Transcript of The Atmosphere
An Atmospheric Intro
The troposphere is the first layer of the atmosphere.
Soon following is the Stratosphere.
Next, the Mesosphere lies just before the Thermosphere.
The Exosphere is the final layer of the Earths atmosphere.
The Exosphere Is also know as "space". Exo- means external, or from outside.
A layer of the atmosphere just above the troposphere and just below the mesosphere
31 miles above the earth's surface.
Ozone, an unusual type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the Sun. Temperatures rise as one moves upward through the stratosphere. This is exactly the opposite of the behavior in the troposphere.
The Mesosphere is the third layer from the earth’s surface.
The Exosphere is 311 miles from earth
It starts right where the Thermosphere ends
The 5th and highest level of the Atmosphere
This layer is so high a plane cannot fly through it
Made up of Hydrogen and Helium
The Exosphere is only made up of gases
It is the thinnest layer of the atmosphere
It is so thin, atoms bounce off and land in space
The layer is very hot, though can feel -12 degrees
The atmosphere grows thin, though this layer weighs hundreds of tons
No one can live in this layer because the lack of oxygen
and Rich B.
The Thermosphere is the layer of the Earth's atmosphere directly above the mesosphere and directly below the exosphere.
Within this layer, ultraviolet radiation(UV) causes ionization.
The Thermosphere is 85-500 kilometres above the earth's surface.
The mesopause, at an altitude of 80–90 km (50–56 mi), separates the Mesosphere from the Thermosphere.
The Troposphere Is the first layer in the Atmosphere.
The temperature of the troposphere generally decreases as altitude increases. The temperature goes from 15 degrees to -55 degrees C.
The air pressure at the top of the troposphere is only 10% of that at sea level.
More on the Exosphere
Related Terms and Vocabulary
This layer has a lack of gravity
The layer is so thin, there is
barely any gravity or air pressure
This layer protects us from the
harmful rays of the sun
There is close to 5 billion tons
of air in atmosphere
This layer is related to solar
and lunar radiation
The lower you get, the more
air pressure there is.
Additional facts about of the Thermosphere
It is located 80 KM/49.7 ml up form the earth surface. It is above the Stratosphere and below the Thermosphere.
The composition includes planetary and gravity waves, winds, and atmospheric tides.
Here temperature decreases with altitude, going to as low as -100 degrees centigrade. Very strong winds exists at this altitude.
It is the coldest layer of the atmosphere. As in the troposphere, the temperature drops as low as -93c at the top of the mesosphere.
Scientist have recently discovered large windstorms in the mesosphere with winds up to more than 320 KM/H.
. It is located between the mesosphere and the exosphere which make up the ionosphere and ranges from 80 to 10,000 km above sea level.
The biggest layer in our atmosphere, the Space shuttle is the only object that makes it up in the layer, the air is very thin and small amount of energy can cause a large change in temperatures.
The layer of the earth's atmosphere that contains a high concentration of ions and free electrons and is able to reflect radio waves.
It lies above the mesosphere and extends from about 50 to 600 miles (80 to 1,000 km) above the earth's surface.
the envelope of gases surrounding the earth or another planet.
A storm is any disturbed state of an astronomical body's atmosphere especially affecting its surface, and strongly implying severe weather.
of or denoting a scale of temperature in which water freezes at 0° and boils at 100° under standard conditions
the degree or intensity of heat present in a substance or object, esp. as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
atmospheric pressure: the pressure exerted by the atmosphere
The tropopause is the boundary region between the troposphere and the stratosphere.
The Stratopause is the barrier between the Stratosphere and the Mesophere.
