definitions answer vocabulary words

1. the spinning motion of a planet on its axis h apparent magnitude
2. the movement of an object around another object, ex. the earth moves around the sun a astronomical unit
3. an object that orbits a star, has gravity to be rounded, and has cleared the path of its orbit f dwarf planet
4. a unit of distance equal to the average distance between earth and the sun g light - year
5. an eruption of gas from the suns surface that occurs when the loops in sunspot regions suddenly connect i luminosity
6. an object that orbits the sun, has gravity to be spherical, but has not cleared its orbit c planet
7. a dark area of gas on the suns surface that is cooler than surrounding gases j revolution
8. the brightness a star would have if it were a standard distance from earth (actual brightness) b rotation
9. the distance that light travels in one year g solar flare
10. a stars brightness as seen from earth d sunspot

instructions: carefully read each question before forming your answer. label all pictures. write in complete sentences.

1. draw the geocentric model of the solar system. label the earth and sun.
2. how did the solar system form? include the words: dust, ice, and gravity.

when ice, dust, and other small objects got pulls together by gravity.

1. true or false: the inner planets are cooler than the outer planets.

false false

Explanation:

1. The spinning motion of a planet on its axis is rotation.
2. The movement of an object around another object like Earth around the Sun is revolution.
3. A planet orbits a star, has gravity to be rounded and cleared its orbit path.
4. An astronomical unit is the average distance between Earth and the Sun.
5. A solar - flare is an eruption of gas from the Sun's surface when sunspot region loops connect.
6. A dwarf planet orbits the Sun, has spherical gravity but didn't clear its orbit.
7. A sunspot is a dark, cooler gas area on the Sun's surface.
8. Luminosity is the actual brightness of a star at a standard distance from Earth.
9. A light - year is the distance light travels in one year.
10. Apparent magnitude is a star's brightness as seen from Earth.
11. In the geocentric model, Earth is at the center and Sun orbits it. The drawing should have Earth labeled at the center and Sun orbiting around it.
12. The solar system formed when dust, ice and other small objects were pulled together by gravity to form larger bodies like planets and the Sun.
13. The inner planets are closer to the Sun and are hotter than the outer planets, so the statement "The inner planets are cooler than the outer planets" is False.

Answer:

1. Rotation
2. Revolution
3. Planet
4. Astronomical unit
5. Solar flare
6. Dwarf planet
7. Sunspot
8. Luminosity
9. Light - year
10. Apparent magnitude
11. Draw Earth at the center with Sun orbiting it and label them.
12. Dust, ice and other small objects were pulled together by gravity to form the solar system.
13. False
