Explanation:
When sandstone is overlaid by layers and layers of sediment, it becomes subject to enormous pressure and temperature beneath the layers and its grain structure begins to change. The force of compactness causes grain structure and size to reform. This is called metamophism., The sandstone becomes a new rock called quartzite. The two rocks will have different properties. Quartzite will have larger crystals and will be hard and smooth while sandstone will be coarse and soft.
