Science Test 3 Flashcards
What causes winds?
A difference in temperature creates a difference in pressure. Air molecules move until they are evenly spread out.
High-pressure
Cold air
Air that has high density
Air near the north pole
Low-pressure
Hot air
Air that has low density
Air near the equator
Moving air
Evaporation starting, and ending location
Evaporation starts on the ground and then ends in the sky
Condensation starting location and ending location
Condensation starts in the sky and ends in the clouds
Runoff starting location and ending location location
Runoff starts in the ground and ends on lower ground
Evaporation starting state of matter, and ending state of matter
Liquid to gas
Condensation ending state of matter
Gas to liquid
Precipitation starting and ending state of matter
Liquid to solid/liquid
Runoff starting state of matter, and ending state of matter
Liquid to liquid
What are the four steps of the water cycle?
Evaporation, condensation precipitation and runoff
Explain why wind move from water to a beach during the day mention temperature pressure and why they move
Winds move from the water (high pressure) to the beach (low pressure) because the molecules are trying to be evenly space/balanced.
Describe a cold front
A cold air mass quickly moves in and pushes the warm air mass up. (Cold air is more dense than warm air.)
Describe a warm front
A slow, moving warm air mass moves in and above the cold air mass. (warm air is less dense than cold air.)
Describe a stationary front
Two air masses meet and they move sideways
