ROCKS- Introduction

solid rock. Sandstone is a common sedimentary rock. It is not unusual to find fossilized seashells in sandstone. Sandstone is easy to identify. When you rub it on the ground grains of sand come off. Shale is another sedimentary rock, formed from clay. Limestone forms from the shells of long-dead sea creatures. White chalk is made from limestone.

is it possible for sedimentary rock to form into another

Dec 15, 2021 · A metamorphic rock is not really considered a sedimentary rock even if it is a metasediment, although there is the issue that even lithification is a low grade metamorphism (a stage of diagenesis, which itself is perhaps a form of metamorphism depending on what you mean by the word), if you get right down to it, so any sedimentary "rock" is not
