The Sun’s Energy
Energy leaves the sun in the form of heat and
electromagnetic radiation
Result from the fusion reactions in the sun
The Sun’s Energy
Fission – splitting of atoms (nuclear bombs)
Fusion – fusing of nuclei to form heavier
elements (hydrogen to helium)
IMMENSE amts. of energy and neutrons
released
The Sun’s Energy
Sun’s Energy
In form of Electromagnetic Energy Waves
Energy absorbed or radiated by particles
Include x-rays, gamma rays, visible light, etc
Lots of it may be harmful to life
Sun’s Energy
Lots of harmful radiation absorbed or reflected
by atmosphere
Earth’s magnetism also reflects radiation
Solar Energy
Some radiation gets through
Visible light spectrum
Sun’s Energy
Solar energy that reaches Earth’s surface is…
Turned into chemical energy by process called
photosynthesis
Leads to our own energy
Earth’s Energy
Solar energy that reaches
Earth’s surface is…
Reflected/absorbed by
land and water
Takes LOTS of energy to
heat up water
Why do you think this is
important?
