Why Does Granite Erode Slower Than Limestone

Limestone has two origins.

Why does granite erode slower than limestone.

Granite has little or no effect to acid rain whilst limestone is slowly eroded therefore granite lasts longer. Limestone is much softer more porous and more susceptible to this is primarily due to the chemical composition of the rocks. Travertine tufa caliche chalk sparite and micrite are all varieties of limestone. Secondly the structure of granite is that of.

Limestone because of its mineral property which is composed of mainly calcite which is weaker than granite and the minerals it usually is made up of quartz feldspar mica. Limestone because of its mineral property which is composed of mainly calcite which is weaker than granite. Which meet the coast at right angles. Granite will weather slower than limestone.

Limestone is a rock which is more prone to especially chemical weathering than other types of rocks such as granite. What weathers faster a granite or limestone. Granite is harder and stronger than limestone whilst limestone is easier to shape. This is because calcium carbonate which is one of the minerals found in limestone readily reacts with rainwater.

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. And 2 mechanical transport and deposition of preexisting limestones forming clastic deposits.
