MCQs on Sea cliffs, Sea caves, Beaches, Sandbars, and Lagoons – World Geography
Q1. What is the primary process responsible for the formation of sea cliffs?
a) Wind erosion
b) Glacial erosion
c) Wave erosion
d) River erosion
Show Answer
Correct Answer: c) Wave erosion
Explanation: Sea cliffs are formed by the constant action of waves eroding the coastline, creating steep, rocky features.
Q2. What is the main cause of sea cave formation?
a) Coastal winds
b) Seasonal winds
c) Sea waves
d) Rivers
Show Answer
Correct Answer: c) Sea waves
Explanation: Sea caves are formed by the constant action of sea waves on rocks, eroding and creating cave-like structures.
Q3. Which of the following is a characteristic of a sandy beach?
a) Steep slope
b) Rocky shore
c) Gentle slope
d) Vertical walls
Show Answer
Correct Answer: c) Gentle slope
Explanation: Sandy beaches typically have a gentle slope, allowing for the accumulation of sand and the formation of a beach.
Q4. What is a sandbar?
a) A submerged or partially exposed ridge of sand
b) A steep, rocky coastal feature
c) A cave formed by wave action
d) A shallow body of water separated from the sea by a barrier
Show Answer
Correct Answer: a) A submerged or partially exposed ridge of sand
Explanation: A sandbar is a submerged or partially exposed ridge of sand, often formed by the deposition of sediment by currents or waves.
Q5. What is a lagoon?
a) A submerged or partially exposed ridge of sand
b) A steep, rocky coastal feature
c) A cave formed by wave action
d) A shallow body of water separated from the sea by a barrier
Show Answer
Correct Answer: d) A shallow body of water separated from the sea by a barrier
Explanation: A lagoon is a shallow body of water, often separated from the sea by a barrier such as a sandbar, coral reef, or spit.
Q6. Which of the following is a common feature of a sea cave?
a) Vertical walls
b) Gentle slope
c) Rocky shore
d) Steep slope
Show Answer
Correct Answer: c) Rocky shore
Explanation: Sea caves are typically found along rocky shores, where wave action has eroded the rock to create cave-like structures.
Q7. What is the primary force responsible for the formation of sandbars?
a) Wind
b) Tides
c) Waves
d) Rivers
Show Answer
Correct Answer: c) Waves
Explanation: Sandbars are primarily formed by the action of waves, which deposit sediment in ridges along the shoreline or offshore.
Q8. Which of the following is a type of lagoon?
a) Atoll
b) Sea cave
c) Sea cliff
d) Sandbar
Show Answer
Correct Answer: a) Atoll
Explanation: An atoll is a type of lagoon, formed by a ring of coral reefs or islands that encircle a central lagoon.
Q9. What is the main cause of beach formation?
a) Wind erosion
b) Glacial erosion
c) Wave deposition
d) River deposition
Show Answer
Correct Answer: c) Wave deposition
Explanation: Beaches are primarily formed by the deposition of sediment, such as sand or gravel, by waves along the shoreline.
Q10. Which of the following is a feature of a sea cliff?
a) Gentle slope
b) Vertical walls
c) Rocky shore
d) Submerged ridge of sand
Show Answer
Correct Answer: b) Vertical walls
Explanation: Sea cliffs are characterized by their steep, vertical walls, which are formed by the erosive action of waves on the coastline.
Q11. What is the primary agent responsible for the formation of sand on beaches?
a) Wind
b) Tides
c) Waves
d) Rivers
Show Answer
Correct Answer: c) Waves
Explanation: Waves are the primary agent responsible for the formation of sand on beaches, as they transport and deposit sediment along the shoreline.
Q12. Which of the following is a type of sea cave?
a) Littoral cave
b) Lava tube cave
c) Glacier cave
d) Solution cave
Show Answer
Correct Answer: a) Littoral cave
Explanation: Littoral caves are a type of sea cave, formed by the erosive action of waves on rocky coastlines.
Q13. What is the primary force responsible for the formation of sea cliffs?
a) Wind
b) Tides
c) Waves
d) Rivers
Show Answer
Correct Answer: c) Waves
Explanation: Sea cliffs are primarily formed by the erosive action of waves on the coastline, creating steep, rocky features.
Q14. Which of the following is a feature of a sandbar?
a) Vertical walls
b) Gentle slope
c) Rocky shore
d) Submerged ridge of sand
Show Answer
Correct Answer: d) Submerged ridge of sand
Explanation: Sandbars are characterized by their submerged or partially exposed ridges of sand, often formed by the deposition of sediment by currents or waves.
Q15. What is the primary agent responsible for the formation of lagoons?
a) Wind
b) Tides
c) Waves
d) Rivers
Show Answer
Correct Answer: c) Waves
Explanation: Lagoons are primarily formed by the action of waves, which create barriers such as sandbars, coral reefs, or spits that separate the lagoon from the sea.
Q16. Which of the following is a type of beach?
a) Sea cliff
b) Sea cave
c) Sandbar
d) Lagoon
Show Answer
Correct Answer: c) Sandbar
Explanation: A sandbar is a type of beach, formed by the deposition of sediment by waves along the shoreline or offshore.
Q17. What is the primary force responsible for the formation of sea caves?
a) Wind
b) Tides
c) Waves
d) Rivers
Show Answer
Correct Answer: c) Waves
Explanation: Sea caves are primarily formed by the erosive action of waves on rocky coastlines, creating cave-like structures.
