Rocks Flashcards
How does igneous rock form
melting and solidifaction
How does sedimentary rock form
pieces of rock compacted together
How does metamorphic rock form
heat and pressure
How does sediments form
igneous rock
Erode/erosion-
transporting
Weathering-
wear down/ break down
What are 2 ways that rocks are naturally eroded?
Rivers, glaciers, oceans (water), and wind
When you weathered the candy, the pieces were no longer the same size or shape as before. What are 2 different ways that rocks are weathered in nature?
Rain and wind weather rocks in nature.
How is sediment put together to form sedimentary rock?
Compression
Compaction
Cementation (Sedimentation)
How was the process of forming sedimentary rock different from that of making metamorphic rock?
heat (without melting) and pressure
Cementation-
Sedimentation
Intrusive-
cooling inside Earth
Extrusive-
cooling on the surface
2 characteristics
Sedimentary
-pieces of rock
-layers
2 characteristics
Metamorphic
-wavy material
-solid
2 characteristics
Igneous
-mixed colors and consistent
-solidification
