Our Atmosphere

1. The atmospheric layer closest to the Earth where weather happens.

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere

2. The atmospheric layer that is the coldest. Meteors burn up in this layer.

5. The protective layer in the atmosphere that protects Earth from ultraviolet radiation

• Greenhouse gases
• Greenhouse effect
• Climate Change
• Ozone Layer
• Chloroflourocarbons

6. A natural situation in which heat is retained in Earth's atmosphere due to certain gases. It makes it so Earth is warm enough for life.
