STRUCTURE OF THE ATMOSPHERE
TEMP IN THE ATMOSPHERE
the temp in the atmosphere is not consistent
the temp changes according to height
when it change with height it is called TEMP GRADIENT
1 IS THE TROPOSPHERE
is the bottom layer of the atmosphere
weather occurs in troposphere
plants and animals live in the troposphere
precipitation and all other weathering occurs
contains more than 70% of the mass of the atmosphere
2 IS THE STRATOSPHERE
is above the troposphere
jets and some aircrafts can fly in the stratosphere
it is safer to fly in the stratosphere
THE OZONE LAYER
the stratosphere is made up of ozone gas
ozone is an invisible gas
it forms a layer around the earth
it absorbs high energy
there is ultraviolet radiation
ultraviolet radiation is radiation that has a shorter wavelength than the violet light of the visible spectrum
3 THE MESOSPHERE
ABOVE THE STRATOSPHERE
is very thin and cold
temp can drop to -100
meteors are found in the mesosphere
a meteor is a that goes through the earths atmosphere from space
a meteor travels at high speeds
air becomes hot and the meteor combusts because of the heat and friction
largest meteor is found in Namibia
4 THE THERMOSPHERE
is the most dense layer in the atmosphere
the temp increases from -90 to 1500 degrees
it is sensitive
the INTER NATIONAL SPACE STATION (ISS) is in an orbit around the earth
weather , television and communication satellites use the thermosphere to send info to earth
there are POLO LIGHTS which are visible in the thermosphere
