Sedimentary Rock Classification

Sedimentary rocks are formed by

• Cooling of lava or magma
• Heat and pressure
• Compacting and cementing

What is the breaking down of rocks?

• Weathering
• Clastic
• Vesicular

What is deposition?

• Pieces of sediment come to rest on a surface
• Movement of sediment
• Breaking down of sediment 

Small pieces of rock are also called

• sediment
• coal
• organic matter
• erosion

Wind, water, ice and gravity carry sediments away

• weathering*
• deposition
• erosion
• cementation

When the weight of new  sediment layers is deposited on top of older layers

• erosion
• compaction
• pressure
• weathering

The process of layers become stuck together forming sedimentary rocks

• sticking
• pressuring
• cementation
• deposition

Classify each sedimentary rock as either Clastic, Organic, or Chemical. 
Sandstone

• Organic
• Chemical

Classify each sedimentary rock as either Clastic, Organic, or Chemical.
Limestone made from shells

• Clastic
• Organic
• Chemical

Classify each sedimentary rock as either Clastic, Organic, or Chemical. 
Conglomerate

• Clastic
• Organic
