|---|---|---|---|---|---|
| basaltic | describes dense, dark-colored igneous rock that forms when magma being forced upward towards Earth's crust cools slowly and solidifies underground
🗑
|
||||
| lava | molten rock that flows from volcanoes onto Earth's surface
🗑
|
||||
| cementation | sedimentary rock-forming process where sediment grains are held together by natural cements that are produced when water moves through rock and soil
🗑
|
||||
| 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 sedimentary rocks when layers of sediments are compressed by the weight of the layers above them
🗑
|
||||
| nonfoliated | describes metamorphic rock whose mineral grains grow and rearrange but generally without layers
🗑
|
||||
| extrusive | describes fine-grained igneous rock that forms when magma cools quickly at or near Earth's surface
🗑
|
||||
| rock | a mixture of minerals, rock fragments, volcanic glass, organic matter, and/or other natural materials
🗑
|
||||
| foliated | describes metamorphic rock whose mineral grains line up in parallel layers
🗑
|
||||
| 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
🗑
|
||||
| sediment | loose materials, like rock fragments, mineral grains, and remains of once-living things, 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
🗑
|
||||
| intrusive | describes a type of igneous rock that generally contains large crystals and forms when magma cools slowly beneath Earth's surface
🗑
