Can granite be metamorphic?
In simplified terms, you can think of gneiss as a metamorphic version of granite. Both gneiss and granite are made of feldspars, quartz, mica, and smaller amounts of dark colored minerals like hornblende. The difference between granite and gneiss is in their overall texture and movement.
What type of rock can turn into a metamorphic rock?
Sedimentary rock
Sedimentary rock can change into metamorphic rock or into igneous rock.
How is igneous rock turned into metamorphic?
Explanation: When massive amounts of heat and pressure are applied to an igneous rock, it compacts and becomes a metamorphic rock.
How are rocks like granite formed?
Igneous rocks are formed from cooling magma deep in Earth’s crust or mantle. This cooling magma crystalizes to form rocks like the granite in your house. A rock that cools within Earth’s crust will cool very slowly and form larger crystals and is called an intrusive igneous rock.
How does granite change into sandstone?
Slowly, water and weather wore away granite through the process of erosion. These granite particles became sand, carried by streams to the ocean. Over millions of years, layers of sandy sediment piled up on the ocean floor. Slowly, the sediments were pressed together and cemented to form sandstone, a sedimentary rock.
How granite is formed?
Granite is formed when viscous (thick/ sticky) magma slowly cools and crystallises long before it is able to reach the Earth’s surface.
Where do most Metamorphic rocks form?
Most metamorphic rocks form deep below the Earth’s surface. These rocks are formed from either igneous or sedimentary rocks, making them a changed…
What processes create metamorphic rocks?
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
How is granite made?
Granite is a naturally occurring rock that is formed deep beneath the Earth’s crust over millions of years when Magma or Lava cools and solidifies under heavy pressures. The granite is called an Igneous Rock derived from a Latin word “Ignis” meaning fire.
How is granite formed what is its use?
Granite is an igneous rock which means it is formed when the magma of the volcano oxidises and then begins to slowly solidify under the ground. When the magma of the volcano forms, silica (in high content) along with the oxides of alkali metals gradually solidify and lead to forming the granite stone.
What sedimentary rock does granite turn into?
gneiss
When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss. Slate is another common metamorphic rock that forms from shale.
What step in the rock cycle would be required to change granite into sandstone?
| QUESTIONS | ANSWERS |

Why is granite considered a metamorphic rock?
Granite is also metamorphic , which means it goes through changes caused by chemical reactions that cause it to rise and find cracks in the crust before the settling and emplacement processes. All igneous rocks are porous, and granite is no exception.
What type of rocks can become metamorphic?
Metamorphic rocks are formed when a preexisting rock, called a protolith, is under conditions of high heat and pressure, causing it to metamorphose chemically, structurally, or both. The protolith might be an igneous, sedimentary, or another metamorphic rock. Slate, marble, and quartzite are some examples of this type.
What produces metamorphic rock?
Metamorphic rock is produced from either igneous rock (rock formed from the cooling and hardening of magma) or sedimentary rock (rock formed from compressed and solidified layers of organic or inorganic matter). Most of Earth’s crust is made up of metamorphic rock.
What are the three types of metamorphic rocks?
There are three ways that metamorphic rocks can form. The three types of metamorphism are Contact, Regional, and Dynamic metamorphism. Contact Metamorphism occurs when magma comes in contact with an already existing body of rock.
