The Atmosphere

The composition of the atmosphere is mostly nitrogen.

The atmosphere is a mixture of gases that surrounds Earth

Bradley Nye the science guy here, lets talk science.

The measure of the force with which air molecules push on a surface is call air pressure.

The greenhouse effect is the process by which gas in the atmosphere absorb and reradiate heat.

The three types of gases in the atmosphere nitrogen, oxygen, carbon dioxide.

Stratosphere is the layer of the atmosphere contains the ozone layer

In the Mesosphere metros burn up before hitting the land on the troposphere .

The troposphere is the layer of the atmosphere that contains almost 80% of the atmosphere's total mass.

Another term for air movement cause by difference in air pressure is wind.

The apparent curbing of winds due to Earth's rotations is the Coriolis Effect. Without the Coriolis effect winds would blow north and south only.

Pilots often take advantage of the jet streams, which are high speed winds between 7km and 16km above Earth's Surface.

The uneven heating of the Earth's surface by the sun cause differences in air temperature and density causes wind.

Cool air sinks, causing an area of high air pressure.

A measure of the amount of water vapor in the air is called humidity.

Conduction is the type of heat transferred due to direct contact.
