1. Moving water is the major agent of the erosion that
has shaped Earth's land surface.
A. Because of gravity, water moves downhill
2. Amount of Runoff
A. Depends on 5 factors
1. amount of rain
2. vegetation (plants)
3. type of soil
4. shape of land
5. how people use the land
3. Through erosion a river creates:
A. valleys, waterfalls, flood plains,
meanders, and oxbow lakes
4. Deposition creates landforms such as:
A. alluvial fans and deltas
5. Exploring a river - pg. 236 - 237
6. Groundwater
A. not all water evaporates, some soaks into the
ground

8 - 3 Force of Moving water
Right side
Vocabulary -
energy
abrasion
load
friction
1. 2 kinds of energy
1. kinetic - energy due to motion
2. potential - stored energy
2. Gravity pulls water down a slope and
changes the potential energy to kinetic energy.
3. How does sediment enter the water?
A. washes
or falls into a river as a result of:
1. mass movement
2. runoff
B. erodes
from the bottom or sides of the river
4. What affects how fast the river flows
and how much sediment it can erode?
A. rivers slope
B. volume of flow
C. shape of its
stream bed
5. Fast flowing rivers-
A. carry
more and larger particles of sediment
6. Slow flowing rivers -
A. sediment
load is deposited
B. heaviest
falls out first

8-5 and 8-6 Waves and Wind
Right Side
Vocabulary
beach-
deflation-
1. Energy in waves comes from the wind that blow's across
the surface
2. Waves
A. energy causes the water to move up and down as
the wave goes by
B. erosion along coasts are caused by waves
