Y6 Geog Meanders and Oxbow lakes

Water moving faster has more energy to _______. This occurs on the outside of the bend and forms a river cliff.

• Erode

• Deposit

• Enhance

• Destroy

When erosion happens in a sideways direction

• Vertical

• Lateral

• Abrasion

• Solution

New deposition seals off the ends and the cut-off becomes an ________________ that will eventually dry up.

• Oxbow Lake

• Kidney scar

• Flood Plain

• Meander

The lateral erosion on the outside bend causes undercutting of the bank to form a __________.

• River Cliff

• River Slope

• River Bank

• River Erosion

Water twists and turns around stones and other _______________ resulting in areas of slower and faster water movement.

• Obstructions

• Rapids

• Waterfalls

• Meanders

Often during a _________ the river will cut through the neck.

• Tide

• Flood

• Storm

• A period of low velocity

Erosion _____________ the neck of the land within the meander and as the process continues, the meanders move closer together.

• Narrows

• Widens

• Grows

• Builds up

Water on the inner bend is slower, causing the water to slow down and ________________ material

• Erode

• Deposit

• make

• destroy

As the river makes its way to the ____________________, it gains more water and therefore more energy.

• Upper course

• Middle course

• High course

• Lighter course

Due to erosion on the outside of a bend and _____________ on the inside, the shape of a meander will change over a period of time.

• Deposition

• Erosion

• Solution
