Earths Magnetic Field

Mr. Mendoza

Solar Wind and Earth’s Magnetic Field

Solar wind is a supersonic plasma (Remember, that’s charged particles or ions) that flows outward from Sun at high speeds & bathes planets in a flood of high-energy particles. (Which isn’t very good for us!)

What protects us from the deadly solar wind?

Solar Wind and Earth’s Magnetic Field

Earth’s magnetic field protects us from the solar wind by deflecting these particles and trapping them in two huge rings (Van Allen belts).

The Strength of Earth’s Magnetic Field

Our magnetic field is decreasing by 5% a century Jupiter has a super-strong magnetic field What would happen if our magnetic field was much stronger?

Solar Wind and Earth’s Magnetic Field

The auroras are created when 

high-energy particles in Van Allen belts collide with gases in Earth’s atmosphere & give off light

Energy for Photosynthesis

1.During photosynthesis, solar energy is transformed into chemical energy (food).

2.This occurs in plants, algae & some bacteria.

Energy for photosynthesis

3.For this to occur, there must be water, CO2,

4.Energy source: sunlight.

5.In plants, this occurs in chloroplasts.
