QUESTION 18 What happens when light ray hits an object? O The object releases energy, its molecules move slower, and it becomes colder O The object absorbs energy, its molecules move faster, and it becomes warmer The object gives off light None of the above QUESTION 19 Heating of the Earth's surface and atmosphere by the sun drives O Radiation esithin the atmosphere and oceans, producing winds and oceans currents Convection OGravity OConduction QUESTION 20 Which of the following is NOT a way that energy transfers through the Earth System? O Radiation O Convection O Gravity O Conduction QUESTION 21 What are clouds made of? O Aerosols Tiny water droplets Large ice crystals OAll of the aboveExplanation / Answer
18. The object absorbs energy, its molecules move faster and it becomes warmer. The light wave is absorbed by the object and on absorbing the energy the energy gets converted into heat energy and warms the object
19. Radiation. The hot and cold temperatures at specific latitudes are due to uneven solar radiation. This uneven temperature causes wind and ocean currents.
20. Gravity. Energy is transferred from radiation, convection and conduction.
21. All of the above. A cloud is composed of tiny water droplets or ice crystals that are suspended in the air.
