Weathering of Rocks

Which is one of the major constituents of the Earth’s crust?

• Rocks

• Soil

• Magma

• Silt

Outer layer of rocks peeling off is the process of:

• Carbonation

• Weathering

• Exfoliation

• Hydrolysis

If you leave a can of soda in the freeze for a long time what will happen and why?

• The can will expand and lose its shape as water expands on cooling.

• The can will shrivel as water will shrink on turning into ice.

• The can will remain in the same shape as water remains the

  same volume when frozen.

• None of the above

This process makes rocks less resistant to weathering:

• Carbonation

• Grafting

• Exfoliation

• Hydrolysis

What is Mass-movement or Mass-wasting

• Geomorphic process by which soil,sand and rocks move downslope typically as a mass

• The weathering of rocks into sediment

• The process of rock formation through plate tectonics

• The movement of water through a drainage basin.

What is the process of oxidation?

• When minerals come in contact with oxygen, they become less resistant to weathering.

• When rainwater reacts with carbon dioxide, it forms mild carbonic acid.

• When animals dig up the minerals from the soil, it makes it vulnerable to weathering.

• None of the above

Which of the following weathering cannot disintegrate rocks unless outside forces act on them?

• Chemical Weathering

• Biological Weathering

• Mechanical Weathering

• None of the above
