Presentation Transcript

  1. What is a solar system? A solar system is the sun and all objects that orbit the sun under its gravitational influences.

  2. What makes up a solar system? The solar system is made up of planets, asteroids, moons, comets and meteoroids.

  3. What is a planet and can you name them? A planet is a satellite of the sun; a satellite is any object that orbits or revolves around another object.

  4. What is an asteroid? An asteroid is a solid rocky and/or metallic body that independently orbits the sun.

  5. What is a moon? A moon is a body that orbits a planet or an asteroid as those objects orbit the sun.

  6. What is a comet? A comet is mainly composed of solids that easily change to gases when heated, which may form a tail.

  7. What is a meteoroid? • A meteoroid is a very small fragment that orbits the sun • A meteor is a meteoroid that passes through the Earth’s atmosphere • If the meteor survives the trip and lands on Earth’s surface is called a meteorite

  8. How does earth show evidence for impact events? • An impact event is when comets, asteroids and meteoroids are forced by gravity to collide with planets. • These impact events are seen on the surface of the planet in the form of craters or impact craters • Craters have been linked to global changes in climate as well as extinctions (End of the Dinosaurs – Yucatan Peninsula)
