Earth's Atmosphere

Ace your homework & exams now with Quizwiz!

What is important about the Troposphere?

- All living things are located here - Contains all the water vapor in the atmosphere which produces weather and determines climate

What is the composition of the atmosphere?

- Nitrogen 78% & Oxygen 21% make up 99% - Carbon dioxide, hydrogen, argon, neon, and helium make up 1% - Always the same composition.

Why is the atmosphere important?

- Weather - Makes the Earth suitable for living things - Traps energy from the sun (harmful rays) - Keeps the Earth's surface warm enough for water to exist as a liquid - Protects the Earth from radiation and meteoroids - Soundwaves

How much bad Ozone is there and where is it located?

10% in the troposphere (pollution/smog)

How much good Ozone is there and where's it located?

90% in the Stratosphere

What is the alititude of the ionosphere?

90km to 300km

How thick is the mesosphere?

About 40km thick

How thick is the stratosphere?

About 40km thick

Photoinonication

And electronic knocked force free from an atom to form an ion (caused by UV Rays)

Why is the Earth divided into 5 layers?

Because of the change in air temperature

What do the electricity charged particles in the ionosphere do?

Bounce radio waves

Tropo

Change

CFC's

Chloro Fluoro Carbons

How does the atmosphere change as the altitude increases?

Density of air decreases

What is the ionosphere useful for?

Earth's communication system because it contains a lot of electricity charged particles

What is the last layer?

Exosphere

True or false: the earth is made up of 4 layers

False, Five

True or false: Ozone levels are at 21% in our atmosphere

False, Oxygen

True or false: the ionosphere layer stops most of the UV rays from the sun

False, Ozone

True or False: The stratosphere contains bad ozone -pollution/smog-

False, Troposphere

True or false: the stratosphere is the layer that eventually thins into outer space

False, exosphere

True or false: Oxygen makes up about 78% of the volume of atmospheric gases

False, nitrogen

True or false: The mesosphere contains a temperature inversion, colder on the bottom, warmer on the top

False, stratosphere

True or false: the different layers of the atmosphere are separated because of composition of gases

False, temperature change

True or false: the higher you go in the stratosphere the colder it gets

False, troposphere

True or false: the thermosphere has the smallest distance from the top to the bottom

False, troposphere

True or false: our original atmosphere was formed by gases released by earthquakes

False, volcanos

Thermo

Heat

What is in the troposphere?

Hot air balloons

Why does weather exist in the troposphere?

It contains all the water vapor in the atmosphere. The water vapor makes up clouds, rain, and other forms of precipitation.

What does the Ozone protect us from?

It protects us from rays which cause problems including skin cancer.

Where is the stratosphere located?

Just above the troposphere

Stratos

Layer

What gases are found in the atmosphere?

Nitrogen, oxygen, carbon dioxide, water vapor, and Ozone

What is the Ozone made up of?

O3

How much air does the troposphere contain.

Over 80% of all air in the atmosphere

How thick is the thermosphere?

Over 90km

The gas that organisms need for respiration

Oxygen

What is located in the stratosphere?

Planes

What does the mesosphere do?

Protects the Earth from meteoroids

What is in the Exosphere?

Satellites, Space Shuttles

What is the temperature of the thermosphere?

Sun rays are high here, creating high temperatures. Up to 1000* c

What is the thickness and temperature of the troposphere?

Temperature and thickness varies, between (9-16 km)

What occurs in the ionosphere?

The Aurora Boreaus (Northern Lights)

Why do planes travel through he stratosphere?

The air is thinner, so planes encounter less friction, therefore they fly faster and uses less fuel. It is also above weather.

Why does the ionosphere reflect long-distance radio signals back to earth?

The electronic ions and gases in the ionosphere transmit sound waves.

Which sphere is in the middle?

The mesosphere

What happens to the temperature in the troposphere as the altitude increases?

The temperature decreases

What happens to the temperature of the troposphere when the altitude decreases?

The temperature increases

What is the thickest layer?

The thermosphere

Which direction is the stratosphere warmer?

The top

What is the temperature of the mesosphere?

There is a wide variety of temperatures because there aren't many air molecules to absorb warmth. It is the coldest layer with a low of -120* c with a high of 0-27* c

Why would there not be any soil without the atmosphere?

There would be no weather. Which means no wind to cause weathering and erosion which breaks down rocks into soil.

True or false: Most of the atmosphere's water is located in the troposphere

True

True or false: Ozone is a form of oxygen gas

True

True or false: an increase in carbon dioxide emissions led to global warming

True

True or false: the presence of oxygen has in our atmosphere makes life possible

True

The major direct source of heat in the troposphere

UV rays

Ozone

Upper part of the stratosphere, a layer of gas that absorbs ultraviolet rays from the sun

Temperature inversion

Warmer towards the top due to the warm sun energy

What is located in the Ozone?

Weather balloons

What is the atmosphere?

a layer of gas that surrounds the Earth

What is gravity's role in the atmosphere?

holds the atmosphere in place

What do the gas molecules in the atmosphere due?

transmit sound waves
