One of the most common types of physical weathering iswedging. Wedging occurs when a substance finds its way into cracks or holes in rock and expands outward. This widens these cracks and holes, and can cause rock to split apart; this may also occur to exposed brick. Freezing water, crysta...
Biological weathering includes the effects of plant and animals on rocks and minerals. For example, an animal inadvertently kicks a rock down a hill where it breaks upon landing. Or when a bit of moss or lichen attach itself to its new host, a shaded rock and begins to eat away at the ...
types of physical weathering: unloading and expansion: removal of overlying rock load because of continued erosion causes vertical pressure release with the result that the upper layers of the rock expand producing disintegration of rock masses. fractures will develop roughly parallel to the ground ...
