Troposphere
what does trop mean
turning
what does meso mean?
middle
How do humans affect the thermosphere?
Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities
what is the exact temp of the stratosphere?
-60%
what does the exosphere protect us from
The exosphere primarily protects the Earth by absorbing some of the most harmful radiation from the sun.
is it below or above the equator
above
how does mesosphere protect life???
the mesosphere helps protect the earth from meteors.
is the thermosphere stable or unstable
fairly steady
which layer is the stratosphere a part of?
2 layer
what would happen if we didn't have the exosphere
The exosphere primarily protects the Earth by absorbing some of the most harmful radiation from the sun.
it is the hightes layers of the atmosphere is that true or false
false
who discovered the mesosphere
Albert Einstein
why is it hard to breathe in the thermosphere
The “thin” air at high altitudes has considerably less oxygen and pressure.
is the stratosphere warmer or colder than the bottom layer
warmer
what is the exosphere made of?
The exosphere layer is mainly composed of extremely low densities of hydrogen, helium and several heavier molecules including nitrogen, oxygen, and carbon dioxide closer to the exobase.
what would happen if troposphere was not there
the air would be too then to breathe
why is the mesosphere cold
Carbon dioxide in the mesosphere also helps make this layer cold
what makes the thermosphere hot
incoming high energy ultraviolet and x-ray radiation from the sun begins to be absorbed by the molecules in this layer and causes a large temperature increase
what does the stratosphere protect us from
harmful ultraviolet (UV) radiation and is therefore often called 'good' ozone.
what makes the exosphere special??
it absorbs the ultraviolet radiations and protects the layers underneath.
does the troposphere support life
the atmospheric layer that supports life is called troposphere
Does the mesosphere absorb heat
there is little matter to absorb the Sun's rays and heat the air. Most of the heat that enters the mesosphere comes from the stratosphere below.
what happenes when you go higher in the thermosphere
raising its temperature to hundreds or at times thousands of degrees
what would happen if the stratosphere was destroyed
The breakdown of the ozone layer increases skin cancer and cataracts in humans, impairs immune systems of all animals (including humans), and interferes with phytoplankton productivity in the oceans.
can humans breathe in the exosphere
there is no air to breathe, and it's very cold.
