1 OceansLakes Rivers Ponds Streams

2  The Earth produces resources that meet our needs such as soil, wood, and minerals.  Water is another important resource found in Earth’s oceans, lakes, rivers, ponds, and streams. There is much more water on the Earth than there is land!

3  Even though the ocean holds a lot of water, we cannot drink it because it is too salty!  When you go to the beach, you are probably swimming in salty ocean water.

Plants often grow along the pond edge.  Ponds are home to animals and insects such as bullfrogs, snapping turtles, dragonflies, mosquitoes, ducks and snakes.

21  A stream is a small flow of water, much like a small river. They are usually fresh water.  Streams have an important job. They drain the landscape, and move water and minerals towards the Earth’s oceans.  As water drains it generally begins in small creeks, which flow into larger and larger streams, and eventually into powerful flowing rivers.
