Flashcards in Ch 6 Water cycle/Weather Deck (20):
The amount of water vapor in the air is
Boundaries between air masses
Leading edge of a cooler mass of air, replacing (at ground level ) a warmer mass of air
Warm air rises over a massif old air
What happens when cold air meets warm air?
Warm air, which is lighter, is pushed on top of the cold air. The airfoils as it rises and water vapor condenses forming clouds. Some form of precipitation usually occurs, most like thunderstorm.
Flat, hazy, grayish clouds. What you see on a cloudy day
Measures air pressure
Measures wind speed
Measures humidity in the air
Greenhouse gases can be beneficial because it
Keeps the earth warmer. Without it, the earth would be about 54 degrees colder and unable to sustain life.
About ? of theEarths surface is covered with water
Ocean water is ? Fresh water is ?
Why is the Baltic Sea less salty than the other seas?
Many rivers (fresh water) flow into it.
What does the sun do in the water cycle?
Water vapor evaporates in the suns warmth
When water vapor becomes a liquid.
When moist air rises
It cools, condenses, and forms a cloud
Describe the water cycle
Precipitation falls to the ground.
The sun warms the liquid and turns it to water vapor
The water vapor rises and condenses to a cloud.
A force that surrounds the earth
When there is an area of low pressure nearby, air
Becomes less dense
