troposphere
The troposphere is, on average, the warmest part of the atmosphere primarily because the atmosphere is heated from the surface.
en invisible water vapor in the air cools and condenses into tiny liquid droplets or ice crystals, which then gather around tiny particles like dust or salt in the atmosphere, essentially forming a visible
Can planes fly in the mesosphere?
We conclude that planes cannot fly in the mesosphere.
What 2 objects are found in the thermosphere?
low Earth orbit satellites.
Is the exosphere very hot?
yes
What is the top layer of the troposphere called?
Tropopause
stratosphere definition
the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).
What will happen if there is no mesosphere?
Without the mesosphere, meteors would pass through the exosphere and thermosphere without much trouble
Is the thermosphere the coldest?
no
How cold can the exosphere get?
0 °C and 1700 °C
What is troposphere easy?
The troposphere is the lowest layer of the Earth's atmosphere in direct contact with the Earth's surface
as the colder air at higher altitudes allows water vapor to directly condense into ice, essentially forming clouds made of tiny frozen particles;
What are two things about the mesosphere?
The atmosphere surrounds the Earth and holds the air we breathe; it protects us from outer space; and holds moisture (clouds), gases, and tiny particles.
Why is the thermosphere layer important?
They absorb high-energy radiation from the Sun that is harmful to humans, thus protecting us.
Does exosphere have very thin air?
yes
Is the troposphere the thickest?
The troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth
from the soil where nitrogen gas from the atmosphere has been converted into a usable form by bacteria through a process called "nitrogen fixation," allowing the plant roots to absorb it as nitrate or ammonium ions.
What does mesosphere protect us?
The mesosphere help protect Earth from meteors,
What can fly in the thermosphere?
satellites
How long does it take to get to the exosphere?
25m
How is the troposphere heated?
sun
The reason for this is that they have just come from deep space, which is cold.
What will happen if there is no mesosphere?
Without the mesosphere, meteors would pass through the exosphere and thermosphere without much trouble.
What lives in the thermosphere?
an occasional meteorite passing through
Is there oxygen in the exosphere?
Yes, there is oxygen in the exosphere, but only in very small amounts as atomic oxygen,
