Why Does Granite Erode Slower Than Limestone

Depends on conditions and how coarse or fine grained it is.

Why does granite erode slower than limestone.

In doing this karst scenery is created. The grains of sedimentary rocks can be easily be crumbled off by the factors responsible for erosion. Igneous rocks tend to be harder because of the severe heat and compression they have undergone. Mechanical weathering is when rocks break down into smaller pieces usually caused by change in temperature or natural forces such as tree roots that grow around rocks.

Evidence of chemical weathering can be seen in areas where limestone is exposed to the elements. Sedimentary rocks erode faster. This greatly shows that out of the three rock samples being tested against limestone that granite will most likely show less weathering through the duration of the experiment. Clay is a softer rock than the sandstone so is eroded more quickly the softer rocks erode backwards faster to form sheltered bays which may have beaches.

This is because calcium carbonate which is one of the minerals found in limestone readily reacts with rainwater. This is because the grains in them are further apart to the grains in igneous rocks. Rocks gradually wear away a process called weathering. Which meet the coast at right angles.

Limestone is a rock which is more prone to especially chemical weathering than other types of rocks such as granite. Biological chemical and physical weathering are three types of weathering. But overall it would erode faster than say granite yes. That being said as a geologist i would tell you that given the choice between the two it is shale that erodes more rapidly.

Rainwater can get acidic because of the carbonic acid that it contains. Rainwater erodes the vertical joints and horizontal bedding planes in limestone see image below.
