Answer 9

Nitrogen (78%)
Oxygen (21%)
Argon (0.93%)
Carbon dioxide (0.04%)
Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor

Question 9

Mixture of gases that surrounds the planet.

Answer 9

atmosphere

Question 10

starts at the Earth’s surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region

Answer 10

troposphere

Question 11

starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer.

Answer 11

The stratosphere

Question 12

starts just above the stratosphere and extends to 85 kilometers (53 miles) high. Meteors burn up in this layer.

Answer 12

The mesosphere

Question 13

starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.

Answer 13

The thermosphere

Question 14

an abundant layer of electrons and ionized atoms and molecules that stretches from about 48 kilometers (30 miles) above the surface to the edge of space at about 965 km (600 mi), overlapping into the mesosphere and thermosphere

Answer 14

ionosphere

Question 15

critical link in the chain of Sun-Earth interactions. This region is what makes radio communications possible.

Answer 15

ionosphere

Question 16

This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km (6,200 mi).

Answer 16

Exosphere

Question 17

Refers to solid Earth.

Composed of all the rocks, minerals, and soil on Earth.

Includes not only the mountains, continents, ocean floor, sand in the deserts, and bedrocks but it also includes Earth’s interior layers

Answer 17

geosphere

Question 18

refers to the solid and rigid outer layer that includes the crust and the uppermost part of the mantle.

Answer 18

LITHOSPHERE

Question 19

below lithosphere which consists of the solid but mobile part of the mantle that can flow depending on the heat deep within Earth.

Answer 19

ASTHENOSPHERE

Question 20

Made up of all the living organisms on the planet.

These living things are found on the surface, underground, and even those reaching a kilometre above the surface of the Earth.

It includes the plants, animals, bacteria, and fungi that thrive on the planet even in the most extreme environments in the depths and corners of Earth.

Answer 20

biosphere
