Why Does Granite Erode Slower Than Limestone

Limestone has long fascinated earth scientists because of its rich fossil.

Why does granite erode slower than limestone.

Limestone has two origins. 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. Granite has little or no effect to acid rain whilst limestone is slowly eroded therefore granite lasts longer. Granite will weather slower than limestone.

4 limestone problems that you might come across and how to avoid them. Which meet the coast at right angles. 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.

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. 1 biogenic precipitation from seawater the primary agents being lime secreting organisms and foraminifera. 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. Travertine tufa caliche chalk sparite and micrite are all varieties of limestone.
