Oxygen, Carbon dioxide, and water. |
|
3) What is air pressure
|
The force column of air applies on the air or a surface below.
|
|
4) What is altitude
|
The height of an object or point in relation to sea level or ground level.
|
|
5) What happens to air pressure as the altitude increases
|
It decreases.
|
|
6) Name the four layers of the atmosphere
|
Troposphere, stratosphere, mesosphere, thermosphere, exosphere
|
|
7) What is important about the troposphere
|
Weather appears there.
|
|
8) What is ozone
|
Protects Earth from ultra violet rays that can kill plants, animals, and other organisms/can cause skin cancer in humans.
|
|
9) What atmosphere layer contains the ozone layer
|
Stratosphere.
|
|
10) Which atmospheric layer is the coldest
|
Thermosphere.
|
|
11) What happens in the ionosphere
|
Collects ions to reflect on radio waves.
|
|
12) What is radiation
|
Transfer of thermal energy by electromagnetic waves.
|
|
13) What happens to the radiation once it enters the atmosphere
|
It becomes heat.
|
|
14) What is conduction
|
Transfer of thermal energy by collisions between particles of matter.
|
|
15) What is convection
|
Transfer of thermal energy by the movement of particles of matter.
|
|
16) What is a convection current
|
Way molecules circulate.
|
|
17) What three processes heat the Earth its atmosphere
|
Green house effect
|
|
18) What is the green house effect
|
Light reflects off the glass and heat comes in but can’t go out.
|
|
19) What gas in particular is responsible for the greenhouse effect
|
Thermal/carbon dioxide.
|
|
20) What is global warming
|
Were we try to use less pollution in the objects .
|
|
21) What is wind
|
Movement of air from areas of high pressure to area low pressure.
|
|
22) What creates wind
|
Differences in pressure.
|
|
23) What causes an area of high pressure
|
Cold air puts less pressure on earth, high altitude.
|
|
24) What causes an area of low pressure
|
At higher altitudes, the air is less dense because air molecules are farther apart.
|
|
25) What direction on the Earth does wind generally move
|
An west to east movement.
|
|
26) What is the Coriolis effect
|
A deflection of moving objects when the motion is described relative to a rotating reference frame.
|
|
27) What are two types of wind
|
Westerlies and polar easterlies.
|
|
28) What are trade winds; where are they located
|
Trade winds are steady winds that flow from east to west between 30*N and 60*S.
|
|
29) What are the Doldrums; where are they located
|
A belt of converging winds and rising air encircling the Earth near the Equator.
|
|
30) What are horse latitudes; where are they located
|
A belt of calm air and sea occurring in both the northern and southern hemispheres between the trade winds and the westerlies.
|
|
31) What are westerlies; where are they located
|
Steady winds that flow from west to east between latitudes 30*N and 60*S.
|
|
32) What are polar easterlies; where are they located
|
Cold winds that blow from the east to the west near the North Pole and South Pole.
|
|
33) What is the jet stream
|
Narrow band of high winds near the top of the troposphere.
|
|
34) What affects local winds
|
Local winds occur whenever air pressure is different from one location to another.
|
|
35) What are the two types of air pollution
|
Acid precipitation and smog.

Pollution.
|
|
40) What causes the majority of sulfur oxides in the air
|
The burning of coal from energy plants
|
|
41) What is acid precipitation
|
When sulfur dioxide and nitrogen oxide combine with moisture in the atmosphere and form precipitation that has a pH lower than normal rain water.
|
|
