Weather Unit (Test) Review Flashcards
What is ozone and how is it formed?
Ozone is an atmospheric gas. It is formed when the sun divides oxygen, which binds to another oxygen to make ozone.
Name three things the atmosphere does for us :)
It protects us from from meteorites and radiation,
Keeps the earth at the right temperature (heats it)
And provides gases essential for life
What would happen if we did not have the ozone layer?
We would probably not live.
Where and when is the ozone layer is most depleted?
In Antarctica, during the spring.
How does air pressure change with altitude?
Density lowers as altitude increases.
Name the layers of the atmosphere in order from bottom to top.
Troposphere
Stratosphere
Mesosphere
Thermosphere
Which layer holds theozone layer?
Stratosphere
Name one area where the temperature stops its trend and goes the opposite way in a layer.
Tropopause
Layer where weather happens
Holds Earth’s water vapor, clouds/rain
Troposphere
In what layer does temperature decrease as altitude increases, and stops decreasing at the tropopause?
Troposphere
Temp. Mainly increases with altitude increase, stops increasing at stratopause. What layer?
Stratosphere
Has thin air, materi is burn up, little solar radiation absorbance, temperature decreases with altitude and stops decreasing at the mesopause. What layer is this?
The mesosphere
No boundary, marks and of atmosphere, merges with space.
Temp. Increases rapidly with altitude.
Thermosphere/ Exosphere
Not a distinct layer, is found between upper mesosphere and lower thermosphere.
The ionosphere
The layer that has a region of electrically charged particles and ions. Auroras are found here.
The ionosphere
Colorful display of light produced when charged particles from the sun are attracted to earth’s magnetic poles. Cause ions in ionosphere to…
Auroras
Northern Lights are called this
Aurora Borealis
Radio waves travel to this layer and bounce off ions and return to earth. Allows up to have service.
Ionosphere
Describe the differences between Tornadoes and Hurricanes (Typhoons).
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
Describe how the greenhouse effect works.
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.
High speed rotating winds that extend downward from thunderclouds.
Tornadoes
How do tornadoes form?
Cool, dry air from the north and warm, humid air from the Gulf of Mexico meet.
Large circulating masses of clouds, wind, and rain with average diameters of about 373 Mi.
Hurricanes ( also called cyclones or typhoons )
To be classified as a hurricane, winds much reach speeds greater than
73 miles per hour
