Effects of a tropical cylone on the land:
Flooding- caused by heavy rainfall and storm surge. Impacts most greatly felt in low land and coastal areas.
Landslides- large downward movement of soil and rock may occur where heavy rainfall occurs in steep areas.
Vegetation- native vegetation is often destroyed by strong winds, trees can be blown over.
Impacts on soils- thick deposits of silt are deposited on lowland areas by floods.
Storm surges deposit a layer of salt, causing salinisation of coastal soils.
Coastal erosion- heavy seas and storm surge cause coastal erosion and may alter the shape of beaches.
