Why Does Granite Erode Slower Than Limestone

Granite will weather slower than limestone.

Why does granite erode slower than limestone.

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. Granite has little or no effect to acid rain whilst limestone is slowly eroded therefore granite lasts longer. Secondly the structure of granite is that of. Which meet the coast at right angles.

This is because calcium carbonate which is one of the minerals found in limestone readily reacts with rainwater. And 2 mechanical transport and deposition of preexisting limestones forming clastic deposits. Travertine tufa caliche chalk sparite and micrite are all varieties of limestone. Limestone has two origins.

Limestone has long fascinated earth scientists because of its rich fossil. Granite is harder and stronger than limestone whilst limestone is easier to shape. 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. What weathers faster a granite or limestone.

Limestone is much softer more porous and more susceptible to this is primarily due to the chemical composition of the rocks. Limestone is a rock which is more prone to especially chemical weathering than other types of rocks such as granite.
