Can clastic rocks be sedimentary rocks?
No, the Grand Canyon is a river valley eroded into rock - as such it is an absence of rock. However the rocks through which the river has eroded are, in the main, of sedimentary origin.
Where can you find metamorphic rock?
== == Metamorphic rocks can be found at great depths within the Earth's crust, at the base of mountains, or in contact zones where plutonic intrusions have metamorphosed the host rock via high temperatures. Metamorphic rocks can indeed be found at great depths within the crust, but for a rockhound, finding them elsewhere is not a problem. Areas that have experienced previous glaciation (as far south as Central Illinois in the last period of glaciation) are full of metamorphic erratic rocks, transported and dropped by the ice. Visitors to Colorado can find an abundance of metamorphic rocks in the eroded Rocky Mountains, many dating to the Pre-Cambrian. Californians, too can collect meta's in eroded mountains and in formations such as the San Onofre Breccia. No glaciation? Look around eroded mountains.
Are unakite rocks Sedimentary rocks Metamorphic rocks or Igneous rocks?
metamorphic
Can metamorphic rocks be sedimentary or igneous rocks?
there are several ways such as heat & pressure, melting, chemical weathering, compression, compaction & cementation, but it depends on the kind of rock it is for what process it has to go through. -Cutegirl99
Metamorphic rocks that don't have layers?
Sedimentary rocks have layers, not metamorphic rocks.
How do noncomformities form?
A nonconformity is a place where sedimentary rocks are found on top of eroded igneous or metamorphic rocks. The igneous or metamorphic rocks can be pushed up by forces inside the Earth. Then, erosion can remove some of the rock. Later, sediment may be deposited on top of the eroded rock.
What occurs when sedimentary rocks are deposited on top of uplifted and eroded metamorphic or igneous rocks?
An uncomformity will occur in the rock record.
What classification or kind of rocks results when rocks eroded from higher elevations accumulate at lower elevations?
asial sedimentary igneous metamorphic
3 main categories of rocks?
Igneous--those that form directly from a molten state. Sedimentary--those that form from eroded particles of various sizes from other rocks. Metamorphic--igneous and sedimentary rocks, and sometimes metamorphic rocks, that undergo a transformation from heat and/or pressure.
What can happento a sedimentary rock once it is formed?
Sedimentary rocks can be eroded into sediments and form sedimentary rocks again, they can melt and become igneous rocks, and they can undergo extreme heat and pressure and become metamorphic rocks.

Where can you find metamorpic rock?
A metamorphic rock is the type of rock that is formed when pressure or heat change other rocks. Existing rock types can be changed by movements of the Earth that causes them to be squeezed or buried.
Are metamorphic rocks only formed by igneous rocks?
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
Why rocks are formed?
eroded rock (from igneous, metamorphic, or sedimentary) settled. they compact together to form a rock. the rock that they form is known as sedimentary rock
Are unakite rocks Sedimentary rocks Metamorphic rocks or Igneous rocks?
metamorphic
What forces are in the rock cycle?
Sedimentary rocks are formed when other rocks (igneous, metamorphic, or sedimentary) are weathered and eroded and their sediments are compacted and cemented together. Metamorphic rocks can be formed when heat and pressure is applied to any type of existing rock. Igneous rocks are formed when magma cools. The magma can be made up of melted rocks of any kind (sedimentary, igneous, or metamorphic). The cycle repeats itself all the time and all of the rocks can come from any other kind of rock.
