Why Does Granite Weather Slower Than Limestone

Hard rocks such as granite weather more slowly than softer rocks such as limestone.

Why does granite weather slower than limestone.

Which do you think will weather at a faster rate sandstone or grantie. Granite has little or no effect to acid rain whilst limestone is slowly eroded therefore granite lasts longer. Does soil form faster with limestone than granite. Why does granite weather slower than marble.

This is because granite is composed of four different minerals while marble is basically pure calcite only. 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. Differential weathering happens when softer rocks weathers away and leaves harder more resistant rock behind. Granite weathers slower compared to marble.

Sandstone is a delicate rock. Sandstone will weather faster because it is softer than granite. Granite is harder and stronger than limestone whilst limestone is easier to shape.
