2. Tick the correct answer.
Answers
Answer:
(i) Plates move due to tecronic recurrence in the lithospheric region.
(ii) Exogenic forces are external geomorphic forces which are slow and make changes on the earth's surface whereas, Endogenic forces are internal geomorphic forces which are generally fast to disorient the surface.
(iii) Erosion can be of many types but their main work is to disorient the landforms on the surface.
(iv) Flood plains are formed when a uneven land surface beside a river gets flooded and levelled up as a plainland. This occurs due to the breaking of multiple embankments on the side of the river.
(v) Sand dunes are structure in a desert region which are formes due to massive accumulation of sand from various areas.
(vi) Beaches are formed when the sand, gravel and various other particles are washed up and accumulate on a bank thus forming a sandy area on the coastline.
(vii) Ox bow lakes are formed when a winding river gets broken up due to maximum curvature upon the river course and thus the river acquires a straight path again.

(1) the plates move because of the movement of the molten magma inside the earth.
(2) the force which act in the interior of the earth are called endogenic force but the force which act in the exterior of the earth is called exogenic force.
(3) the wearing the landscape by different agents like water wind and ice called erosion.
