|
Radio |
Low Energy and Frequency High Wavelengths |
|
|
Visible Light |
400 - 800 nanometers 400=short wavelength 800=long wavelength |
|
|
Atoms that have gained or lost an electron and have a net charge are called |
Ions |
|
|
Absorption of a photon |
Jumps to a higher energy level |
|
|
Emission of a photon |
Jumps to a lower energy level |
|
|
Absorption line spectrum |
Rainbow background, black lines |
|
|
Blue Shifted |
an object is moving towards us (shorter wavelengths) |
|
|
Red Shifted |
Object is moving away from us (Longer wavelengths) |
|
|
Earths Twin |
Venus |
|
|
My Very Excellent Mom Just Served Us Noodles |
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune |
|
|
The belt after the terrestrial planets |
Asteroid Belt |
|
|
The belt after the Jovian planets |
Kuiper Belt |
|
|
Oort Cloud |
waaaaay past the Kuiper Belt. Most comets come from the Oort Cloud |
|
|
The biggest rocky planet and the biggest gas planet |
Earth, Jupiter |
|
|
All planets orbit the sun |
Counter clockwise |
|
|
Nebula |
A cloud of gas and dust |
|
|
Bigger Axis Tilt |
More dramatic seasons |
|
|
The frost line is how many AU from our solar system |
5 AU |
|
|
Radioactive Decay |
an unstable atomic nucleus loses energy by radiation |
|
|
Nuclear Fusion |
Nuclear fusion is a reaction in which two or more atomic nuclei combine to form different atomic nuclei and subatomic particles. |
|
|
Order of Sun Layers Charming Rabbits Celebrate Parties, Carrots, and Cuddles! |
1. Core -energy is generated here 2. Radiative zone 3. Convective zone 4. Photosphere 5. Chromosphere 6. Corona |
|
|
Fission |
Large nucleus splits into daughter particles |
|
|
Solar Thermostat |
Self regulating temperature mechanism of the sun. Temp rises-nuclear reactions increase-energy output increases-outer layers expand and core temperature drops |
|
|
Accretion: |
Objects collide converting gravitational energy to kinetic energy then to thermal energy |
|
|
Differentiation: |
Denser materials sink to the core and the same energy conversion takes place as with accretion |
|
|
Radioactivity |
isotopes inside the planet decay into more stable elements releasing thermal energy |
|
|
Convection |
Hot rock rises and cooler rock falls |
|
|
Conduction |
Heat transfers from the warm mantle through the lithosphere to the surface |
|
|
Radiation |
Surface emits IR radiation into space |
