16.3 Solar Activity

By: Jackson Germond

Include

This smore will include 8 things. Those 8 things are a title page/image of the sun, an image of all the sun's layers, images of each of the following layers/explanations of their properties. The layers are core, radiative zone, convective zone, photosphere, chrome sphere, and corona. This smore will also include and image/explanation of sunspots. An image/explanation of a prominence. An image/explanation of a flare. And finally, an image/explanation of an aurora.

Layers of the Sun

Big image

Core

The center of the sun where nuclear reactions consume hydrogen in order to form helium. The temperature here is approximately 27,000,000 degrees Fahrenheit
Big image

Radiative Zone

The radiative zone is the area between the core and the convective zone. In the radiative zone energy is created by nuclear fusion.
Big image

Convective Zone

The region between the radiative zone and the photosphere. Area where energy is transferred by convection. In this area the hot plasma rises, cools down as it gets closer to the surface, and falls to heat up and rise again.
Big image

Photosphere

The surface of the sun. The Photosphere looks solid but is actually just a very thick gas.
Big image

Chromosphere

The chromosphere is the second of the three main layers and is 2,000 kilometers deep. The chromosphere is nearly always invisible but can be seen during a total eclipse.
Big image

Corona

An aura of plasma that surrounds the sun. This is only visible during a total solar eclipse.
Big image

Sunspots

A sunspot is a spot on the sun that appears darker than the rest.
Big image

Prominence

A large bright gaseous feature going away from the sun's surface in a loop shape.
Big image

Flares

A solar flare is a flash of brightness near the surface of the sun. It releases the equivalent of 160,000,000,000 megatons of TNT.
Big image

Aurora

An aurora is a geomagnetic storm. This is a kind of space weather even that occurs when the magnetic fields around Earth are released.
