms up. Suns rays strike the Earth. Some heat rays escape into space

18 Now lets look at the layers of the atmosphere. 13 Choose the best answer for each of the following questions.

19 In which layer of the atmosphere does weather, clouds, and smog occur? A B C D mesospheretroposphere thermosphereatmosphere 1

20 In which layer of the atmosphere would you find the ozone layer? A B C D stratospheretroposphere thermosphereexosphere 2

21 In which layer of the atmosphere do we live in? A B C D mesospherestratosphere troposphereatmosphere 3

22 In which layer of the atmosphere do meteors generally burn up? A B C D mesospheretroposphere thermospherestratosphere 4

23 Which layer of the atmosphere is between the thermosphere and space? A B C D mesospheretroposphere exospherestratosphere 5

24 Which layer of the atmosphere is the only layer in which humans can live without using special equipment for existence? A B C D mesospheretroposphere thermospherestratosphere 6

25 7 EARTH Identify the 5 main layers of the Earths atmosphere. Troposphere Stratosphere Mesosphere Thermosphere Exosphere

26 Are you ready for tomorrows test? Be sure to study your notes! Bring a library book to class with you tomorrow.
