What forces could cause a metamorphic rock to become magma?

(For 40 extra points, name how this force can occur inside earth)

What step in the rock cycle creates the sediment from which sedimentary rock is formed?

In the rock cycle, what happens to magma and lava once they cool and harden?

Must sedimentary rock become metamorphic rock before it can become magma?

For a 40 point bonus:  Explain your answer

Describe two pathways through the rock cycle in which igneous rock can become metamorphic rock.

Igneous rock that cools very quickly when it forms may have a texture that is:

A smooth and shiny with no visible grain

or

B. Course grained

Rocks that forms from the cooling of magma below the surface or lava at the surface is called...

Igneous rock that formed from lava that erupted onto Earth's surface is called...

Generally a rock is made up of:

A. Only inorganic materials

B. a mixture of minerals and other materials

C. small crystals

Does Lave form an intrusive or extrusive rock?

Erosion on a mountain range that was pushed up as a result of two continental plates colliding will lead to the formation of....

The  process in which dissolved minerals crystallize and GLUE particles of sediment together is...

How can a fossil of a fish be found in a sedimentary rock?

What kind of rock is made from coral?

Describe a pathway through the ro cycle in which magma becomes sedimentary rock

Where does metamorphic rock form?

Heat and Pressure deep beneath Earth's sruface can change any rock into....

The heat that changes a rock into metamorphic rock comes from:

A. the Sun

B. Volcanoes

C. heat of the mantle

The texture of a metamorphic rock that has grains arranged inparallel layers is described as...

What would happen if the mantle of the Earth cooled?

What forms the structure called a coral reef?

A series of processes on Earth's surface and in the crust and mantle that slowly changes rocks from one kind to another is called...

Which of the following is NOT one of the possible stages in the rock cycle?

A. volcanic activity

B. Erosion

C. Smelting

D. Melting

Why can we find limestone in the middle of the United States?

Why doesn't metamorphic rock rarely forms at Earth's surface?

MELTING

Bonus 40 points:  It is caused by plate tectonics or the crashing of plates

Erosion

Forms Igneous Rock

No

Bonus: Sedimentary rock can melt and turn to magma

1.  Erosion -  Sedimentary Rock - Heat and Pressure - metamorphic rock

2.  Heat and Pressure

A. smooth and shiny with no visible grain

Igneous Rock

extrusive rock

B.  Mixtureof minerals and other materials

extrusive

Sedimentary Rock

cementation

Fish dies and is buried by sediment on the bottom of a river or lake.  

Limestone

Magma cools becomes Igneous Rock,then Erosion, then Sedimentary Rock

deep underground

metamorphic rocks

C.  The heat of the mantle

foliated

No more heat to make metamorphic rocks and no more magma to create Igneous rocks.

Skeletons of coral animals

the Rock Cycle

C. Smelting

Limestone is formed in shallow warm ocean water.  One time due to continental drift the United States was covered with ocean water and near the equator.

You need the heat from the mantle and pressure from plate tectonics deep underground.
