Question 1) Which gas is the most abundant in Earth’s atmosphere?

A) methane

B) carbon dioxide

C) oxygen

D) nitrogen

Question 2) Particles of air escape into space from which layer of the
atmosphere?

A) troposphere

B) mesosphere

C) thermosphere

D) stratosphere

Question 3) Which atmospheric layer is most dense?

A) stratosphere

B) mesosphere

C) troposphere

D) thermosphere


Question 4) Where do meteorites burn up?

A) stratosphere

B) thermosphere

C) mesosphere

D) troposphere


Question 5) Which layer of the atmosphere is the least dense?

A) troposphere

B) exosphere

C) stratosphere

D) mesosphere

Question 1.

Out of the options I would say Nitrogen is the most abudnats in Earth's atmosphere.

Question 2.

The best answer is the thermosphere, molecules with enough energy can escape through this atmosphere.

Question 3.

The troposphere is the most dense, it's 5 to 9 miles long. Basically every type of weather is in this region.

Question 4.

The mesosphere is where meteorites burn before reaching the surface of Earth.

Question 5.

The exosphere is extremly low, the farther you are away from Earth the lower the density.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
