• 3 Types Currents, Waves, and Tides
• Currents Like rivers flowing through the Ocean
• Waves- swells or ridges caused by winds
• Tides- Regular rises and falls of the ocean
  created by the gravitational pull of the moon or
  the sun.
• All of these three moving waters vary in size

Landforms

• Landforms are formed by erosion
• Different kinds of erosion
• Water Erosion- Water picks up loose material and
  carries the material downstream slowly chipping
  away the contents of a river or stream
• Wind Erosion- wind picks up loose material and
  blows the material against rock surfaces, etc.
• Glacial Erosion- mass of ice that carves its way
  through a given area, pulled by gravity
