Why Does Granite Weather Slower Than Limestone

Granite has little or no effect to acid rain whilst limestone is slowly eroded therefore granite lasts longer.
Why does granite weather slower than limestone. Granite will weather slower than limestone. Why does granite weather slower than marble. Which do you think will weather at a faster rate sandstone or grantie. 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.
Does soil form faster with limestone than granite. Granite weathers slower compared to marble. Granite is harder and stronger than limestone whilst limestone is easier to shape. This is because granite is composed of four different minerals while marble is basically pure calcite only.
Granite will weather slower than limestone. Hard rocks such as granite weather more slowly than softer rocks such as limestone. Differential weathering happens when softer rocks weathers away and leaves harder more resistant rock behind.
