Question
Which of the following factor affects the rate of weathering?
- Water
- Ice
- Chemicals
- All of these
Hint:
Weathering is of three types physical, chemical and biological.
The correct answer is: All of these
The correct option is d) All of the above.
- Water is the main factor behind both physical and chemical weathering, but atmospheric oxygen and carbon dioxide and biological activity are also important.
- Precipitation and temperature can affect the weather. High temperatures and increased precipitation accelerate chemical weathering. Chemical weathering is the process by which minerals in rocks turn into clay, oxidize, or simply dissolve.
- Liquid water penetrates cracks and crevices in rocks. When the temperature drops enough, the water freezes. When water freezes, it expands. Ice works like a wedge. Slowly widen the crack and split the rock.

______ is the shaping of the land present below the moving glacier.
The correct option is B)Glacial erosion.
Glacial erosion involves the removal and transport of bedrock and sediments through three major processes: quarrying (picking), abrasion and meltwater. Mining involves two separate processes: crushing the bedrock beneath the glacier and carrying the crushed rock along. Erosion by glacial meltwater under glaciers is the result of mechanical or chemical processes.

_________ causes weathering of rocks in glacier.
The correct option is b)Ice.
Ice wedges are defined by the physical weathering of rock, where the surface within rock cracks fills with water, freezes, and eventually expands. Widening cracks and build-up of pressure within the rock cause it to expand and fracture. Ice wedging is also called frost wedging.
