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.

Physical weathering is another important form of denudational process. Choose correct statements regarding it:
(1) It can be broadly divided into 4 types.
(2) Exfoliation occurs only in dry areas.
(3) Frost is the most potent force of weathering in temperate region.
(4) Biotic weathering can take place only if it's preceded by chemical weathering.

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.

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?
