False

OUTER MOST LAYER that might still contain some atmosphere of earth, but only the lightest gases, such as hydrogen and helium, can be found here.

Exosphere

COLD air is LESS dense than hot air

False

This layer gets colder with altitude and is the coldest layer.

Mesosphere

layer is the THICKEST layer in terms of distance, warms up with altitude and where the space shuttle orbits.

Thermosphere

This layer has 80% of the air in the atmosphere, is the most dense layer and contains clouds

Troposhere

Respiration or breathing is taking IN oxygen and breathing OUT carbon dioxide.

True

Hot air has LESS kinetic energy than cold air

false

This layer contains the ozone layer and gets warmer with altitude. This layer stops 100% of UVC, 95% UVB and 5% of UVA.
