22. Vocabulary Definitions
Meteor –a streak of light caused when a meteoroid or comet dust burns up in the Earth’s atmosphere before it reaches ground (shooting star)
Meteorite – a meteoroid that reaches the Earth’s surface without burning up completely 22

23. Vocabulary Definitions
Asteroid – a small, rocky body that revolves around the sun
Comet – a small body of ice and rock that gives off gas and dust in the form of a tail as it passes close to the sun
Supernova – the death of a large star by exploding.

EQ: What is common between the inner planets?
Inner Planets
Inner Planets called Rocky planets or terrestrial planets
Mercury
Smallest Planet and closest to the sun
Mercury moves very slowly
No Moons
Rotation-spin on its axis 59 days
Revolution- orbit around the
Sun - year is equal to 88 Earth
days 23

26. -Virtually the same size, mass and Density as Earth
2. Venus
-Virtually the same size, mass and Density as Earth
-Sun rises in the west and sets in the East because it rotates opposite to Earth
-One day on Venus is about as long as a year on Earth
-Hottest surface because the atmosphere is a thick cloud of CO2 (464° C).
-Rains sulfuric acid
-No oceans, Active volcanoes
-No Moons
-Typically the brightest object in the sky. 27

27. Just the right distance from the sun
Standard: 4 Astronomy
3. Earth
Just the right distance from the sun
Temperatures are right to not completely freeze or boil away the water 28

28. Thin atmosphere and further from the sun so it is a cold planet
4. Mars
Last Inner planet
Thin atmosphere and further from the sun so it is a cold planet
Water is in solid form-ice
Largest volcanoes
2 moons
Rotation is 24 hours and 37 minutes – Similar to the Earth.
Revolution takes 1 year, 322 days 29
