Energy Nuclear Fusion, Nuclear Fission, Combustion and Solar Radiation.

Fission and Fusion are both nuclear reactions that involve the particles in the nucleus of an atom.

Forms of Energy Potential or Kinetic. All forms of energy fall under two categories Potential: Stored energy Energy of position Chemical Nuclear Stored.

MEASURING RADIATION Large doses of radiation are harmful to living tissue. Radiation can be measured with a Geiger counter – a device that measures radioactivity.

The Sun Energy from the Sun (Fusion) Energy from the sun is called solar energy. Solar energy is the solar radiation that reaches the earth. Energy.

Fission and Fusion. Nuclear Reactions Two types of nuclear reactions that release energy.  Fission  Fusion.

The Sun and Us 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?
