    Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.

    Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.

    Biological weathering is the weakening and subsequent disintegration of rock by plants, animals and microbes. … As this process continues, holes and gaps continue to develop on the rock, exposing the rock further to physical and chemical weathering.

    The above explained points are all associated with weathering in all forms.

  1. Weathering is the process by which rocks and minerals breakdown and dissolve on the Earth’s surface. Erosion moves this particles and minerals away. Water , acids, salts, animals and changes in temperature are agents of weathering and erosion.

    Sill, also called sheet, flat intrusion of igneous rock that forms between preexisting layers of rock. Sills occur in parallel to the bedding of the other rocks that enclose them, and, though they may have vertical to horizontal orientations, nearly horizontal sills are the most common.

    dike is a flat body of rock that cuts through another type of rock. Dikes cut across the other type of rock at a different angle than the rest of the structure. Dikes are usually visible because they are at a different angle, and usually have different color and texture than the rock surrounding them.

    Sedimentary rocks has the word sediment in it. The word sediment means remains, residue, accumulation and so on. A sedimentary rock is therefore accumulation of other smaller rocks and other organisms on the upper layer of the earth surface to form a rock. Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth’s surface.

What is folding in landforms?

What is folding in landforms?

  1. When there is compression of rock layers, there is a bending of the earth’s crust this causes folds to occur. When forces act towards each other i.e when plates collide , compression occurs. This compression leads to folds.

  1. As the plates move about, bending and twisting within them products fractures called faults. If the faults movement is horizontal, such as on the San Andreas fault, the grinding up of the rock in the vicinity of the fault may look susceptible to weathing and erosion.
