Hail Rain Thunderstorm Cyclone 13 / 20 Which of the following statements is NOT true about winds? Winds move in unpredictable patterns across the earth's surface Winds carry solar energy to and from different locations Winds carry evaporated water away from the ocean surface Winds blow from areas of high pressure to areas of low pressure 14 / 20 Global warming may be caused by: An increase in carbon dioxide concentrations Changes in weather patterns A decrease in carbon dioxide concentrations The tilt of the earth's axis. 15 / 20 What is a cloud made of? Gases Warm air Snow Water droplets 16 / 20 What do scientists use to express the amount of water vapour in the air? Dew point Relative humidity Relative point Vapour pressure 17 / 20 The rate of evaporation of water is slower when: The humidity of the surrounding air is higher The area of exposed surface is greater The temperature is higher The wind is stronger 18 / 20 Which of the following is NOT true of an ice age? 7There have been a few major ice ages Ice forms in high latitudes and moves towards lower latitudes Ice sheets advance and get bigger A mixture of periods of cold and periods of warmth 19 / 20 The short-term state of the atmosphere is called: Dew point Climate Water cycle Weather 20 / 20 Changes in weather are the interaction of: Air masses Storm surges Clouds Tornadoes Your score is LinkedIn Facebook Twitter VKontakte

She poured 200 ml of water into each of the three containers shown below. She put the containers under the sun and recorded the time taken for the water to evaporate completely from each container. The aim of the experiment was: To find out whether is same the rate of evaporation A and C To find out whether the area of exposed surface affects the rate of evaporation To find out whether the area of exposed surface does not affect the rate of evaporation 3 / 15 Humidity is: The amount of water vapour in the air When a gas becomes a liquid The continuous movement of water The temperature below dew point 4 / 15 In the process of boiling: Floating particles settle down Colour disappears Germs get killed Foul smells escape 5 / 15 Stream-like movements of water that have a large effect on an area's climate are: Surface currents Dew Storm surges Water vapour 6 / 15 The amount of bleaching powder for purifying water should be: 1 teaspoon in a glass and 3 teaspoons of this in a bucket 1 teaspoon in a glass 1 teaspoon in a bucket and 3 teaspoons of this in a glass 1 teaspoon in a bucket 7 / 15 At higher elevations, The temperature of the air is lower There is no rain-shadow effect The dew point is higher The temperature of the air is higher 8 / 15 Washing clothes near a water source is harmful because the dirt and soap released: Are absorbed by the soil to reach sub-soil water Flow into the water Are responsible for doing all of the above Are left behind to create slush 9 / 15 When air is nearly saturated and temperature drops, what is reached?
