O: You will be able to explain rocks and the rock cycle.

What is a sedimentary rock?

Sediment in Motion. Weathering The process by which rock is broken down (physical or chemical)

What is Erosion and How is it Different than Weathering  Weathering is the breaking down of rock into smaller pieces.  Erosion is the MOVEMENT of these.

Presentation transcript:

Formation of Sedimentary Rocks

Sediment: small pieces of rock that are moved and deposited by water, wind, glaciers, & gravity. -Range in size from huge boulders to microscopic particles.

Sedimentary Rocks: rocks formed from sediments that “glued” together by mineral growth.

1. Weathering Weathering: produces rock & mineral fragments known as sediment

Types of Weathering 1. Chemical Weathering: occurs when the minerals in a rock are dissolved or chemically changed

2. Physical Weathering: minerals remain chemically unchanged 2. Physical Weathering: minerals remain chemically unchanged. Rock fragments break off

2. Erosion Erosion: The removal & transport of sediment 4 Agents of Erosion Wind Water Gravity Ice/Glaciers

3. Deposition Deposition: When transported sediments are deposited on the ground or sink to the bottom of a body of water
