GED Social Studies TestGeography and the WorldMedium
A geographer is analyzing a region where a large river flows into an ocean or sea, depositing a significant amount of sediment and forming a distinctive landform with multiple distributaries. What geological feature is the geographer observing?
- AFjord
- BPeninsula
- CDelta
- DEstuary
Show answer & explanationAnswer & explanation
Correct answer: C. Delta
A delta is a landform that is formed at the mouth of a river, where its current slows down upon entering a larger body of water, leading to the deposition of sediment and the formation of branching distributaries.
Why the other options are wrong
- A. A fjord is a long, narrow, deep inlet of the sea between high, steep-sided cliffs, typically formed by glacial erosion.
- B. A peninsula is a piece of land almost surrounded by water but connected to the mainland on one side.
- D. An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it.
River Delta
A river delta is a landform that forms from the deposition of sediment carried by a river as its flow leaves its mouth and enters slower-moving or stagnant water.
- Formed at the mouth of a river.
- Characterized by multiple distributaries (channels).
- Often very fertile and densely populated.
Memory trick: Coastal shapes show where 'land' meets 'sea' in unique ways.
