Why Does Granite Weather Slower Than Limestone

Granite will weather slower than limestone.

Why does granite weather slower than limestone.

Granite will weather slower than limestone. This is because granite is composed of four different minerals while marble is basically pure calcite only. Granite is harder and stronger than limestone whilst limestone is easier to shape. Hard rocks such as granite weather more slowly than softer rocks such as limestone.

Granite weathers slower compared to marble. Differential weathering happens when softer rocks weathers away and leaves harder more resistant rock behind. Sandstone is a delicate rock. Granite one of the rocks being used in the experiment is known to weather slower than most rocks for example a group of scientist from queen s university in belfast have investigated the weathering of a lighthouse which uses granite as its interior structure.

Which weathers faster sandstone or granite. Sandstone will weather faster because it is softer than granite. Granite has little or no effect to acid rain whilst limestone is slowly eroded therefore granite lasts longer.
