Question

What happens when sedimentary rock becomes metamorphic rock?


A.


Sedimentary rock undergoes heat and pressure to form metamorphic rock.


B.


Sedimentary rock cools and solidifies to become metamorphic rock.


C.


Sedimentary rock weathers, erodes, compacts, and cements to become metamorphic rock.


D.


Sedimentary rock melts and crystallizes to become metamorphic rock.

Answer 1

anyone?

Answer 2

Sedimentary rock can be metamorphosed by: a) exposure to heat by close proximity to a heat source such as a plutonic intrusion; b) from deep burial pressures; c) from directed pressure and heat from mountain building processes; d) chemical changes from exposure to heated fluids, the fluids heated by a plutonic intrusion. Metamorphism of sedimentary rocks can result in a realignment of mineral constituents, recrystallization, or new chemical compositions.

Answer 3

Through weathering and erosion of the metamorphic rock. The metamorphic rock, exposed to weathering processes at the surface, breaks into smaller pieces. Erosional processes transport these pieces to a place of deposition where they build up, layer on layer. Eventually the compaction caused by the weight of the sediments above reduces the amount of space and water between particles. In this process of rock formation known as lithification, cementing minerals are formed out of the slowly disappearing fluids, which are saturated with mineral components. Once cemented together, it is now considered sedimentary rock.

Answer 6

Sedimentary rocks are formed by layers of sediment (dirt, rock particles, etc.) being mixed and compressed together for extended periods of time. Common examples of these rocks are limestone, sandstone, and shale. Sedimentary rocks often have lots of fossils in them because plants and animals get buried in the layers of sediment and turned into stone.

Metamorphic rocks are a combination of rock types, compressed together by high pressure and high heat. They usually have a more hard, grainy texture than the other two types. Schist, slate, and gneiss (pronounced like 'nice') are metamorphic rocks.

Answer 16

Which describes granite and basalt?


A.


Granite is a coarse-grained intrusive igneous rock, while basalt is a fine-grained extrusive igneous rock.


B.


Both granite and basalt are fine-grained intrusive igneous rocks.


C.


Granite is a coarse-grained extrusive igneous rock, while basalt is a fine-grained intrusive igneous rock.


D.


Granite is a fine-grained extrusive igneous rock, while basalt is a coarse-grained intrusive igneous rock.

Answer 17

the answer for the first question is _C_.
the Igneous rock erodes, then compacts, and cements to become sedimentary rock.
