Which is the middle layer in the atmosphere where meteors burn up?
Mesosphere
300
What type of cloud looks like flat, gray sheets covering the sky?
Stratus
300
How is dew formed?
When the air cools during the night, the air cannot hold as much water vapor, so the water has to come out.

How do hurricanes get started?
Warm air over an ocean rises quickly, cool air moves in, and creates very low pressure. The pressure difference makes the winds become extremely strong.

Name 2 reasons that areas may change climate over time.
Continental drift, periods of gradual cooling/heating, El Nino
What type of clouds are very high, wispy, and made of ice?
Cirrus
400
How is snow formed?
Snowflakes can form in cold air when gas turns to solid by creating ice crystals.
They also can form around a frozen cloud droplet.

What is a warm front?
Warm air moves into a slower moving or stationary cold air mass. As warm air rises into the cooler air, clouds form and create moderate rainfall in the area.

Name 3 factors that affect climate.
Temperature, precipitation, ocean currents, winds, major landforms
500
What gas is most common to find in our atmosphere?
Nitrogen

How are clouds formed?
As sunlight hits the ground, the ground heats the air above it. The warmer, vapor-filled air rises. As the air rises, it cools. When the air reaches it’s dew point, water vapor high up in the sky condenses to form a cloud.

How is sleet formed compared to how hail is formed?
Sleet starts as snow, melts on the way down, and refreezes before it hits the ground.
Hail is formed when the wind blows in storm cloud which makes particles of ice freeze while moving up and down in the cloud.

Explain what happens with a cold front.
Cold air moves into a slow moving or stationary warm air. Cold air sinks under the warm air and storms form quickly. Thunder, lightning, hail, sometimes tornadoes occur.
