deposition

Question 1

flood plains

Answer 1

wide valley floor on either side of a river that occassionally floods
when floods occur rivers slow down, deposits material, this builds up a flood plain

Question 2

meanders also migrate….

Answer 2

downstream

Question 3

deposition that happens on the slip off slopes of meanders…

Answer 3

also build up flood plains

Question 4

levees are

Answer 4

natural embankments along the edge of a river channel
during floods eroded material is deposited over the whole flood plain
the heaviest material is deposited closest to the river channel because it drops first when the river slows down and loses energy
over time this deposited material builds up creating levees along the edges of a channel

Question 5

learn how to draw the diagram for levees

Question 6

estuaries and tidal areas

Answer 6

estuaries are found at the river mouth, land is close to sea level and valley is wide. the water here is tidal. when the water floods over the banks of the river it carries silt and sand onto the valley floor. as the tide reached its highest point the water has little energy so deposits. over time more mud builds up creating mudflats. at low tide the wide muddy banks are exposed.
