What is the name for an area of land which is covered in water when a river bursts its banks.
Floodplain
When the river flows over flatter land they develop large bends called ..........
Meanders
Floodplains form due to both erosion and what other process?
Deposition
The build-up of deposited sediment on the inside bank of a river is known as a ________________ (or sometimes river beach).
Slip off slope
The lateral erosion on the outside bend causes undercutting of the bank to form a ___________
River cliff
Deposition can occur to cut off a meander, leaving a horseshoe-shaped ___________.
Oxbow lake
This is the sheer power of the water as it smashes against the river banks. Air becomes trapped in the cracks of the river bank and bed, and causes the rock to break apart. What type of erosion is this?
Hydraulic action
When pebbles grind along the river bank and bed in a sand-papering effect. What type of erosion is this?
Abrasion
When rocks that the river is carrying knock against each other. They break apart to become smaller and more rounded. What type of erosion is this?
Attrition
When the water dissolves certain types of rocks, eg limestone. What type of erosion is this?
Solution
When the river loses energy, it drops any of the material it has been carrying. This is known as __________.
Deposition
This is where a river begins
Source
This is the point at which two rivers meet
Confluence
where a river meets the sea
Mouth
a small river or stream that joins a larger river
Tributary
As a river goes around a bend, most of the water is pushed towards the outside. This causes increased speed and therefore increased ___________.
Erosion
