1 Features of EROSION & Features of DEPOSITION
RIVERS Features of EROSION & Features of DEPOSITION

2 RIVER EROSION

3 Is a feature of erosion by a young river
A waterfall A Waterfall is a feature of River EROSION because a river running downhill cuts its passage through rock and earth where it can and when it meets a sudden drop in land a waterfall is formed. Is a feature of erosion by a young river

4 River erodes the outside of the meander and deposits on the inside.
A Meander in a river

5 On the inside of the meander, Deposition happens
The river speeds around the outside of the bend as it cuts its way; the water is much slower on the inside of the bend where mud and silt etc are dropped or deposited. On the inside of the meander, Deposition happens

6 OX-BOW LAKE

7 Ox bow lake is a feature of river deposition

10 Material that is transported by the waves along a coastline is eventually deposited forming distinctive deposition features. The sea Coastal Deposition Landforms: Features and Formation

11 These are two main deposition features that you need to learn the formation of. These are: 1. Beaches 2. Spits Sea deposition Beaches and spits

12 Features of coastal deposition
Beaches Beaches are the main feature of deposition found at the coast, these consist of all the material (sand, shingle etc.) that has built up between the high and low tide mark. Features of coastal deposition The main feature of coastal deposition is the BEACH

13 Longshore drift moves material along the coastline.
A spit forms when the material is deposited (or left behind / dropped). Over time, the spit grows and develops a hook if wind direction changes further out. Waves cannot get past a spit, which creates a sheltered area where silt is deposited and mud flats or salt marshes form. Spits Spits are long narrow ridges of sand and shingle which project (stick out) from the coastline into the sea.

14 This spit is approximately 20 miles long
Farewell Spit , On New Zealand’s South Island This spit is approximately 20 miles long

18 Headlands and bays Headland Bay The headland is the part that remains pointing or jutting out into the sea The bay is the curved or scooped out space that the sea waves eroded away

19 How Headlands and Bays form

20 Caves, arches, stacks and stumps

21 Sea Erosion These are STACKS and STUMPS
