Marine erosion processes – Edexcel IAL Geography

A fully editable, ready-to-teach lesson on Marine erosion processes for Edexcel International A Level (IAL) Geography, Unit 2: Geographical Investigations – Crowded Coasts.

Lesson aim: To explain the processes of marine erosion and the factors that affect erosion rates.

Learning outcomes

• To explain hydraulic action, abrasion, attrition and solution
• To explain why erosion is concentrated in storms and at high tide
• To evaluate the factors that affect rates of erosion

Specification: 2.3.2 Landscapes and landforms — marine erosion processes (hydraulic action, abrasion, attrition)

What’s included

• Editable PowerPoint lesson (10 slides)
• Word worksheet: Processes of erosion
• Teacher notes and suggested answers in the speaker notes

Lesson overview

• Starter: A large storm wave can exert a pressure of over 25 tonnes per square metre on a cliff or sea wall.
• Four processes of marine erosion
• Which erosion process does most damage to cliffs? Does it depend on the rock?
• What controls the rate of erosion?
• Short-term and long-term erosion
• Why does a narrow beach make a cliff more vulnerable?
• Erosion processes
• Exam practice: Explain two processes of marine erosion. (4)
