1 Standard S6E5c. Classify rocks by their process of formation.

2 Formation: Begins with sediment Sediment—particles of materials which come from rocks or living things.

3 Formation: Begins with sediment Sediment—particles of materials which come from rocks or living things. Erosion—process by which water, ice, wind or gravity move weathered rock (sediment) or soil.

4 Formation: Begins with sediment Sediment—particles of materials which come from rocks or living things. Erosion—process by which water, ice, wind or gravity move weathered rock (sediment) or soil. Deposition—process by which sediment settles out of the water or wind carrying it.

5 Formation: Begins with sediment Sediment—particles of materials which come from rocks or living things. Erosion—process by which water, ice, wind or gravity move weathered rock (sediment) or soil. Deposition—process by which sediment settles out of the water or wind carrying it. Compaction—process that presses sediments together.

6 Formation: Begins with sediment Sediment—particles of materials which come from rocks or living things. Erosion—process by which water, ice, wind or gravity move weathered rock (sediment) or soil. Deposition—process by which sediment settles out of the water or wind carrying it. Compaction—process that presses sediments together. Cementation—process in which dissolved minerals crystallize and glue particles of sediment together.

8 Three types: Clastic Chemical Organic

9 Three types: Clastic—formed when layers of sediment are squeezed together Chemical Organic

10 Three types: Clastic—formed when layers of sediment are squeezed together Chemical—formed when dissolved minerals crystallize Organic

11 Three types: Clastic—formed when layers of sediment are squeezed together Chemical—formed when dissolved minerals crystallize Organic—formed from the remains of plants and animals
