Q

What is ozone and how is it formed?

A

Ozone is an atmospheric gas. It is formed when the sun divides oxygen, which binds to another oxygen to make ozone.

Q

Name three things the atmosphere does for us :)

A

It protects us from from meteorites and radiation,

Keeps the earth at the right temperature (heats it)

And provides gases essential for life

Q

Colorful display of light produced when charged particles from the sun are attracted to earth’s magnetic poles. Cause ions in ionosphere to…

A

Auroras

16
Q

Northern Lights are called this

A

Aurora Borealis

17
Q

Radio waves travel to this layer and bounce off ions and return to earth. Allows up to have service.

A

Ionosphere

18
Q

Describe the differences between Tornadoes and Hurricanes (Typhoons).

A

Tornadoes start over land, hurricanes start over water
Tornadoes have faster wind speed, hurricanes have slower wind speed
Tornadoes have faster storm (passes quicker, hours), hurricanes have slower storm (weeks)
Tornadoes come mostly in spring and early summer, typhoons come mostly on the east coast/ Japan/ Asia
Tornadoes have unpredictable route, hurricanes don’t
Tornadoes have eye/center windy, hurricanes have eye/ center calm (see it)
Tornadoes have hail, hurricanes unlikely have hail

19
Q

Describe how the greenhouse effect works.

A

PROCESS OF ABSORPTION PF RADIATION of earth’s energy.

Greenhouse effect is natural, warms the Earth’s surface to a livable temperature, and gases can escape. Some stay.

20
Q

High speed rotating winds that extend downward from thunderclouds.

A

Tornadoes

21
Q

How do tornadoes form?

A

Cool, dry air from the north and warm, humid air from the Gulf of Mexico meet.

22
Q

Large circulating masses of clouds, wind, and rain with average diameters of about 373 Mi.

A

Hurricanes ( also called cyclones or typhoons )

23
Q

To be classified as a hurricane, winds much reach speeds greater than

A

73 miles per hour

24
Q

How was our early atmosphere created and how did it change to what it is now?

A

As earth was forming, volcanoes added gases to the atmosphere called “outgassing.” Photosynthetic plants added oxygen to the atmosphere. They converted carbon dioxide into oxygen which changed composition of the earth’s atmosphere.

25
Q

Gases contained in the early atmosphere

A

Carbon dioxide, ammonia, water, nitrogen, methane, hydrogen, and carbon monoxide.

26
Q

Current atmosphere composition ( gases / percentages )

A

99% nitrogen and oxygen. The other 1% are argon, carbon dioxide, and water (and other traces of gases).
