In Western plateau region, the vast areas of broken rock and stone, where winds have removed all the loose, light material, are known as the _______.
Regarding Abrasio, a weathering process, choose the correct statement(s):
(1) It is a wearing down process related only to fluvial erosion.
(2) Friction is the prime force responsible for abrasion.
(3) Attrition is same as abrasion in all respects.
Geomorphically, what all processes lead to sculpting a landscape?
(1) Weathering
(3) Deposition.
Match the following
List I(Phases of Denudation) | List II(Description) |
---|---|
(A) Weathering | (1) disintegration of rocks |
(B) Erosion | (2) wearing away by agents of denudation |
(C) Transportation | (3) removal of eroded material to new place |
(D) Deposition | (4) dumping at some place where accumulation takes place. |
Salinisation occurs when the irrigation water accumulated in the soil evaporates, leaving behind salts and minerals. What are the effects of salinization on the irrigated land?
With respect to chemical weathering a denudational process, choose the correct statements.
(1) It may weaken or entirely dissolve certain constituent of rocks.
(2) In granite, which is made up of quartz feldspar and mica, feldspar easily weathers away.
(3) Loosened material, as in example of granite, quartz and mica are eroded.
(4) Weathered material as in case of granite, feldspar forms regolith, basis of soil.
Denudation involves four processes, which take place simultaneously. On what factors are these processes dependent to sculpt a landform?
(1) Nature of relief (2) Structure of rocks
(3) Local climate (4) Interference by man
Surface run-off becomes stream when water flows from certain height down slope under impact of gravity. Which of the following form streams?
(1) Perennial (2) Intermittent
(3) Ephemeral (4) Seasonal
Ground water is an agent of erosion, transportation and deposition. Regarding ground water, pick correct statements.
(1) Water filling up joints and pores-spaces is ground water.
(2) Groundwater plays an important role in weathering and mass movement.
(3) It re-enters hydrological cycle as springs.
(4) Amount of water available as ground water depends upon climate, season and nature of rocks.
Regarding mass movement, choose the correct statements.
(1) Movement of weathered material down slope.
(2) Gravitational force of Earth is the reason for mass movement with multiple triggers.
(3) It is dependent upon gradient of slope, weight of weathered debris and presence of any trigger (lubricating agent or vibration).
(4) There are 3 types of mass movement.
Fluvial erosion is one of the most important exogenetic processes. On what factors does it depend?
(1) Channel gradient (2) Volume of water
(3) Velocity of flow (4) Water discharge (5) Sediment load
