Answer… B. Temperature
During the day, the portions of Earth’s surface that receive sunlight absorb energy in the form of heat. During the night, Earth’s surface radiates this energy back into space. What is the main form of radiation released by Earth at night? A.visible light B.gamma rays C.infrared radiation D.ultraviolet radiation
Answer… C. Infrared radiation
Different areas of Earth’s oceans receive different amounts of energy in the form of heat, resulting in ocean currents and weather patterns. What is the main source of this energy? A.kinetic energy from tides B.kinetic energy from ocean currents C.energy transfer within Earth’s crust D.electromagnetic radiation from the sun
Answer… D. Electromagnetic radiation from the sun
Conduction happens as energy flows from a warmer object to a cooler object. Which of the following is an example of conduction? A.electromagnetic radiation transfers energy from the sun to Earth B.warmer air is pushed upward and out of the way by cooler air C.cooler air molecules come in contact with warm ground, causing energy to be passed to the air D.dense water sinks to the ocean floor and less dense water moves to the ocean surface
Answer… C. Cooler air molecules come in contact with warm ground, causing energy to be passed to the air

Answer… A.the doldrums
The Coriolis effect is the curving of the path of a moving object. How does the Coriolis effect influence the wind? A. It causes winds to move in straight paths. B. It changes the height at which wind travels. C. It causes the air to move. D. It changes the direction of the wind.
Answer… D. It changes the direction of the wind
