Write 3 Examples of Chemical weathering and Physical weathering

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.
