Which types of rock can be weathered to form sediment?

All forms of rock can weather and form sediment that is carried by water, wind or glaciers. Some just break down more easily than others. Example One is fine grained igneous basalt (lava) that is very difficult to break down. Now think of a black sand beach. That is an example of sediment. Another example is a very soft limestone that was originally formed from sediment itself. But through heat and pressure was turned into rock. It may erode very easily and be carried away by a stream or a glacier. We don't often consider how the things on our Earth are all related. We think of an ocean and a mountain range as two very distinct and separate things. But it is more likely that the mountain range was once the floor of an ancient sea. And the tectonic plates collided and one slid underneath the other and all the shells and dirt and bones that collected on the bottom of the sea for millions of years was transformed into a rock. The seas, the mountains, the skies, the people and animals. All just parts of a system that are all related.
