2. In the darkest regions of deep space, the temperature is a chilly -450° Fahrenheit.
3. In the darkest regions of deep space, the temperature is a chilly -450° Fahrenheit. Closer to our Sun, temperatures reach thousands of degrees Fahrenheit.
4. All planets have an atmosphere, a layer of gases that surrounds them.
6. Earth's is made up primarily of nitrogen and oxygen, carbon dioxide, ozone, and other gases are also present. The Sun's atmosphere is made up of hydrogen.
7. These gases keep our planet warm and protect us from the direct effects of the Sun's radiation.
8. These gases keep our planet warm and protect us from the direct effects of the Sun's radiation. Without this regulation, Earth could not sustain life.
9. The atmosphere is made up of several layers: the Troposphere , Stratosphere , Mesosphere , Ionosphere , and Exosphere .
11. T roposphere 10 miles Most of the clouds you see in the sky are found in the troposphere, and this is the layer of the atmosphere we associate with weather.
13. T roposphere S tratosphere 10 miles 3 0 miles Includes the ozone layer. Ozone molecules, which are concentrated in this layer, absorb ultraviolet radiation from the Sun and protect us from its harmful effects.
