igneous sedimentary Metamorphic rock

• Molten rock above the surface is called Lava
• Erosion is the overall process of the breakup of rock and their transport away from their original location
• Chemical weathering happens when rain falls on rocks
• Biological weathering happens when plants and Animals break up rocks.
• Compaction the weight of sediments above squashes tother the sediments below
• Sedimentary rocks are made from different processes starting with weathering erosion transportation deposition compaction cementation
• When magma or lava cools down to a solid, crystals are formed
• The longer it takes for the magma or lava to cool, the larger the crystals are
