A cold period of time during which the Earth's glaciers expanded widely.
1 of 37
A moving body of ice.
2 of 37
Processes involving rivers.
3 of 37
Large surfaces of rock underneath the Earth's surfaces.
4 of 37
Uses radioactive testing to find the age of rocks.
5 of 37
Type of rock.
6 of 37
Growing a forest of trees (opposite of deforestation).
7 of 37
Where the land meets the sea
8 of 37
A coastline made up of both hard and soft rock running PARALLEL to the coastline meaning the rock erodes at different rate.
9 of 37
A coastline made up of both hard and soft rock running PERPENDICULAR to the coastline
10 of 37
When water is forced into cracks in the rock in cliffs, compressing the air thus forcing the rock apart.
11 of 37
When loose rock (sediment) is thrown against the cliff, chipping parts off.
12 of 37
Loose sediment is swirled by the waves, smashing against other rocks. Eventually the sediment becomes smaller, smoother and more round.
13 of 37
Acid in the waves erodes the chemical compounds creating a solution, so the rock has been dissolved.
14 of 37
How long and far the wind has been blowing over the sea, and how straight it is.
15 of 37
Add sediment to a beach, low power and weak backwash.
16 of 37
Take away sediment from a beach, high power and a strong backwash.
17 of 37
Longshore Drift (LSD)
Process of deposition and transportation by waves on a beach.
18 of 37
Structures built by people.
19 of 37
Where the natural environment is used to help reduce coastal erosion and river flooding.
20 of 37
Small rivers leading to a big river.
21 of 37
Start of the river.
22 of 37
The area which is drained by a river and its tributaries.
23 of 37
Where the river ends. This is out on the coast. The river is slow and wide at this point.
24 of 37
A stream or river that flows into a mainstream river, which does not flow into a sea.
25 of 37
The meeting of two or more bodies of water, usually refers to the point where a tributary meets the main river body.
26 of 37
This line seperates drainage basins. It runs along a geographical barrier such as a ridge, hill or mountain.
27 of 37
Bend in a river.
28 of 37
The total length of all the steams in the basin, divided by the total basin area.
29 of 37
A way of identifying/showing how a river changes during its course.
30 of 37
All deposits from a river.
31 of 37
Easiest course for a river to take.
32 of 37
Maximum discharge (cumecs)
33 of 37
The time taken between peak rainfall and peak discharge.
34 of 37
Shows the increase in discharge on a hydrograph.
35 of 37
Shows the return of dishcarge to normal/base flow on a hydroraph.
36 of 37
A systematic process of evaluating the potential risks that may be involved in an activity.
