1. Which of the following is an example of mass movement?
a) Delta formation
b) Landslide
c) Meander formation
d) Sand dune formation
Answer: (b) Landslide
Mass movement (Mass Wasting) refers to the downslope movement of rock or soil under the direct influence of gravity.
2. Which factor is the main driving force for mass movement?
a) Wind
b) Running water
c) Gravity
d) Temperature
Answer: (c) Gravity
Gravity is the fundamental force responsible for all types of mass movement.
3. Soil creep is characterized by:
a) Rapid movement of rocks
b) Slow downhill movement of soil
c) River deposition
d) Wind erosion
Answer: (b) Slow downhill movement of soil
Soil creep is the slowest form of mass movement and is common on gentle slopes.
4. Which depositional landform is formed by a river at its mouth?
a) Canyon
b) Delta
c) Gorge
d) Waterfall
Answer: (b) Delta
A delta forms due to the deposition of sediments where a river enters a sea or lake.
The Sundarbans Delta is the world's largest delta.
5. Consider the following statements:
1. Moraines are depositional features of glaciers.
2. Loess is deposited by wind.
3. Natural levees are formed by river deposition.
Which of the above statements are correct?
a) 1 and 2 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2, and 3
Answer: (d) 1, 2, and 3
All three statements are correct.
6. Which depositional feature is formed by wind?
a) Delta
b) Moraine
c) Sand dune
d) Fjord
Answer: (c) Sand dune
Sand dunes are the most characteristic depositional landforms of arid regions.
Loess is wind-deposited fine silt and is highly fertile.
7. Natural levees are formed by:
a) Wind deposition
b) Glacial deposition
c) River deposition
d) Marine deposition
Answer: (c) River deposition
During floods, coarser sediments are deposited near river banks, forming natural levees.
8. Which of the following is NOT a depositional landform?
a) Delta
b) Moraine
c) Sand dune
d) Canyon
Answer: (d) Canyon
Canyon is an erosional landform produced by river action.
Sand dunes are the most characteristic depositional landforms of arid regions.
Loess is also a depositional landform, which is formed by wind. It is a deposit of fine silt and is highly fertile.
9. Which glacial depositional landform consists of unsorted sediments?
a) Esker
b) Drumlin
c) Moraine
d) Outwash plain
Answer: (c) Moraine
Moraines are deposits of unsorted glacial debris known as till.
Drumlins are streamlined hills composed of glacial till.
10. Which coastal depositional landform connects an island to the mainland?
a) Lagoon
b) Tombolo
c) Spit
d) Stack
Answer: (b) Tombolo
A tombolo is formed by wave deposition joining an island to the mainland.
