Three types of weathering
Mechanical, chemical and biological weathering.
1 of 17
Mechanical weathering
Physical actions of rain, frost and wind that create weaknesses in rocks.
2 of 17
Chemical weathering
Minerals reacting and breaking down-for example oxidation.
3 of 17
Biological weathering
Rocks/land broken down by living organisms-plants or animals.
4 of 17
Two types of mass movement
Sliding and slumping.
5 of 17
Sliding
A section of land falls down a slope and dislodges other material on it's way down.
6 of 17
Slumping
Material at the bottom of the slope moves outward.
7 of 17
Four types of erosion
Abrasion, hydraulic action, attrition and solution.
8 of 17
Abrasion
Sediment thrown by the water, rubbing away the material.
9 of 17
Hydraulic action
The power and pressure of the water causes weaknesses in the rock.
10 of 17
Attrition
Pebbles hit each other or landforms, making rocks break and get smaller and rounder.
11 of 17
Solution
Sediment is dissolved in the water.
12 of 17
Four types of transportation
Traction, saltation, suspension and solution.
13 of 17
Traction
The movement of large sediment rolled along in the water.
14 of 17
Saltation
Small pieces of sediment picked up temporarily by the water.
15 of 17
Suspension
Small sediment suspended in the water.
16 of 17
Solution
When minerals dissolve in the water.
