what is water ?
water is particles that's keep us hydrated and is essential to all life on earth
1 of 31
what is precipitation
rain, hail,sleet,snow that falls from the clouds
2 of 31
what is condensation
when water vapour cools and turns into clouds
3 of 31
what's is evaporation
when the sun heats up water from the sea and it goes into the air
4 of 31
what is transpiration
when the sun heats up water from the leaves of trees
5 of 31
what's are three ways on how the rainfall reaches the river
surface run off
through flow
ground water flow
6 of 31
what work does rivers do ?
1.rivers erode the banks
2.rivers carry away material
3.rivers drop material
7 of 31
what are the three ways rivers do their work?
8 of 31
what is abrasion
rocks carried along the river wear down the river bed and banks
9 of 31
what is attrition
rocks being carried by the river smash together and break into smaller, smoother round particles
10 of 31
what's hydraulic action
the force of the river against the banks causes air to be trapped in cracks, the pressure weakens the banks and gradually wears it away
11 of 31
soluble particles are dissolved into the river
12 of 31
what do geographers call the material a river carries
a load
13 of 31
what does solution mean
minerals are dissolved in the water and carried along in solution
14 of 31
what does suspension mean
light material is carried along in the water
15 of 31
what is saltation
small pebbles are bounced along the river bed in a leap frog movement
16 of 31
what is traction
large boulders and rocks are rolled along the river bed
17 of 31
what is deposition
what a river loses energy it will drop some of the materials is was carring
18 of 31
when does deposition occur
1.when a river enters an area of shallow water
2.when the volume of water decreases
3.towards the end of a rivers journey
19 of 31
what are the tree stages of a river
1. upper course
2.middle course
3.lower course
20 of 31
name three ways a river changes...
1.narrow river channel
2.river gets wider and deeper
3.much wider as it enters the sea
21 of 31
what is a waterfall
a waterfall is a geological formation where flowing water rapidly drops in height as it flows over a steep area or a cliff
22 of 31
what part of the river are waterfalls found in
upper course
23 of 31
what is a meander and where are they found ?
a meander is a bend in the river and are usually found in the middle course of the river
24 of 31
what is flooding
flooding occurs when a river gets more water in it, than its channel can hold then the river bursts its banks into the floodplain.
25 of 31
physical causes of flooding:
1.soild and rock type
2.vegetation type and coverage
3.precipitation, amount and duration
4.the relief of the land
26 of 31
human causes of flooding:
3.increased population
27 of 31
what is a positive and negative impact to flooding ?
positive: flooding deposits a fine slit onto the floodplain making it very fertile and perfect for farming
negative:flooding can cause devastating damage to homes and possessions.
28 of 31
what is flood management ?
flood management schemes aim to control flooding and reduce the risk of flooding
29 of 31
what is hard engineering
these are artificial and man made features that are added to the river
30 of 31
what is soft engineering
these tend to work with the river in a more natural way
