2 Q1.Choose the best word from the word bank to complete each sentence Front Convection Currents 1. Front boundary between two air masses 2. Convection currents gases or liquids rise and sink in a circular path. Q2.Answer the following questions: 1. What are the three components of Air : Nitrogen, Oxygen, Carbon dioxide 2. When the Cool air and the warm air are beside each other where one rises and the other sinks, what forms? Convection currents 3. The most important properties of air masses are : Humidity, temperature 4. Write the Three types of fronts: Warm front, cool front, stationary front 5. What causes warm air containing water vapor to rise quickly to the clouds? Cold air 6. After the Warm air rises, what happens to it in the clouds before sinking it becomes cool or cold air 7. State the 5 layers of Atmosphere in order. Troposphere Stratosphere Mesosphere Thermosphere Exosphere 2 P age Kingdom School Teacher : Lama El Ghali Term 2

State 4 parts of the weather to be described when analyzing and studying the weather Precipitation, wind speed, clouds, temperature Q3.Circle the best answer: 1. As you go up through the 5 layers, temperature and air pressure a. Stay the same b. Change 2. Land cools and warms more than water? a. Quickly b. Slowly c. Same 3. The difference in Temperature above land and ocean cause a. Weather b. Storms c. Winds d. All of the above 4. In Cool Air, particles are a. Close to each other b. Apart from each other c. In the same place whether in cool or warm air. 3 P age Kingdom School Teacher : Lama El Ghali Term 2

4 5. When you go higher, air pressure gets a. Lower and particles get close to each other b. Higher and particles get close to each other c. Higher and particles get apart from each other d. Lower and particles get apart from each other 6. An Air mass is a. A huge body of air b. A huge body of air of different properties c. A huge body of air of the same properties 7. A front is a a. Boundary between two air fronts b. Boundary between two air masses c. Wall formed between two air masses 8. When a Warm air mass moves quickly and bumps into a cold air mass, the kind of front formed is a. Cold front b. Warm front c. Stationary front 9. When we talk about when the climate includes, we mean : a. Average amount of precipitation b. Average temperature c. How much the temperature changes during the year d. All of the above. 10. Areas on opposite sides of the mountain have a. Same climate because land temperature is the same all over. b. Different climate because higher land is warmer c. Different because higher land is cooler 4 P age Kingdom School Teacher : Lama El Ghali Term 2

5 11. Oceans can affect a climate by a. Fastening the rise and fall of the air temperature b. Slowing the rise and fall of the air temperature 12. Causes of climate change are : a. Volcanic eruptions, b. Asteroid c. Carbon dioxide d. Meteorite impacts e. All of the above Q4.Write in the correct order of : The formation of Thunderstorms: 3 Then Precipitation occurs Rain falls 1 Moist air raises quickly - Upward 2 Air condenses clouds are formed The formation of Tornadoes: 3 Upward winds lift one end up (of the funnel cloud) 2 Column of air in between starts to spin (funnel cloud) 1 Layers of wind blow at different speeds (and / or at different directions) 4 Downward winds push other end down 5 P age Kingdom School Teacher : Lama El Ghali Term 2

6 Q5.Fill in the blanks from the words below: Rainfall Wind speed Wind direction Air pressure Humidity A barometer measures Air pressure An anemometer measures wind speed A wind vane measures wind direction Hygrometer measures humidity Rain gauge measures rain fall Q6.True (T) or False (F). 1. False Weather and climate have the same meaning where weather is considered the weather conditions over a long period of time and is made up of all the conditions in one place at a single moment 2. False temperature of the air near an ocean changes as quickly as air inland. 3. True Ocean currents affect the climate. 6 P age Kingdom School Teacher : Lama El Ghali Term 2
