Multiple Choice

What are comets primarily made of, and why are they sometimes called "dirty snowballs"?

• a) Metal and rock, because they are found in the asteroid belt
  

• b) Ice, dust, and rock, because they contain frozen gases and dust
  

• c) Molten lava, because they originate from volcanoes on other planets
  

• D) Gas and Plasma, because they burn up in Earth's atmosphere

• A comet's tail always points away from the Sun due to solar wind and radiation pressure.
• Comets do not have tails when they are far from the Sun.
• The tail is formed by ice melting from the comet's surface.
• A comet's tail points towards the Sun due to gravity.
