Question

atmosphere p. 377

2. water vapor p. 378

3. troposphere p. 380

4. stratosphere p.380

5. ozone layer p. 380

6. ionosphere p. 381

‼️EXAMPLE: Scientists are monitoring the ozone layer to ensure it continues to recover from past damage caused by harmful chemicals.

Answer 1

1. atmosphere (p. 377) — The atmosphere is the layer of gases that surrounds Earth, supporting life and helping regulate temperature and weather.

2. water vapor (p. 378) — Water vapor is the gaseous form of water that rises from bodies of water and contributes to cloud formation and weather patterns.

3. troposphere (p. 380) — The troposphere is the lowest layer of Earth’s atmosphere, where nearly all weather occurs and temperature generally decreases with altitude.

4. stratosphere (p. 380) — The stratosphere lies above the troposphere, contains the ozone layer, and has temperatures that increase with altitude due to absorption of ultraviolet radiation.

5. ozone layer (p. 380) — Scientists are monitoring the ozone layer to ensure it continues to recover from past damage caused by harmful chemicals.

6. ionosphere (p. 381) — The ionosphere is a charged region of the upper atmosphere that affects radio communications and produces phenomena like the auroras.
