class-4-Science-Weather -1 1 / 20 What causes changes in weather? Water evaporetion Cloud formation Humidity of air Interaction of air mass 2 / 20 When temperatures fall below 0°C, what forms in a cloud? 7Dew Water droplets Ice crystals Gases 3 / 20 As surface currents move, They release heat quickly They carry warm or cool water to different locations They influence the amount of solar energy an area receives They bring warm temperatures to the West Coast 4 / 20 What is a cloud made of? Snow Warm air Gases Water droplets 5 / 20 What happens when the rate of evaporation equals the rate of condensation? The dew point is reached The humidity decreases Clouds form Precipitation occurs 6 / 20 The rate of evaporation of water is slower when: The area of exposed surface is greater The temperature is higher The humidity of the surrounding air is higher The wind is stronger 7 / 20 Earth's natural heating process is called 7Global warming The Milankovitch theory The greenhouse effect An ice age 8 / 20 Global warming may be caused by: A decrease in carbon dioxide concentrations An increase in carbon dioxide concentrations The tilt of the earth's axis. Changes in weather patterns 9 / 20 What do scientists use to express the amount of water vapour in the air? Relative humidity Relative point Vapour pressure Dew point 10 / 20 The sun's energy causes water to change states through: Relative humidity Weather Ice crystals The water cycle 11 / 20 The short-term state of the atmosphere is called: Dew point Weather Water cycle Climate 12 / 20 7Changes in weather are caused by the interaction of: Anticyclones Cyclones Air masses Fronts 13 / 20 Changes in weather are the interaction of: Storm surges Clouds Tornadoes Air masses 14 / 20 Which of the following is NOT true of an ice age? Ice sheets advance and get bigger 7There have been a few major ice ages Ice forms in high latitudes and moves towards lower latitudes A mixture of periods of cold and periods of warmth 15 / 20 When droplets in a cloud reach a certain size, they: Change the climate of an area Form a cold front Cause an electric discharge 16 / 20 What is water cycle? Water moving between the atmosphere, the land, and the oceans Water droplets forming on surfaces7 7Evaporatin of water Air pressure sinking and then rising 17 / 20 Which of the following statements is NOT true about winds? Winds carry evaporated water away from the ocean surface Winds blow from areas of high pressure to areas of low pressure Winds move in unpredictable patterns across the earth's surface Winds carry solar energy to and from different locations 18 / 20 Which of the following weather conditions causes the most deaths? Hail Thunderstorm Rain Cyclone 19 / 20 Which of the following decreases as elevation increases? Precipitation Latitude Clouds Temperature 20 / 20 Which of the following is the cause of the change of seasons?
