vocab question- stratosphere
Farthest layer from earths surface and gradually blends above 500 km into space and is the coldest layer
The hottest layer in the atmosphere
The layer of the earths atmosphere that contains a high concentration of ions and free electrons and is able to reflect radio waves
The second most layer of the earths Atmosphere above the troposphere extending about 32 miles above earths surface .
Vocab question- Ozone layer
The protective barrier; protects earth from the suns harmful UV rays
The closest layer to earth and were all living organisms are.
The intensity of the sun; over exposure to UV radiation
A thin layer of gases surrounding the earth
Heat and a conductor through touch
Vocab question- Ionosphere
Occurs in the troposphere when the temperature increases as altitude increases
The layer of earths atmosphere that contains a high concentration of ions and free electrons and is able to reflect radio waves
The transfer of energy through electromagnetic waves
Describes wether circulating air motions will be weak or strong
How did Earth’s atmosphere form?
The absorption through clouds and particles in the atmosphere
Harmful UV rays and infrared light
When ions of the solar wind collide with atoms of oxygen and nitrogen from earths atmosphere.
Through volcanic ashes, water droplets, some solid particles pollen dust and salt
What was the atmosphere like in the early ages?
It is the same as the atmosphere now.
It was filled with water vapor and little carbon dioxide (CO2 ) and nitrogen.
71% nitrogen, 21% oxygen
71% oxygen, 21% nitrogen
What is the Earth primarily made of now?
78% oxygen 21% nitrogen 1% ozone,water vapor,Argon, carbon dioxide
78% nitrogen 21%oxygen 1% water vapor,Argon,carbon dioxide and ozone
what are the layers of the atmosphere in order
Stratosphere, mesosphere,troposphere,thermosphere exosphere
Mesosphere, thermosphere,stratosphere,troposphere exosphere
Troposphere ,stratosphere,mesosphere,thermosphere exosphere
Troposphere , exosphere,stratosphere,thermosphere mesosphere
How do air pressure and temperature change as altitude increases?
air pressure is greatest near Earth’s surface; the higher you go up the the lower the air pressure
The air pressure is lowest near earths surface; the higher you go the lower the air pressure
Air pressure is greatest near the exosphere and in space
Air pressure is greatest in the thermosphere
Why is Earth’s atmosphere important for life on Earth?
The atmosphere contains the oxygen, carbon dioxide, and
water necessary for life on Earth.Without
it, daytime temperatures would be extremely high and night-
time temperatures would be extremely low.
We don’t need an atmosphere because we would be able to create one on our own
what is the process to the following definition:
atmosphere cooled, the water vapor condensed into liquid. Rain fell and then evaporated from Earth’s surface repeatedly for thousands of years. Eventually, water accumulated on Earth’s surface, forming oceans. Most of the original CO2 that dissolved in rain is in rocks on the ocean floor. Todaythe atmosphere has more nitrogen than Co2
How did Earth’s present atmosphere form? (What were the events that lead to what we have now
How does energy transfer from the sun to earth?
The 2 main gases located in our atmosphere are?
Nitrogen and oxygen
Oxygen and carbon dioxide
Nitrogen and carbon dioxide
Carbon dioxide and water vapor
Describe the troposphere.
The farthest layer away from earth and gradually blends into space
2000 degrees Fahrenheit and is the hottest layer in the atmosphere
The layer closest to earth were all living organisms are and is were weather occurs
Middle layer and the coldest layer and protects us from meteorites
Which layer of the atmosphere do planes fly?
Troposphere
Stratosphere
Thermosphere
mesosphere
Why is the stratosphere an asset to the life on Earth?
The collisions during the making of the stratosphere caused an aurora
It keeps us warm
It protects us from meteors and Visible light
It contains the ozone layer which protects us from the suns harmful UV rays
How do air pressure and temperatures change as altitude increases?
as altitude increases temperature decreases
As Temperature decreases altitude decreases
temperature changes with altitude in the different layers of the
atmosphere.
Both temperature and Altitude increases
Which layer has a temperature pattern most like the troposphere?
Troposphere
Thermosphere
Mesosphere
Stratosphere
How does energy transfer from the sun to the atmosphere?
radiation is the process that transfers
energy from the Sun to Earth
Conduction is the process that transfers energy from the sun to the earth
Convection is the process that transfers energy from the sun to the earth
Latent heat is the process that transfers energy from the sun to the earth
What is the main difference between visible light and ultra violet light?
Earth absorbs UV light but does not absorb Visible light
Earth absorbs visible light but does not absorb UV light
What percent of incoming radiation is absorbed by gases and particles in the atmosphere?
50% of incoming radiation is absorbed by gases and particles in the atmosphere
5% of incoming radiation is absorbed by gases and particles in the atmosphere
20% of incoming radiation is absorbed by gases and particles in the atmosphere
25% of incoming radiation is absorbed by gases and particles in the atmosphere
What are the greenhouse gases
Water vapor,oxygen and nitrogen oxide
Argon,nitrogen and oxygen
Carbon dioxide,nitrogen and oxygen
Water vapor,carbon dioxide and methane
How many green house gases are there?
5

What happens to water when heat energy is absorbed?
A. Ice Melts B. Liquid Water Freezes C. Water vapor condenses
A
B
C
Describe how air circulates
It circulates to the west
It circulates to the north
Cold air rises and warm air sinks
Warm air rises and cold air sinks
Free answer question:
What are the differences in air circulation when the air is stable versus unstable?
During unstable conditions,ground-level air is much warmer than higher-altitude air. As warm air rises rapidly in the atmosphere, it cools and forms large, tall clouds. Latent heat, released as water vapor changes from a gas to a liquid, adds to the instability, and produces a thunderstorm.
