What does granite turn into after weathering and erosion.

It consists of four main mineral compounds. 5 2 weathering and erosion. The swelling of these clay minerals as they abosorb water further weathers the granite and biotite minerals in particular also undergo oxidiation leading to the reddish color of grus. Granite is extremely hard and less affected by the freeze thaw cycle the forces of abrasion and the surface exfoliation processes that are all a part of physical weathering.

That is one type of mineral changes into a different mineral. Chemical weathering is different from mechanical weathering because the rock changes not just in size of pieces but in composition. Weathering is a process that turns bedrock into smaller particles called sediment or soil. The dissolved calcium carbonate may drip into underground caves hollowed out from the action of weathering.

The low relief also reduced erosion rates prior to glaciation and allowed deep weathering profiles to develop. Two of these are types of feldspar a group of silica compounds that constitute the most abundant mineral group on earth. These cracks allow water to pass easily through the rock. In the cairngorms chemical weathering of the granite is restricted in its extent and depth.

Weathering and erosion slowly chisel polish and buff earth s rock into ever evolving works of art and then wash the remains into the sea. When it gets cold the water turns into ice and expands. The processes are definitively independent but not. What happens when a rock like granite undergoes the processes of weathering what does it turn into.

Chemical weathering works through chemical reactions that cause changes in the minerals. Chemical weathering is the other important type of weathering. A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location. The exposures provided by glacial cliffs demonstrate that the granite is generally covered only by a thin regolith.

Many horizontal and vertical cracks run through limestone. Water acts as an acid when it contacts calcium carbonate dissolving the limestone. Basically it is the granular disintegration or grusification of granite due to the hydration of feldspar and biotite minerals which break down into clays. Ice weathering is when water seeps into a rock.

Mechanical weathering includes pressure expansion frost wedging root wedging and salt expansion chemical weathering includes carbonic acid and hydrolysis dissolution and oxidation. Such as granite weather more slowly.
