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
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
