Rocks

In the simple rock-cycle diagram, which processes along path X would change the schist (stage C) directly into a pile of sediments (stage A)?

• uplift, weathering, and erosion of the schist

• cementing of sediment grains followed by compaction

• melting of the schist followed by cooling

• heat and/or pressure applied to the schist

Which rock formation was originally limestone?

• Manhattan schist

• Fordham gneiss

• Inwood Marble

• Palisades sill

Which statement is supported by information in the rock cycle diagram in the Earth Science Reference Tables?

• Metamorphic rock results directly from melting and crystallization.

• Sedimentary rock can only be formed from igneous rock.

• Igneous rock always results from melting and solidification.

• All sediments turn directly into sedimentary rock.

What is the main difference between metamorphic rocks and most other rocks?A) B).C) D) .

• Many metamorphic rocks contain a high amount of oxygen-silicon tetrahedra

• Many metamorphic rocks exhibit banding and distortion of structure.

• Many metamorphic rocks have an organic composition

• Many metamorphic rocks contain only one mineral.

Which rocks would most likely be separated by a transition zone of altered rock (metamorphicrock)?

A) B) C) D)

• sandstone and limestone

• shale and sandstone

• granite and limestone

• conglomerate and siltstone

metamorphic rocks result from the

• erosion of rocks

• recrystallization of rocks

• cooling and solidification of molten magma

• compression and cementation of soil particles

Which characteristic determines whether a rock is classified as a shale, a siltstone, a sandstone, or a conglomerate?

• the absolute age of the sediments within the rock

• the mineral composition of the sediments within the rock

• the particle size of the sediments within the rock

• the density of the sediments within the rock

Which statement best describes a general property of rocks?

• Most rocks have a number of minerals in common.

• Most rocks are composed of a single mineral.

• All rocks contain fossils.

• All rocks contain minerals formed by compression and cementation.
