Erosion and deposition

This photo represents...

• A river overflowing its banks

• A river in flood breaking the delta

• A flooding river breaking a levee

• The upper course of a river in flood

The photo represents a ...

• Valley

• Mountain range

• Canyon

• Gorge

• River course

The image was created MAINLY by...

• A river flowing downhill and eroding the rock

• A tectonic uplift

• Harder rock eroding faster than softer rock

• Tectonic plates colliding

The water in the front of the photo is green because...

• An ox-bow lake has formed

• The banks of the river are cut unevenly

• The water is stagnant as it is not attached to the river

• It is still part of the river

This river is a good example of...

• An ox-bow lake

• Meandering

• levees being formed

• A delta being formed

The white part in the river represents...

• deposition due to slow water movement

• deposition due to fast water movement

• erosion due to slow water movement

• erosion due to fast water movement

This photo represents....

• A levee

• Tributaries joining main river

• a delta

• Meandering

What is NOT a reason why this feature was formed?

• silt blocking the main river path

• the river flows faster than the sea

• deposition

• the river slows down when it reaches the mouth

What is the best statement for the upper course of a river?

• Fast flowing, lots of deposition, gentle sides (the slope)

• Slow flowing, little deposition, steep sides

• Fast flowing, little deposition, steep sides

• Slow flowing, lots of deposition, gentle sides

What is the best statement for the lower course of a river?

• Fast flowing, lots of deposition, gentle sides (the slope)

• Slow flowing, little deposition, steep sides

• Fast flowing, little deposition, steep sides

• Slow flowing, lots of deposition, gentle sides
