Sedimentary Rocks

The most common rock visible on the earth's surface is

• Igneous rock

• Sedimentary rock

• Metamorphic Rock

• Intrusive Rock

Particles of minerals, rock fragments, shells, leaves and the remains of once living things.

• silt

• sediment

• minerals

• extrusive rock

Different sediments have different.

• Textures

• Gravel

• Silt

• Sand

A rock formed from sediments that have been compacted and cemented.

• Metamorphic

• Igneous

• Sedimentary

• Intrustive

During compaction, the weight of the upper layers puts tremendous pressure on the bottom layers compressing the sediments together until the bottom layers slowly turn into

• Hard rock

• Soft rock

• Extrusive rock

• Clastic rock
