Cuspates and Tombolo Formation Guide

Understanding Coastal Landforms Year 7 Geography UK National Curriculum

What Are Coastal Landforms?

Shaped by waves, wind and currents Created by erosion and deposition Change over thousands of years Found where land meets the sea

Wave Refraction Process

What is a Cuspate Foreland?

Triangular-shaped coastal feature Made from deposited sediment Points out to sea like an arrow Formed by waves from two directions

Quick Check: Cuspate Features

Which shape best describes a cuspate foreland? A) Circular B) Triangular C) Rectangular D) Straight line

Formation of Cuspate Forelands

Waves approach from two angles Sediment carried by longshore drift Material deposited where currents meet Builds up over hundreds of years

What is a Tombolo?

Ridge of sand or shingle Connects mainland to an island Acts like a natural bridge Can be permanent or temporary

Cuspate vs Tombolo Comparison

{"left":"Points out to sea\nTriangular shape\nWaves from two directions\nNo island connection","right":"Connects to island\nRidge or bar shape\nWaves bend around island\nCreates land bridge"}

Drawing Task: Label the Diagram

Draw and label a tombolo formation Include: mainland, island, connecting ridge Add arrows showing wave direction Mark areas of deposition

Worksheet Success Tips

Read questions carefully Use geographical vocabulary Draw clear, labeled diagrams Explain formation processes step by step
