science final Flashcards
Explain how air at the surface of earth is heated
Energy transfers from the sun to the surface, & conduction occurs from the surface to the air
Why are clouds flat on the bottom?
This is the point where water condenses
How does Sunlight affect the temperature of land and water?
Sunlight can increase the temperature of land and water
Which of the following is not an atmospheric condition that can affect weather?
Heat index and Wind chill
How do prevailing winds that travel across large bodies of water affect the climate?
The prevailing winds make the climate more humid
In electric ovens, the heat in the oven comes from the bottom when baking something. However, cookies baking on the top shelf bake faster than cookies on the bottom shelf even though the bottom shelf is closer to the heat source. Explain.
The air at the bottom of the oven becomes less dense than the air at the top of the oven and rises. The hotter air stays at the top of the oven, and so it transfers more energy into the cookies. So, the cookies on the top shelf bake more quickly
Human activities, such as burning fossil fuels like coal, have an effect on the following
Weather and climate
Cool air is blowing from minneapolis to chicago, where the air is warmer. When the air from minneapolis reaches Chicago, clouds begin to appear. If there is no increase in the amount of water vapor in the air as it moves, what could explain why the clouds appear in the air in chicago?
The cool air pushed the warm air upward, which caused the warm air to cool, condense, and form from clouds.
The energy that drives weather on earth comes from
The sun
Give the most important reason why temperatures are typically colder as you move farther away from the equator
The angle at which light hits the Earth affects the intensity of light energy and therefore, temperature
