the atmosphere Flashcards
atmosphere – thin layer of ? surrounding ?
made up of ? (78%), ? (21%), carbon dioxide, water vapor, and other gases, as well as particles of liquids and solids.
atmosphere – thin layer of gases surrounding Earth;
made up of nitrogen (78%), oxygen (21%), carbon dioxide, water vapor, and other gases, as well as particles of liquids and solids.
traps energy from the ? keeping the Earth warm and water in ? state
protects Earth from dangerous ? and ? collisions
traps energy from the sun keeping the Earth warm and water in liquid form
protects Earth from dangerous radiation and meteor collisions
atmospheres are divided into layers according to ? changes with altitude.
atmospheres are divided into layers according to temperature changes with altitude.
Troposphere – layer closest to Earth’s surface which extends from the surface to altitudes of ? km; layer in which Earth’s ? occurs.
Troposphere – layer closest to Earth’s surface which extends from the surface to altitudes of 8-12 km; layer in which Earth’s weather occurs.
Stratosphere – layer directly above troposphere, extends from ? km.
Contains the ? layer which protects Earth from ? rays
Human’s use of ？s was depleting the ozone layer.
Stratosphere – layer directly above troposphere, extends from 12km- 50 km.
Contains the ozone layer O₃ which protects Earth from ultraviolet (UV) rays
Human’s use of CFCs was depleting the ozone layer.
Mesosphere – beginning at ? km and ending around ? km
protects Earth’s surface from being hit by most?-which burn up from ?
Mesosphere – beginning at 50 km and ending around 80 km
protects Earth’s surface from being hit by most meteoroids-which burn up from friction
Thermosphere – 8?km, contains the ionosphere contains ions, or ? particles allowing ? waves to bounce off and ? to occur.
The thermosphere is home to the? Station.
Thermosphere – 80 km-800km, contains the ionosphere contains ions, or charged particles allowing radio waves to bounce off and auroras to occur.
The thermosphere is home to the International Space Station.
Exosphere –the top layer of the atmosphere that leads into the vacuum of space.
Air in the exosphere is extremely ? ?. Earth’s ? orbit here.
Exosphere –the top layer of the atmosphere that leads into the vacuum of space.
Air in the exosphere is extremely thin and vey cold. Earth’s satellites orbit here.

air pressure measure of the force with which particles in the air push on an area of a surface.
-the weight of the ? above
