Answer:

Physical Weathering-

Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. Ice wedging. Ice wedging causes many rocks to break. Plant roots. Plant roots can grow in cracks.

Chemical Weathering-

The reaction of carbon dioxide gas in rainwater can produce carbonic acid that dissolves some minerals, especially limestone. Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering. Chemical weathering also occurs when iron in rock oxidizes or rusts.

Weathering can be defined as breaking down rocks into smaller rocks by the effects of agents of erosion, chemical agents, and physical agents.

Examples of chemical weathering: Carbonation, Hydrolysis, and Oxidation

Examples of physical weathering: Expansion due to the effects of heat, Abrasion, Freezing

Chemical weathering can be defined as the breaking down of rocks due to chemical reactions. This affects the chemical composition of the rocks.

Physical weathering can be defined as the effects of physical agents on rocks such as wind, temperature e.t.c that result in the breaking down of rocks. In Physical weathering, the chemical components of the rocks do not change.

Examples of chemical weathering are:

  • Oxidation: The breaking down of rocks due to the effects of oxidation

  • Hydrolysis: The dissolving of the mineral components of a rock due to its interaction with water.

  • Carbonation: This is the reaction between the rock and acidic rain which contains carbonic acid.

Examples of physical weathering are:

  • Expansion due to the effects of heat

  • Abrasion: When rocks come in contact with other rocks, this can lead to physical weathering.

  • Freezing thawing: When water gets frozen in rocks, when the ice starts to melt(thaw) the results in the breaking down of rocks as well.
