River Processes
- Erosion
- Abrasion
- Sandpaper Action
- Rock scrape
against the
channel, wearing it
away.
- Most erosion
occurs this way
- Rock scrape
against the
channel, wearing it
away.
- Sandpaper Action
- Attrition
- Eroded materials
smash against each
other, breaking
pieces off.
- Edges get rounded off.
- Edges get rounded off.
- Eroded materials
smash against each
other, breaking
pieces off.
- Solution
- River water dissolves
some rock, such as chalk
and limestone
- River water dissolves
some rock, such as chalk
and limestone
- Hydraulic Action
- The force of the water
breaks particle of rocks off
the river channel
- The force of the water
breaks particle of rocks off
the river channel
- Abrasion
- Deposition
- Occurs when the river loses velocity.
- Volume of water falls.
- Amount of eroded materials
increases.
- When water is shallower
- When the river
reaches the mouth.
- Volume of water falls.
- Occurs when the river loses velocity.
- Transportation
- Solution
- Soluble materials are carried along
when they are dissolved by the
water
- Soluble materials are carried along
when they are dissolved by the
water
- Suspension
- small, undissolved particles are carried
along on the water. This makes the water
look dirty
- small, undissolved particles are carried
along on the water. This makes the water
look dirty
- Traction
- This is when large rocks are rolled by the force of
the water. they are too large to be carried or
dissolved.
- This is when large rocks are rolled by the force of
the water. they are too large to be carried or
dissolved.
- Saltation.
- When relatively large particles of rock are
bounced along the botom of the river. these are
too large to be dissolved or suspended
- When relatively large particles of rock are
bounced along the botom of the river. these are
too large to be dissolved or suspended
- Solution
- There are three main processes that take
place in a river, These are they.
