Flora - SOL Review D
SOL Review D Astronomy
| Question | Answer |
|---|---|
| Mercury | planet closest to the Sun; therefore, it orbits the Sun the fastest |
| Venus | this planet has a thick atmosphere of carbon dioxide which creates a greenhouse effect that causes suface temperatures to be very high, called Earth's twin |
| Mars | called the red planet, thin atmosphere, huge volcano called Olympus Mons and a huge canyonn called Valles Marineris |
| Jupiter | largest planet with a hurricane-like giant storm called the Great Red Spot, has the most moons of any planet |
| Saturn | the planet with beautiful rings, would float in water |
| Uranus | this planet rotates on its side because its axis lies nearly parallel with the plane of its orbit |
| Neptune | this bluish planet is one of windiest places in the Solar System and has the distinction of not sometimes being the farthest planet from the Sun |
| Big Bang | the Theory that the universe originated as a single mass, which exploded and everything is still expanding |
| nebula | a cloud of gas and dust from which stars form |
| comet | a frozen mixture of frozen gases and rocks which orbit the Sun, the solar wind causes its tail to always point away from the Sun, its path around the Sun is very elliptical |
| meteor | small solid particles from space that travel through Earth's atmosphere and burn, producing a streak of light |
| asteroid | a rocky object generally located in a belt between Mars and Jupiter |
| fusion | (blank) |
| photosphere | the Sun's layer from which all light comes |
| sunspot | a dark spot on the sun's surface that is cooler than the surrounding area, Galileo studied these |
| corona | the outer layer of the Sun's atmosphere which we can see only during a solar eclipse |
| apparent | type of magnitude which describes the brightness of a star when viewed from Earth |
| absolute | the type of magnitude used to measure how bright the star actually is |
| summer | this season occurs in the Northern Hemisphere when the Earth's axis is tilted toward the Sun |
| winter | this season occurs in the Northern Hemisphere when the Earth's axis is tilted away from the Sun |
| red | type of doppler shift that indicates an object is moving away from Earth (also indicates universe is expanding) |
| blue | type of doppler shift that indicates an object is moving toward Earth |
| solar wind | streams of protons & electrons ejected at high speed from the sun's corona (makes comet's tail always point away from Sun) |
| light year | the distance light travels in one year |
