Prominence-
Sunspots- areas on the Sun’s surface that are cooler than the surrounding area. Sunspots fade, and new ones develop over time.
Solar flare- solar storm which extends into space
Corona- means “crown”, extremely hot area around the Sun’s surface.

4. The Sun
-The Sun is the star at the center of our Solar System (only star in our solar system)
-Made of Hydrogen and helium gases.
-Sun could hold 1,000,000 Earths inside.
-The Sun’s enormous mass creates enough gravity to pull in orbit the planets
-The Sun’s mass also creates tremendous heat
-The Sun has six layers: Core,
- Radiative Zone, Convective Zone, Photosphere, Chromosphere, and Corona.

Has little to no atmosphere
Its made of rocks
Has landforms such as mountains, craters
and valleys
No liquid water
Less gravity than the Sun and the Earth
Causes tides on Earth (4)
