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.

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 a g e K i n g d o m S c h o o l T e a c h e r : L a m a E l G h a l i T e r m 2 11. Oceans can affect a climate by
a. Fastening 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 Æ Rain falls
1 Moist air raises quickly - Upward
2 Air condenses Æclouds 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 a g e K i n g d o m S c h o o l T e a c h e r : L a m a E l G h a l i T e r m 2 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.
