The troposphere is which layer of the atmosphere?
The 1st layer
The stratosphere is which layer in the Earth's atmosphere?
The second layer
The mesosphere is which layer?
The third layer of the Earth's atmosphere.
True or False: The thermosphere is the coldest layer.
False
The Greet word "exo" means?
outside
How far is the troposphere from the ground and how high does it extend to?
4-6 miles and extends up as high as 12 miles from the ground.
The stratosphere starts around how many miles up from the Earth?
7 miles
Which two layers is the mesosphere in between?
The Thermosphere and Stratosphere.
The thermosphere can extend as high as how many miles?
621 miles
Satellites
What does the Greek word "tropos" mean?
Change
What does the word strato sphere mean?
Means layer around the Earth.
How high does this layer extend to?
50 miles
What does the thermosphere protect Earth from?
Cold temperatures in outer space AND radiation from the sun.
The exosphere is made up of mainly what two gases?
helium and hydrogen
Why is most life on Earth found in the troposphere?
Because it has oxygen.
Why is the ozone layer important?
It makes sure the right amount of UV radiation from the sun hit the Earth.
Why is it difficult to fully study the mesosphere?
Because it's too high for planes and too low for satellites.
Another word for northern and southern lights.
Auroras
How are satellites able to orbit the Earth in the exosphere?
Because there is not much friction or resistance to disturb or bother the satellite.
How is the troposphere heated? Explain in your own words.
Logical explanation: Sunrays heat the ground and ocean and then the heat bounces back into the troposphere.
True or False: There is not much oxygen at the top of the stratosphere to breathe.
True
What are shooting stars?
Meteors burning up in the mesosphere.
Why do temperatures reach up to almost 3,700 degrees in thermosphere?
Logical response: It is the hottest layer OR therm means to contain heat OR it is supposed to protect from cold temperatures in outer space.
False: The mesosphere, stratosphere and thermosphere also protect against some of these things.
