Sedimentary Rocks

How are Sedimentary Rocks Formed. 1. Weathering: Involves breaking of more giant rocks into smaller ones due to wind and water. Weathering can transform boulders and even mountains into sediments such as sand and mud. Dissolution is a chemical weathering process where partially acidic water wears away solid rocks. 2.

Metamorphic Rocks

Examples of Common Metamorphic Rocks. Here are some examples of metamorphic rocks and their properties: Slate: Derived from shale, a sedimentary rock. Slate has a fine grain and ability to be split into thin sheets.. Schist: Characterized by its sheet-like structure and formed typically from mudstone or shale.

Sedimentary Rocks Formed | What Type of Rock is Chalk

Chalk is formed out of superfine sediment called 'ooze'. The formation of chalk starts with the death of the shells of marine animals, called 'foraminifera', marine algae, or other organisms that live at the bottom of the ocean, or in the waters above. The remains of these dead organisms collect together and form the sediment, ooze.
