Study Notes
Earth's Atmosphere
- Earth's atmosphere is a layer of gases that surrounds the planet, providing warmth, oxygen, and facilitating weather.
- The atmosphere was formed from gases emitted by volcanoes.
- The atmosphere consists of five layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.
Troposphere
- Extends 20 km from the Earth's crust.
- Temperature decreases with altitude.
Stratosphere
- Contains ozone, which absorbs ultra-violet light, protecting the Earth.
- Temperature increases with altitude.
Mesosphere
- Contains no water vapor, clouds, or dust particles.
- Temperature decreases with altitude.
Thermosphere
- Contains atomic oxygen, which absorbs ultra-violet light, protecting the Earth.
- Temperature increases with altitude, exceeding 1500°C.
Exosphere
- The outermost layer of the Earth's atmosphere, considered part of outer space.
- No upper limit to the Exosphere.
Hydrosphere
- The total amount of water on a planet, including surface, underground, and atmospheric water.
- Can exist as liquid, vapor, or ice.
- On Earth, liquid water exists in oceans, lakes, and rivers.
Rocks
- A natural substance composed of solid crystals of different minerals fused together.
- Studied by geologists.
- Rocks and minerals are abundant in our daily lives.
