COASTAL DEPOSITION PROCESSES

1. I can explain how the sea shapes the landscape by the processes of: 1. Longshore Drift

Explain the formation of a sand spit. You may use a diagram(s) in your answer. 4

Landscape types Within the context of two landscape types, selected from either:&nbsp; Glaciated uplands and Coastal landscapes OR Upland limestone and Rivers and their valleys&nbsp; The identification and formation of the following landscape features:&nbsp; 1. COASTAL LANDSCAPES The formation of the following landscape features: 1. Headlands and Bays 2. Cliffs 3. Cave and Arches 4. Stacks 5. Spits and Sand bars

Match these grid references with the correct coastal features. Choose from features: cliff; stack; sand spit; arch.

1. Description: A free-standing piece of rock called a stack which is separate from the headland. 2. Formation: Waves attack a line of weakness in the headland, developing into a cave and the arch, continuous erosion will cause the roof of the arch to collapse. 3. Process: By hydraulic action the force of the waves crashing against the shore and cliffs.&nbsp; 4. Process: And by abrasion when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.

Coastal Processes of Deposition

Longshore Drift When the wind approaches the beach at an angle the waves (swash) transport sand up the beach at that angle. Gravity pulls waves (backwash) down the beach at 90° Over time the many waves cause sand particles to move along the beach.&nbsp;

3. I can explain the formation of the following features:

1. Headland &amp; Bays 2. Cliffs 3. Caves &amp; Arches 4. Stacks 5. Spits &amp; Bars

Look at Diagram Explain the formation of a stack. You may use a diagram(s) in your answer. 4

1. Description: Cliffs form when there is harder, resistant rock. 2. Formation: The power of the wave is greatest where it hits the base of the cliff. 3. Process: By hydraulic action the force of the waves crashing against the shore and cliffs.&nbsp; 4. Process: And by abrasion when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.

1.Formation: Waves attack a line of weakness in the headland to form a cave. 2. Formation: When erosion breaks though the headland an arch is formed 3. Process: By hydraulic action the force of the waves crashing against the shore and cliffs.&nbsp; 4. Process: And by abrasion when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.

1. Description: Sand spits are long narrow ridges of sand that jut out into the sea. 2. Formation: Form where the coastline changes direction. 3. Process: Longshore Drift, when the wind approaches the beach at an angle the waves transport sand up the beach at that angle (swash). 4. Process: Gravity pulls waves (backwash) down the beach at 90°

Choose from features: cliff; headland; bay; stack. Explain the formation of one of the coastal features listed above. You may use a diagram(s) in your answer.

Coastal Processes of Erosion

Hydraulic Action This is the force of the waves crashing against the shore and cliffs.&nbsp; Abrasion This is when rocks carried by the waves are thrown against the cliffs, wearing away the coastline. Attrition Rocks carried by the waves smash into each other, wearing each other away and creating smaller material to be used as erosion. Solution Chemicals in our sea water dissolve minerals in certain rocks.

Match these grid references with the correct coastal features Choose from features: cliff; headland; bay; stack.

1. Description: Sand bars are long narrow ridges of sand when the spit reaches the other&nbsp;side of the bay to join land again. 2. Formation: Form where the coastline changes direction. 3. Process: Longshore Drift, when the wind approaches the beach at an angle the waves transport sand up the beach at that angle (swash). 4. Process: Gravity pulls waves (backwash) down the beach at 90°

COASTAL LANDSCAPES National 5 Geography

1. Description: When there are alternate bands of hard and soft rock in contact with the sea. 2. Formation: The sea erodes the soft rock more quickly forming a Bay; and leaving the hard rock jutting out as a Headland. 3. Process: By hydraulic action the force of the waves crashing against the shore and cliffs.&nbsp; 4. Process: And by abrasion when rocks carried by the waves are thrown against the cliffs, wearing away the coastline.
