Assertion and Reason Based

Q1: Assertion: Landforms are the result of various geomorphic processes.
Reason: Geomorphic processes include the action of agents like running water, glaciers, wind, and more.
(a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
(b) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
(c) Assertion is true, but Reason is false.
(d) Assertion is false, but Reason is true.

Q2: Assertion: Overland flow can lead to the formation of sheet erosion.
Reason: Sheet erosion occurs when water flows over irregular land surfaces.
(a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
(b) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
(c) Assertion is true, but Reason is false.
(d) Assertion is false, but Reason is true.

Q3: Assertion: Meanders are a type of landform.
Reason: Meanders are formed due to the propensity of water to work laterally on banks and coriolis force.
(a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
(b) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
(c) Assertion is true, but Reason is false.
(d) Assertion is false, but Reason is true.

Q4: Assertion: Stalactites and stalagmites are depositional forms in limestone caves.
Reason: They are formed due to the deposition of calcium carbonate when water carrying it in solution evaporates.
(a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
(b) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
(c) Assertion is true, but Reason is false.
(d) Assertion is false, but Reason is true.

Q5: Assertion: Glaciers can cause significant damage to the landscape.
Reason: The movement of glaciers results in tremendous erosion due to friction caused by the weight of ice.
(a) Both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
(b) Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion.
(c) Assertion is true, but Reason is false.
(d) Assertion is false, but Reason is true.
