Rocks

The process in which dissolved minerals crystallize and glue sediment together.

• cementation
• deposition
• organic rock

How is sediment classified/grouped?

• By color
• By hardness
• By size

Sedimentary rocks are formed by

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

How is sediment formed?

• Weathering and Erosion
• Melting
• Pressure

What is deposition?

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

Fossils are made by

• Plants dying
• Animals or plants are imprinted on a layer of sedimentary rock
• Breaking down of rocks

Rock made of layers of compressed sediments

• metamorphic rock
• igneous rock
• sedimentary rock
• school house rock

What are the types of sedimentary rock?

• Igneous; Metamorphic; Sedimentary

• Clastic; Igneous; Sedimentary

• Chemical; Clastic; Inorganic

• Organic; Clastic; Chemical

Chemical rocks are...

• Made from heat

• Made when water evaporates and minerals crystallize

• Made from dead animals/plants

• Made from pieces of other rocks

Organic rocks are...

• Made from heat

• Made when water evaporates and minerals crystallize

• Made from the remains of dead animals/plants

• Made from pieces of other rocks
