Question

5 label each layer of earths atmosphere with its description.

extremely high temperatures hurricanes form gases escape into space meteors disintegrate
uv rays are absorbed

6 why is the top of the stratosphere warmer than the bottom?
a there is an increase in carbon dioxide levels
b there is a decrease in air pressure
c the suns light heats it from above
d ocean water draws down heat

Explanation:

Question 5 (Labeling Atmosphere Layers)

Step1: Identify the outermost layer (Exosphere)

The outermost layer of the atmosphere is the exosphere, where gases escape into space. So the topmost label should be "Gases escape into space".

Step2: Next layer (Thermosphere)

The thermosphere has extremely high temperatures (due to absorption of high - energy solar radiation) and is also where meteors disintegrate. So the next label (second from top) can be "Extremely high temperatures" or "Meteors disintegrate". Let's take "Extremely high temperatures" first.

Step3: Middle - upper layer (Mesosphere)

The mesosphere is where meteors disintegrate. So if we used "Extremely high temperatures" for thermosphere, now for mesosphere, it's "Meteors disintegrate".

Step4: Middle - lower layer (Stratosphere)

The stratosphere is where UV rays are absorbed (by ozone). So this layer's label is "UV rays are absorbed".

Step5: Lowest layer (Troposphere)

The troposphere is where weather phenomena like hurricanes form. So the bottom - most label is "Hurricanes form".

Question 6 (Why stratosphere top is warmer)

Step1: Analyze Option A

Carbon dioxide increase is more related to greenhouse effect in troposphere, not stratosphere heating. Eliminate A.

Step2: Analyze Option B

Air pressure decrease with altitude, but pressure change doesn't directly cause heating in stratosphere. Eliminate B.

Step3: Analyze Option C

The stratosphere has ozone that absorbs UV rays from the Sun. The absorption of UV rays (which come from above) heats the stratosphere, so the top (closer to the source of UV after ozone absorption) is warmer. This is correct.

Step4: Analyze Option D

Ocean water doesn't draw down heat to stratosphere. Stratosphere is above troposphere, and ocean - heat interaction is in troposphere. Eliminate D.

Question 5 Answer (Layer - Label Pairing from top to bottom):

1. Gases escape into space (Exosphere)
2. Extremely high temperatures (Thermosphere)
3. Meteors disintegrate (Mesosphere)
4. UV rays are absorbed (Stratosphere)
5. Hurricanes form (Troposphere)

Question 6 Answer:

C. The Sun's light heats it from above

Answer:

Step1: Analyze Option A

Carbon dioxide increase is more related to greenhouse effect in troposphere, not stratosphere heating. Eliminate A.

Step2: Analyze Option B

Air pressure decrease with altitude, but pressure change doesn't directly cause heating in stratosphere. Eliminate B.

Step3: Analyze Option C

The stratosphere has ozone that absorbs UV rays from the Sun. The absorption of UV rays (which come from above) heats the stratosphere, so the top (closer to the source of UV after ozone absorption) is warmer. This is correct.

Step4: Analyze Option D

Ocean water doesn't draw down heat to stratosphere. Stratosphere is above troposphere, and ocean - heat interaction is in troposphere. Eliminate D.
