and thinner at night.
The following image shows the five layers of Earth's atmosphere. (The image is not drawn to scale.)
Which of the following statements is most likely correct? - ANSWER-Point E is about 190,000 km above
Earth's surface, and Point A is about 12 km above Earth's surface.
How do auroras form? - ANSWER-Auroras form when solar flare activity interacts with the charged
particles in the ionosphere.

A satellite is orbiting Earth at an altitude of 50,000 km. In which layer of the atmosphere is the satellite
located? - ANSWER-exosphere

The following image shows the five layers of Earth's atmosphere. (The image is not drawn to scale.)
Which of the following statements is correct?
E
D
C
B
A - ANSWER-Temperature both increases and decreases below layer D, then increases steadily above
layer D.
Which layer of the atmosphere is the coldest? - ANSWER-mesosphere
Which of the following statements most accurately compares and contrasts the different layers of Earth's
atmosphere? - ANSWER-In the troposphere and mesosphere, temperatures steadily decrease with
altitude, whereas in the stratosphere and thermosphere, temperatures steadily increase with altitude.
The following image shows the five layers of Earth's atmosphere. (The image is not drawn to scale.)
Which of the following statements is correct?
e
d
c
b
a - ANSWER-Temperature decreases steadily in layer C (moving from bottom to top), then increases
steadily in layer D (moving from bottom to top).
,In the troposphere, temperature - ANSWER-decreases steadily with increasing altitude
In the stratosphere, temperature - ANSWER-increases steadily with increasing altitude
Which of the following best explains the relationship between temperature and altitude in the
troposphere? - ANSWER-In the troposphere, air is warmed primarily by Earth's surface; therefore, higher
regions of the troposphere are cooler than lower regions.
A meteor is passing above Earth at an altitude of 70 km. In which layer of the atmosphere is the meteor
located? - ANSWER-A meteor is passing above Earth at an altitude of 70 km. In which layer of the
atmosphere is the meteor located?

which layer do temperatures fall to -80°?
E
D
C
B
A - ANSWER-C
In the thermosphere, temperature - ANSWER-increases steadily with increasing altitude
How do auroras form? - ANSWER-Auroras form when solar flare activity interacts with the charged
particles in the ionosphere.

Which two layers are NOT divided by a boundary, on one side of which temperatures increase, and on
the other side of which temperatures decrease?
E
D
C
, B
A - ANSWER-D and E
The uppermost layer of Earth's atmosphere is the - ANSWER-exosphere
Which of the following best explains the relationship between temperature and altitude in the
mesosphere? - ANSWER-The mesosphere is warmed primarily by heat that moves up from the
stratosphere; therefore, higher regions of the mesosphere are cooler than lower regions.
The stratopause separates which two layers of the atmosphere? - ANSWER-the stratosphere and
mesosphere
Approximately what is the thickness of the ionosphere? - ANSWER-from 50 to 1,000 km above the
planet's surface
Which of the following best explains the relationship between temperature and altitude in the
thermosphere? - ANSWER-In the thermosphere, air is warmed primarily by solar radiation from space;
therefore, higher regions of the thermosphere are warmer than lower regions.
Which layer of the atmosphere experiences the highest temperatures? - ANSWER-thermosphere
Which of the following best explains the relationship between temperature and altitude in the
stratosphere? - ANSWER-In the stratosphere, air is warmed as solar radiation is absorbed by ozone;
therefore, higher regions of the stratosphere are warmer than lower regions.
Which of the following happen(s) most frequently in the troposphere? - ANSWER-weather
Ozone is a molecule composed of - ANSWER-three oxygen atoms
