• Sedimentary rock
• Soil

What type of rock forms when water evaporates and mineral crystallize

• Metamorphic
• Evaporite
• Sedimentary
• Igneous

What takes place when existing rocks are changed by extreme temperature, pressure, or fluids?

• Weathering occurs.
• Sedimentation occurs.
• Metamorphism occurs.
• Erosion occurs.
