Define atmosphere.
What is a mixture of gases that surrounds the earth.
100
Define air pressure.
What is a measure of the force that air molecules push on a surface.
100
Define altitude.
What is the height of an object above the earth's surface.
100
Define air temperature.
What is the speed that the air molecules are moving.
100
Define and give an example of conduction.
What is transferring thermal energy by contact. Shaking hands.
200
What is the greenhouse effect and how is it good?
What are gasses that trap thermal energy. It keeps our planet warmer than it should be at night.
200
Define wind.
What is moving air.
200
What is humidity?
What is water in the air.
200
Define weather.
What is the condition of the atmosphere at a particular time and place.
200
What is a cloud?
A collection of millions of tiny water droplets or crystals.
300
What are jet streams.
What are narrow belts of high speed winds that blow high in the troposphere.
300
What is global warming and give an example of one bad thing that can happen as a result.
What is a rise in average global temperature. Rise in sea levels and more intense storms.
300
Define air mass.
What is a large amount of air with similar characteristics like temperature and humidity.
300
About how much pressure is felt by each person.
What is one ton.
300
Identify these cloud types
What is from left to right, cirrus, stratus, cumuls
400
List the names of the levels of the atmosphere from the earth to space.
What is the troposphere, stratosphere, mesosphere, and thermosphere.
400
Explain how hail forms.
What is the hail stone is sent high into the cloud where it freezes. As it falls it collects moisture and grows layers.
400
Name the four types of precipitation.
What is rain, sleet, snow, and hail.
400
Define and give an example of radiation in the form of transferring heat.
What is transferring energy in the form of waves. Example the sun.
400
What is the most abundant gas in the atmosphere?
What is nitrogen.
500
Explain what caused the thinning of the ozone and why it's a bad thing.
What is CFC's from old refrigerators get into the atmosphere and combine with ozone to break it down. This is bad because the ozone layer absorbs radiation that can lead to cancer.
500
Explain why as you gain altitude, you lose air pressure.
What is there is less air particles over your head pushing down on you. Gravity causes most of the air particles to be closer to the surface.
500
Explain the water cycle in detail.
What is water is evaporated due to the radiation from the sun. Because the water vapor is less dense than the air around it, it rises. When it reaches high altitude, the cold air condenses the water into a cloud. As the particles in the cloud join together they form precipitation that falls when it gets too heavy to hold. The precipitation collects in lakes, rivers, and oceans.
500
Explain how a cloud forms.
What is the sun heats plants or bodies of water until they turn into water vapor. The water vapor rises in altitude because it is less dense than the air around it. As it gets higher in the air, the air gets colder and causes it to condense into a cloud.
500
Explain what causes wind.
What is a difference in air pressure caused by uneven heating of the earth.
