1. Question 1

   What is meant by a meteoroid?

   • Aa small object in space that orbits the Sun
   • Ban object that enters Earth's atmosphere and burns up
   • Can object that falls to Earth's surface
   • Da fast-moving star

   Answer: A. a small object in space that orbits the Sun

   A meteoroid is a fragment of rock or metal that moves in space and orbits the Sun. The other options refer to a meteor (second option), a meteorite (third option), and a misconception about stars.

3. Question 3

   Which of the following are characteristics of asteroids?

   • Acomposed of ice and dust
   • Busually found in the asteroid belt between Mars and Jupiter

5. Question 5

   What causes a meteoroid to burn up in the atmosphere?

   • Afriction with air
   • BEarth's gravity
   • Csolar radiation
   • Dmagnetic field

   Answer: A. friction with air

   Friction between the meteoroid and air molecules generates high heat, causing the meteoroid to burn up.
