To what extent do you agree that river landforms can be classified as either erosional or depositional? Many different landforms are made by either deposition or erosion and there are some cases where they can be classified as both. Erosional landforms are caused by erosion which is the breaking down and transportation of particles from one area to another. Depositional landforms are made when particles are deposited somewhere else. In my opinion I think that river landforms can be classified

magnificent headlands and various other wonderful features‚ being well over 15000 years old this region showcases some magnificent attractions. These regions however are now faced with issues regarding enviromental degradation and habitat endangerment. There are many issues however some of the more significant problems are erosion‚ longshore drift and high rise development. There are three key factors in the geographical processes that affect the coastal enviroments. There are erosion‚ deposition

coast at Hengistbury Head? Setting the scene Hengistbury Head is a scenic and historic headland near the town of Bournemouth on the south coast of England. It stands mid-way between Poole harbour and Hurst spit and forms the main division between Poole and Christchurch Bays. Coastal Processes | Description | Sub Aerial | Coastal erosional processes that are not linked to the action of the sea. Erosion occurs via rain‚ weathering by wind and frost. Its impact is often seen in soil creep‚ slumping

Section A - Restless Earth The earth’s structure At the centre of the earth is the core. Surrounding that is a mass of molten rock called the mantle. The thin layer on the outside is called the crust. There are two types of crust‚ continental and oceanic. The crust is made up of seven major plates and many smaller ones. The plates move due to convection currents rising in the mantle. Distribution of earthquakes and volcanoes Mainly found along plate boundaries. In
