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 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. Secondly the structure of granite is that of. 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. Limestone because of its mineral property which is composed of mainly calcite which is weaker than granite. What weathers faster a granite or limestone. Limestone has two origins.

Limestone is a rock which is more prone to especially chemical weathering than other types of rocks such as granite. Granite has little or no effect to acid rain whilst limestone is slowly eroded therefore granite lasts longer. 1 biogenic precipitation from seawater the primary agents being lime secreting organisms and foraminifera. Travertine tufa caliche chalk sparite and micrite are all varieties of limestone.

And 2 mechanical transport and deposition of preexisting limestones forming clastic deposits. Granite will weather slower than limestone.
