| Breakdown of rocks into segments | Weathering |
| Two types of weathering include: | Physical (mechanical) and Chemical |
| Physical or mechanical weathering makes smaller bits of | the same stuff |
| Types of physical (mechanical) weathering include: | exfoliation, frost wedging, root pry, sand abrasion |
| The mechanical disintegration, splitting or break-up of rock by the pressure of water freezing in cracks | frost wedging (frost action) |
| Plants and plant roots also tend to pull rock apart | example of Root Pry |
| Chemical weathering | breakdown of rock through chemical reactions/changing chemical composition of rock |
| Types of chemical weathering include: | carbonation, hydrolysis, oxidation, acid rain |
| ________is the mixing of water with carbon dioxide to make carbonic acid. This type of weathering is important in the formation of caves. | Carbonation |
| Rate of weathering depends on what three things? | climate, rock type and surface area |
