Study
| Term | Definition |
|---|---|
| Types Of Waves In The Electromagnetic Spectrum From Farthest Apart To Closest Together | Radio, Microwave, Infrared, Visible, Ultraviolet, X-Ray, Gamma Ray |
| Irregular Galaxy | System of millions or billions of stars held together by gas and dust. It's held together by gravity |
| Nuclear Fusion | Atoms fuse together in the core of the sun because of tremendous heat and gravity. It creates energy and radiation. |
| Star Size Smallest To Largest | Quark, Neutron, White Dwarf, Medium Size, Giant, Super Giant |
| Star Size Coldest To Hottest | Red, Orange, Yellow, White, Blue |
| Life Cycle Of Sun | Nebula, Protostar, Medium Star, Red Giant, Outer Ring Blows Off, Star Condenses Into White Dwarf and Burns Into Black Dwarf |
| Spectroscope | A device that separates visible light into its component colors |
| Pluto was thought to be a | captured object from the Kuiper belt |
| Newtons 3rd Law | for every action there is an equal and opposite reaction |
| Name All 6 Orbital Theorists | Ptolemy, Copernicus, Galileo, Tycho Brahe, Kepler, Newton |
| Newton | proved elliptical orbits due to inertia and gravity |
| Kuiper Belt | pieces of nebulas that form comet-like objects outside of Pluto's orbit |
| Oort Cloud | sphere of debris surrounding the solar system, also contains comet-like objects |
| Magnetosphere | magnetic field around the earth that protects us from solar and magnetic radiation |
| How was the magnetosphere produced? | Our spinning core translates extra energy to the magnetic field |
| Aurora | Charged particles and plasma from the sun interact with the Van Allen belts and produce light in the gases of the atmosphere |
| 4 types of satellites | Scientific, Navigational, Military, Communication |
| Salt water is _ of the earth's water | 97 |
| Freshwater is _ of earth's water | 3 |
| Groundwater is _ of the earth's water | .6 |
| Drinkable water is _ of the earth's water | .09 |
| How did the atmosphere form? | Hydrogen and Helium went into space, and volcanic outgassing released methane, ammonia, Co2, and Ho2, then the gases are broke down by sunlight |
| How was the ozone created? | Lightning breaks water vapor and C02 and it releases oxygen. This formed the ozone, allowing blue-green algae to grow. Then, the algae photosynthesized and produced oxygen gas. |
| 3 temp zones from coldest to warmest | Surface, Thermocline, Deep Zone |
| Life Zones In The Ocean | Intertidal, Neritic, Open Ocean, and Deep Zone |
| Types Of Frozen Water | Glaciers, Ice Burgs, Ice Caps |
| Watershed | Sloped land that stores/provides water |
| Luminosity of a star depends on | size and temp |
| Ozone layer is found in the | stratosphere |
