  • What type of tide occurs when the tidal range is at its greatest?
    extreme high tide
  • True or false: Mass of Hariz Adam on the Earth is the same on the Moon.
    True
  • Most massive object in our solar system?
    Sun
  • cloud of dust and gas
    nebula
  • state the energy changes in the diagram
  • How does the sun's mass effect the solar system?
    The sun has enough mass that its gravitational pull holds the planets and other objects in the solar system in orbit.
  • What is defined as, "the energy of motion?"
    Kinetic Energy
  • What is the amount of matter in an object? mass or weight?
    mass
