traps energy from the ? keeping the Earth warm and water in ? state
protects Earth from dangerous ? and ? collisions

Answer 2

traps energy from the sun keeping the Earth warm and water in liquid form
protects Earth from dangerous radiation and meteor collisions

Question 3

atmospheres are divided into layers according to ? changes with altitude.

Answer 3

atmospheres are divided into layers according to temperature changes with altitude.

Question 4

Troposphere – layer closest to Earth’s surface which extends from the surface to altitudes of ? km; layer in which Earth’s ? occurs.

Answer 4

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.

Question 5

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.

Answer 5

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.

Question 6

Mesosphere – beginning at ? km and ending around ? km

protects Earth’s surface from being hit by most?-which burn up from ?

Answer 6

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

Question 7

Thermosphere – 8?km, contains the ionosphere contains ions, or ? particles allowing ? waves to bounce off and ? to occur.
