Chapter 1 - Oceans and Rivers
New Vocabulary - Oceans
Ocean
:
A large body of SALT water
Coast (coastline)
:
The land next to the ocean. Where the ocean and the
land meet.
Erosion
:
The act of water wearing away the land. How water can change the
land. Breaks down soil and rocks and carries them away.
How do oceans change land? (2 ways on pages 5-6)
1. Take away land Big waves wash away land and rocks. Break up large rocks into smaller and
smaller pieces.
Washes away cliffs.
2. Add to the land Waves can also bring sand back to a beach.
Adds finer and finer sand to the beaches
Where does sand come from? Page 7
The waves break down the rocks and shells into smaller and
smaller pieces. The waves wash the sand back onto the beach. This
can take 1,000s of year.
What are the two types of beaches and how are they
formed? Page 7
Sandy beaches:
rocks and shells have been pounded up
into smaller pieces by the water.
Rocky beaches: less pounding of the rocks by the waves.

New Vocabulary – Rivers (pg. 18)
River
:
A stream of fresh water moving across the land.
Lake
:
A pool or body of fresh water that is surrounded by land.
Flood
:
Too much water that overflows from a river, lake or stream
and covers the land.
Flood Plain
:
The land that usually gets covered by water during a flood.
Usually flat and has very rich soil.
What are some differences between rivers and oceans?
(Page 18)
Oceans have salt water – rivers have fresh water
Oceans are much bigger than a river.
Rivers flow across the land – Ocean waves smack into the
land at the coast.
Rivers are a stream - oceans are LARGE bodies that
cover most of the earth.
There is more water in the oceans than in the rivers.
How or where do rivers start and end (4 ways – page 19)
1. Rivers can flow into other rivers
2. Some rivers start underground. Some end underground.
3.
Some rivers start in lakes. Some rivers can end in lakes
4.
Rivers flow into oceans
Explain why a river runs slowly or quickly. (Page 19)
If the land is flat, a river runs slow. If the land is steep
and down hill, the river runs fast.
Deeper rivers can run more slowly.
Heavy rains can cause a river to run faster.
How do rivers change land? (2 ways on pages 22-23)
1 – Take away land –
Floods can erode the land and carry away rocks and soil.
Rivers wash away the land from the edge of the river.
2 – Give back land –
Floods leave behind soil when the flood is over.
Rivers carry soil from one place to another.
How can a flood be good for the earth? (Page 23)
Floods leave behind rich soil that is good for farming.
