2. Sun Controls Earth’s Climate System

3. Earth has a global climate system that includes air, land, liquid water, ice, and living things.climate system The climate system is powered by energy from the Sun. The Sun emits different types of radiation: ultraviolet radiation visible light infrared radiation Earth’s Climate System

4. When radiation strikes a particle, it can: 1.get absorbed by the particle, causing particle to gain energy 2.be transmitted through the particle 3.be reflected off the particle Sun’s Radiation:  30% is reflected back to space by clouds and surface of Earth  70% is absorbed by surface, clouds and atmosphere Earth Absorbs Sun’s Energy

5. Earth’s Energy Balance

6.  when Earth’s surface warms, it emits radiation back  the amount of energy Earth’s system absorbs from the Sun equals the amount of energy radiated by Earth’s system  therefore, Earth’s global temperature stays balanced Balance of Energy on Earth
