class-4-Science-Weather -1 1 / 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 2 / 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 3 / 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 4 / 20 What do scientists use to express the amount of water vapour in the air? Vapour pressure Relative humidity Dew point Relative point 5 / 20 Which of the following weather conditions causes the most deaths?
