MCQs on Fan-shaped plains, Flood Plains and Natural Levees – World Geography
Q1. What type of plain is formed by the deposition of sediment from a river or stream?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: a. Fan-shaped plain
Explanation: Fan-shaped plains, also known as alluvial fans, are formed by the deposition of sediment from a river or stream as it flows out of a mountain range onto a flatter area. The sediment fans out, creating a fan-shaped plain.
Q2. What type of plain is formed by the deposition of sediment during periodic flooding?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: b. Floodplain
Explanation: Floodplains are formed by the deposition of sediment during periodic flooding events. As a river overflows its banks, it deposits sediment onto the surrounding land, creating a flat and fertile area.
Q3. What type of landform is formed by the deposition of sediment along the banks of a river during flooding?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: c. Natural levee
Explanation: Natural levees are formed by the deposition of sediment along the banks of a river during flooding. As the river overflows its banks, it deposits sediment along the edges, creating raised banks that help contain future floods.
Q4. What type of plain is formed by the deposition of sediment at the mouth of a river?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: d. Delta
Explanation: Deltas are formed by the deposition of sediment at the mouth of a river, where the river meets a body of water such as a sea or lake. The sediment accumulates and forms a fan-shaped plain.
Q5. Which of the following is a characteristic of a fan-shaped plain?
a. Steep slopes
b. Highly fertile soil
c. Regular flooding
d. Formation at the mouth of a river
Show Answer
Correct Answer: b. Highly fertile soil
Explanation: Fan-shaped plains, or alluvial fans, are characterized by highly fertile soil due to the deposition of sediment from a river or stream.
Q6. Which of the following is a characteristic of a floodplain?
a. Steep slopes
b. Highly fertile soil
c. Regular flooding
d. Formation at the mouth of a river
Show Answer
Correct Answer: c. Regular flooding
Explanation: Floodplains are characterized by regular flooding, as they are formed by the deposition of sediment during periodic flooding events.
Q7. Which of the following is a characteristic of a natural levee?
a. Steep slopes
b. Highly fertile soil
c. Regular flooding
d. Formation at the mouth of a river
Show Answer
Correct Answer: a. Steep slopes
Explanation: Natural levees are characterized by steep slopes, as they are formed by the deposition of sediment along the banks of a river during flooding.
Q8. Which of the following is a characteristic of a delta?
a. Steep slopes
b. Highly fertile soil
c. Regular flooding
d. Formation at the mouth of a river
Show Answer
Correct Answer: d. Formation at the mouth of a river
Explanation: Deltas are characterized by their formation at the mouth of a river, where the river meets a body of water such as a sea or lake.
Q9. Which type of plain is most likely to be found in an arid or semi-arid region?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: a. Fan-shaped plain
Explanation: Fan-shaped plains, or alluvial fans, are most likely to be found in arid or semi-arid regions, where rivers and streams flow out of mountain ranges onto flatter areas.
Q10. Which type of plain is most likely to be found in a region with high precipitation?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: b. Floodplain
Explanation: Floodplains are most likely to be found in regions with high precipitation, as they are formed by the deposition of sediment during periodic flooding events.
Q11. Which type of plain is most likely to be found along the banks of a river?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: c. Natural levee
Explanation: Natural levees are most likely to be found along the banks of a river, as they are formed by the deposition of sediment during flooding.
Q12. Which type of plain is most likely to be found at the mouth of a river?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: d. Delta
Explanation: Deltas are most likely to be found at the mouth of a river, where the river meets a body of water such as a sea or lake.
Q13. What is the primary force responsible for the formation of fan-shaped plains?
a. Wind erosion
b. Glacial erosion
c. Water erosion and deposition
d. Tectonic activity
Show Answer
Correct Answer: c. Water erosion and deposition
Explanation: Fan-shaped plains, or alluvial fans, are formed primarily by the erosion and deposition of sediment by water from a river or stream.
Q14. What is the primary force responsible for the formation of floodplains?
a. Wind erosion
b. Glacial erosion
c. Water erosion and deposition
d. Tectonic activity
Show Answer
Correct Answer: c. Water erosion and deposition
Explanation: Floodplains are formed primarily by the erosion and deposition of sediment by water during periodic flooding events.
Q15. What is the primary force responsible for the formation of natural levees?
a. Wind erosion
b. Glacial erosion
c. Water erosion and deposition
d. Tectonic activity
Show Answer
Correct Answer: c. Water erosion and deposition
Explanation: Natural levees are formed primarily by the erosion and deposition of sediment by water along the banks of a river during flooding.
Q16. What is the primary force responsible for the formation of deltas?
a. Wind erosion
b. Glacial erosion
c. Water erosion and deposition
d. Tectonic activity
Show Answer
Correct Answer: c. Water erosion and deposition
Explanation: Deltas are formed primarily by the erosion and deposition of sediment by water at the mouth of a river, where the river meets a body of water such as a sea or lake.
Q17. Which type of plain is most likely to be found in a region with low precipitation?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: a. Fan-shaped plain
Explanation: Fan-shaped plains, or alluvial fans, are most likely to be found in regions with low precipitation, as they are formed by the deposition of sediment from a river or stream in arid or semi-arid areas.
Q18. Which type of plain is most likely to be found in a region with high precipitation?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: b. Floodplain
Explanation: Floodplains are most likely to be found in regions with high precipitation, as they are formed by the deposition of sediment during periodic flooding events. High precipitation increases the likelihood of rivers overflowing their banks, leading to the formation and expansion of floodplains.
Q19. Which type of plain is formed by the deposition of sediment from a river or stream in a fan-shaped pattern?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: a. Fan-shaped plain
Explanation: Fan-shaped plains, also known as alluvial fans, are formed by the deposition of sediment from a river or stream as it flows out of a mountain range onto a flatter area. The sediment fans out, creating a fan-shaped plain.
Q20. Which type of plain is formed by the buildup of sediment along the banks of a river during flooding?
a. Fan-shaped plain
b. Floodplain
c. Natural levee
d. Delta
Show Answer
Correct Answer: c. Natural levee
Explanation: Natural levees are formed by the buildup of sediment along the banks of a river during flooding. As the river overflows its banks, it deposits sediment along the edges, creating raised banks that help contain future floods.
