2. Standard 1b. Students know the evidence from Earth and moon rocks indicates that the solar system was formed from a large nebular cloud of dust and gas about 4.6 billion years ago. Objective 1List and describe the 4 surface features of the moon. Objective 2Summarize the 3 stages by which the moon formed. Objective 3Compare and Contrast the moons of other planets. Objective 4Describe asteroids and comets. Objective 5Compare meteoroids, meteorites, and meteors AssessmentChapter Test ReviewDaily Bellwork, Science Starters

5. Any large body that orbits a planet is a SATELLITE. If it is a natural satellite, it is a MOON. Any large body that orbits a planet is a SATELLITE. If it is a natural satellite, it is a MOON.

6. Lighter areas are HIGHLANDS (mountains/volcanoes) Lighter areas are HIGHLANDS (mountains/volcanoes) Darker areas are MARIA (lava fields) Darker areas are MARIA (lava fields) The surface of the moon is covered in bowl-shaped depressions called CRATERS The surface of the moon is covered in bowl-shaped depressions called CRATERS – Most of the moon’s craters formed from ASTEROIDS colliding with the moon for 4 billion years – The moon is covered in craters because it has no atmosphere to protect it The moon is covered in dust and rock from space debris called REGOLITH The moon is covered in dust and rock from space debris called REGOLITH Lunar rocks are very similar to Earth’s rocks. They are Igneous. Lunar rocks are very similar to Earth’s rocks. They are Igneous.

8. Giant Impact Hypothesis Mars-sized object collided with Earth 4 billion years ago. Chunks ejected from earth and orbited the Earth, clumping together to form the moon. Lunar Interior The moon was originally covered in an ocean of molten rock. Over time it cooled and denser material sank to the center giving it layers. Meteorite Bombardment Asteroids and debris left over from the formation of the solar system continually struck the moon forming craters.

13. Fragments of rock that orbit the sun More than 50,000 Ceres = largest Asteroid Belt= Main area of most asteroid orbits between the inner and outer planets. Looks like a star with a tail Made of ice, rock, and cosmic dust Orbit the sun Tails form when sunlight melts the ice into gas Small bits of rock Less than 1mm When a meteoroid enters the atmosphere it burns up, creating a bright light or ‘shooting star’ or METEOR Meteorite= if a meteoroid does not burn up entirely and lands it is called a METEORITE
