sedimentary rocks
any kind of rock
Most of the Earth's crust is made up of igneous rock. But most rock at the surface of the crust is what kind of rock?
Igneous
Sedimentary
Metamorphic
All kinds of rock
Of the three kinds of sedimentary rocks, a rock that is made up of fragments of older rocks is called
Clastic sedimentary rock
Organic sedimentary rock
Chemical sedimentary rock
Lithification is
Breaking down of rock
Transport of rock fragments
Piling rock fragments up into sediment beds
Forming new rocks from sediments
Compaction is
When slowing water lays down sediments to form beds
Squeezing of sediment grains together by the weight of sediments above
Precipitation of minerals that "glue" the sediment grains together
When tectonic plate movement raises buried rocks up to the surface
Cementation is
