Earth’s Atmospheric Layers

Question 1

Layers of the Atmosphere (TSMTE - the silly monkey trills endlessly)

Answer 1

Trophosphere
Stratosphere
Mesosphere
Thermosphere
Exosphere

Question 2

Trophosphere (extends 11km above Earth)

Answer 2

Closest to Earth. All weather occurs here

Most dense layer

80% of the atmosphere’s mass ( has most of the air)

Question 3

Stratosphere (extends 50km above Earth)

Answer 3

Contains most of the ozone layer

Free of weather and clouds

As the altitude increases the temperature increases because of the ozone layer

Question 4

Mesosphere (extends 80 km above Earths surface)

Answer 4

The coldest layer

Most likely to have meteors

Question 5

Thermosphere

Answer 5

Closest to the sun so it is the hottest layer

Auroras are here

The International Space Station (ISS) is here

Question 6

Exosphere

Answer 6

Thin layer but the largest layer
Very cold
Space is located here
Has the lowest pressure and is the least dense

Question 7

Gases in the atmosphere

Answer 7

Oxygen 21%
Nitrogen 70%
Other gases 1%
