The Sun
Earth's main source of heat, seasons and more
The sun (brief description)
The sun is a massive ball of heat located in the center of our solar system. The sun causes seasons and weather all over the globe. The sun provides a habitable planet for humans because the planet is neither too close or too far from the sun.
Layers of the sun
The sun has 6 layers. The core, chromosphere, radiation zone, convection zone, photo sphere, and the corona.
The core
In the center of the sun there is the core the core of the sun is the most hot part of it. The temperature is about 15.8 million kelvin, which is a lot of heat.
The Chromoshpere
The suns chromosphere is the outermost layer of the sun. It is the view able part that you see when there is a solar eclipse (as seen in image).
The radiation zone
The radiation zone is the second layer (going in from surface) of the sun. The radiation zone is where all nuclear energy is made from fusion and where all the suns heat and energy comes from.
The convection zone
The suns convection zone is the first 200,000 kilometers of the suns surface. It is where the heat and light is "made." It is the first layer of the suns surface.
The photosphere
The photosphere is the visible part of the sun that we see when we look at it. It is the layer where sunspots (cooled areas) occur and is 100 kilometers thick.
What occurs on the sun
Sunspots
Sunspots are a temporary cooling on the photosphere of the sun that appear visibly as dark spots beside the places around it.
Prominence
A prominence is a large bright feature that shoots out from the Sun's surface, often looping back towards the sun.
Flare
A solar flare occurs when the sun builds up a lot of energy and spontaneously shoots it out into space. A large enough solar flare at earth could mess up the magnetic field. As you can see in the image, a solar flare can be massive compared to Earth
