THE SUN HAS LAYERS!?

WIKI-WIKI-WHATTTTTT?!?!

NO! not those layers!

These layers!!!

hardCORE! ! ! !

The innermost layer of the sun is the core!

-the core’s temperature is about 27 million degrees Fahrenheit!

-fusion reactions produce energy in the form of gamma rays.

RRRRRadiation ZZZZZone

• It provides efficient transferring of energy near the core

• Hot and dense

CONVECTION

• Thermal columns carry hot material to the surface

• After it cools, it plunges down to the base of the convection zone to obtain more heat from the top.

PHOTOSPHERE!-Visible surface of the sun

-solar atmosphere

-can be seen with telescopes!

Chromosphere

• Thin layer above the visible surface

• Originated from the Greek word chromos

• It means color

Corona!

• The outer atmosphere of the sun

• Larger in volume than the sun itself

• Several million degrees

Energy production

• The sun produces energy through nuclear reactions in which nuclei collide and stick together.

• the nucleus calms down by releasing some energy in the form of a gamma ray, which helps to heat the sun.

Sun spots!

• Appear visibly as dark spots

• temporary phenomena on the photosphere of the Sun

• caused by intense magnetic activity

Effects on Earth

• Warms out planet

• Energy drives much of our weather

• solar cosmic rays affect Earth‘s cloudiness.

The END!!!!
