This document discusses bodies of water and landforms. It describes how the ocean circulates through currents, waves and tides, which helps distribute heat. It also explains the hydrologic cycle of water between the atmosphere, oceans and earth. Additionally, it discusses different types of freshwater bodies like lakes, rivers and streams, as well as groundwater held in rock pores and drainage basins. Finally, it defines landforms and describes oceanic landforms such as continental shelves, sea floors and islands.

Landforms

2. I. Bodies of Water
A.Ocean Motion
1. The ocean circulates through currents, waves,
tides.
2. Currents act like rivers flowing through the ocean.
3. Waves are swells or ridges produced by winds.
4. Tides are the regular rising and falling of the
ocean
a. created by gravitational pull of the moon or
sun.
5. Motion of ocean helps distribute heat on the
planet.
a. winds are heated and cooled by ocean water.

3. B. Hydrologic Cycle
1. Hydrologic Cycle—cycle of water between
atmosphere, oceans, earth
C. Lakes, Rivers, and Streams
1. Lakes hold more than 95% of the earth’s fresh
water.
2. Freshwater lakes, like the Great Lakes, are result of
glacial action.
3. Saltwater lakes form when outlet to sea is cut off:
a. streams and rivers carry salts into lake.
b. salts build up with nowhere to go.

4. 4. Rivers and streams carry water to and from
larger bodies of water.
5. Tributaries are smaller rivers, streams that
feed into larger ones.
6. Drainage basin—area drained by river and
its tributaries.
D. Ground Water
1. Ground water—water held in the pores of
rock.
2. Water table—level at which the rock is
saturated.

5. E.Landforms
1. Landforms are naturally formed features on
Earth’s surface
F.Oceanic Landforms
1. Continental shelf—sea floor from continent’s
edge to deep ocean.
2. Sea floor has ridges, valleys, canyons, plains,
mountain ranges.
3. Islands are formed by volcanoes, sand, or coral
deposits.
