The Sun and Us
The Sun’s Energy
The Sun’s EnergyEnergy leaves the sun in the form of heat and electromagnetic radiationResult from the fusion reactions in the sun
The Sun’s EnergyFission – 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 EnergyIn form of Electromagnetic Energy Waves
Energy absorbed or radiated by particlesInclude x-rays, gamma rays, visible light, etcLots of it may be harmful to life
Sun’s EnergyLots of harmful radiation absorbed or reflected by atmosphereEarth’s magnetism also reflects radiation
Solar EnergySome radiation gets through
Visible light spectrum
Sun’s EnergySolar energy that reaches Earth’s surface is…
Turned into chemical energy by process called photosynthesis
Leads to our own energy
Earth’s EnergySolar energy that reaches Earth’s surface is…
Reflected/absorbed by land and waterTakes LOTS of energy to heat up water
Why do you think this is important?
