Geomorphic Processes

This is the correct answer because glaciers move because of the force of gravity.

This is the correct answer. Fjords are the very deep glacial troughs filled with sea water and making up shorelines in high latitudes.

This is the correct answer, as both these statements are correct.

This is the correct answer. Very coarse materials like boulders and blocks along with some minor fractions of rock debris carried into the melted ice stream in the summer settle in the valley of ice beneath the glacier, and after the ice melts can be found as a sinuous ridge called esker.

Some amount of rock debris small enough to be carried by melt water streams is washed down and deposited. Such glacio-fluvial deposits are called out wash deposits.

This is correct, as all the statements are incorrect.

This is the correct answer,  as both these statements are correct. Drumlins are smooth oval shaped ridge-like features composed mainly of glacial till with some masses of gravel and sand. The long axes of drumlins are parallel to the direction of ice movement. The drumlins form due to dumping of rock debris beneath heavily loaded icethrough fissures in the glacier. The stoss end gets blunted due to pushing by moving ice. Drumlins give an indication of direction of glacier movement.

Soil conservation is the practice of preventing soil loss from erosion or reduced fertility. The primary goal is protecting soil against erosion caused by water, wind, and other factors while maintaining its productivity for future use.

Eskers are long winding ridges of sand and gravel, while drumlins are oval-shaped hills - both are depositional landforms created by glaciers. They form from the deposition and movement of glacial sediment and ice.

Erosion is the removal and transport of soil particles by water, wind, or other natural agents. Corrosion refers to chemical degradation of materials (usually metals), not soil removal. Translocation involves movement within soil, and salination is salt accumulation.

Moraines are the rock debris and sediment carried and deposited by glaciers. Alluvium refers to water-deposited sediment, meanders are river bends, and nodules are concentrated mineral masses - none of these are glacier-transported materials.

Evaporation (B) is the correct answer - it is the process by which water changes from liquid to vapor, removing moisture from soil. Condensation (A) is the opposite process (gas to liquid). Precipitation (C) is water falling from atmosphere to ground. Transpiration (D) is water loss from plants, not directly from soil.

Water and wind are the primary natural agents that cause soil erosion by carrying away soil particles from one location to another. Water erosion occurs through rainfall and runoff, while wind erosion happens in dry areas with loose soil. The other options list factors that influence soil but are not the primary agents of erosion.

Soil erosion is defined as the removal or transportation of topsoil by natural forces like water and wind. Soil pollution refers to contamination, not removal. Soil profile refers to soil layers, and soil moisture is about water content - none of these mean removal of topsoil.

Evaporation is a process in which water in its liquid form is changed into gaseous form by the process of boiling. Water present on the earth’s surface in various water bodies changes into water vapours by the process of evaporation and thus, gets evaporated from the earth’s surface into the atmosphere.
