Earth's Water

  • We need water everyday
  • Living things on earth need water
  • plants use water to make their own food
  • humans and animals need to drink fresh water
  • fresh water is not salty
  • fresh water is found in lakes, ponds, rivers, and streams
  • ice and snow melt into fresh water

  • ocean is a large deep body of salt water
  • ocean covers 3/4 of the earth

  • ships carry people and things around the world

  • many living things in the ocean need salt water to stay alive
