This rock is made of salts left behind when a shallow sea evaporated. What type of sedimentary rock is it?

• clastic sedimentary rock
• chemical sedimentary rock
• organic sedimentary rock

What causes the pressure necessary to form sedimentary rocks?

• chemicals in the rock

• temperatures inside the Earth

• weight from sediments above

• water flowing over rock

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

• erosion
• compaction
• pressure
• weathering
