THE TROPOSPHERE IS THE LOWEST LAYER IN THE ATMOSPHERE. THIS LAYER IS PRIMARILY COMPOSED OF nitrogen and oxygen

THE TROPOSPHERE IS 78% NITROGEN AND 21% OXYGEN. THE OTHER 1% IS ARGON WATER VAPOR AND CARBON-DIOXIDE.

THE STRATOSPHERE IS THE SECOND LOWEST LAYER OF THE ATMOSPHERE. IT IS ALSO MAINLY MADE UP OF NITROGEN AND OXYGEN.

THE STRATOSPHERE CONTAINS OZONE. IT IS 99% OXYGEN AND NITROGEN. THE OTHER 1% IS TRACE GASES.

THE OZONE LAYER IS THE LAYER OF THE ATMOSPHERE THAT PROTECTS US FROM THE SUN'S RAYS.

THE MESOSPHERE IS THE THIRD HIGHEST LAYER OF THE ATMOSPHERE. IT CAN REACH UP TO -130 DEGREES FAHRENHEIT.

MOST METEORS THE ENTER THE EARTH USUALLY BURN UP IN THIS LAYER. THE MESOSPHERE IS MAINLY MADE OF OXYGEN AND NITROGEN.

THE THERMOSPHERE IS THE 2 HIGHEST LAYER OF THE ATMOSPHERE. THIS LAYER CAN GET AS HOT AS 2,600 DEGREES FAHRENHEIT.

THE INTERNATIONAL SPACE STATION ORBITS AROUND IN THE TROPOSPHERE. THERE IS NITROGEN HERE, AND THERE IS LESS OXYGEN.

THE EXOSPHERE IS THE OUTERMOST LAYER OF THE ATMOSPHERE. THIS LAYER IS MAINLY COMPOSED HYDROGEN AND HELIUM.

THE EXOSPHERE HAS LOW DENSITY. THE TEMPERATURE DEPENDS ON THE MOLECULES. IF THE MOLECULES ARE SLOW IT IS COLD.
