Weathering : 

Weathering Weathering is the breakdown of rock “in situ” (where it is) Erosion involves taking away and further breaking down rock as it moves. There are four main agents of erosion Rivers (fluvial), Sea (waves), Glaciers, Wind Task: Use this presentation as a base to add your own text and diagrams when asked for.

Mechanical weathering : 

Mechanical weathering is the breakdown of rock into smaller particles due to factors such as freezing and thawing release of pressure water absorption salt crystal formation landmass uplift plant root growth actions of animals And abrasion 18

Biological : 

Biological Biological weathering is caused by activities of living organisms - for example, the growth of roots or the burrowing of animals. Tree roots are probably the most occurring, but can often be by animals.Its where animals or roots breaks the rock apart.

Chemical weathering : 

Chemical weathering is the dissolution, carbonation, or oxidation of rock and mineral by chemical means only, mostly from reactions with water or the acids contained in rainwater. Other materials are formed in the process.

Climate and Weathering : 

Climate and Weathering Research the average annual temperature and precipitation of Barbados. Note what it is here and describe what type of weathering occurs here.

Next : 

Next We will be looking at the limestone landscape of Barbados and comparing it to other limestone landscapes worldwide. What is the role of limestone in shaping some of the features we have Caves, underground streams, gulleys, Humans and the limestone environment
