Difficulty: EasyOceans, Coastal Processes, and Coastal Landforms

Coastal processes shape coastal environments through marine erosion, transportation, and deposition. Which of the following features is created primarily by coastal deposition?

  1. A
    Oxbow lake
  2. BeachAnswer
  3. C
    Scree slope
  4. D
    Marble ridge

Answer

Beach
Beaches are temporary or permanent accumulations of sediment (sand, gravel, or pebbles) deposited along the coast by constructive waves where wave energy is low.

Step-by-Step Solution

1
Identify the primary agent of coastal deposition
Constructive waves build up landforms by depositing sediments like sand and pebbles along the shoreline.
Coastal landforms are classified into erosional features (like sea cliffs, arches, stacks) and depositional features (like beaches, spits, bars).
2
Evaluate the landform options against coastal deposition
Beaches consist of accumulated sand and shingle deposited by swash-dominated wave action.
Distinguish coastal marine landforms from river landforms, slope weathering features, and rock metamorphic structures.
