🗑
metamorphic rock   forms when heat, pressure, or fluids act on igneous, sedimentary, or other metamorphic rock to change its form or composition or both  
🗑
compaction   process that forms sedimentart rocks when layers of sediments are compressed by the weight of the laers above them

🗑
rock cycle   model that describes how rocks slowly change from one form to another through time  
🗑
granitic   describes generally light-colored, silica rich igneous rock that is less dense than basaltic rock  
🗑
basaltic   describes dense, dark-colored igneous rock formed from magma rich in magnesium and iron and poor in silica  
🗑
sediment   loose materials, such as rock fragments, mineral grains, and the remains or once-living plants and animals that have been moved by wind, water, ice, or gravity  
🗑
igneous rock   rock formed when magma or lava cools and hardens  
🗑
sedimentary rock   forms when sediments are compacted and cemented together or when minerals form from solutions
