How do igneous rocks form into metamorphic and sedimentary rocks?
Igneous-sedimentary weathering/erosion Igneous-Metamorphic high pressure and heat
What kind of rock is formed with heat and pressure?
Metamorphic rocks, like slate or quartizite, or even diamonds.
Why is igneous rock called a mother rock?
Igneous rock is a category of rocks a parent rock can be igneous metamorphic or sedimentary
What is a kind of non foliated metamorphic rock?
Metamorphic rocks are rocks that have their grains arranged in parallel layers or bands. Foliated rocks are formed under great pressure and heat, and when they cool they have a banded grain pattern.
Rock formed by heat and pressure?
Metamorphic Rock
Slate and marble are examples of what kind of rock family?
Slate and Marble are metamorphic rocks. Slate's parent rock is shale and Marble's parent rock is limestone.
How do igneous rocks form into metamorphic and sedimentary rocks?
Igneous-sedimentary weathering/erosion Igneous-Metamorphic high pressure and heat
Is marble metamorphic rock?
Yes. Metamorphic rock can be marble because, marble is a form of Metamorphic rock which is composed of coarse crystals from parent limestone or dolostone rocks.
How is a metamorphic rock formed'?
Non-foliated metamorphic rocks such as quartzite and marble do not display the banding or layering that are present in foliated rocks. This is because their parent rock was usually sedimentary and more pure in mineral composition than the parent rocks of foliated rocks. The metamorphic rock forms from conditions of high heat and/or pressure from depth of burial.
Rocks that differ greatly from their parent rock have what characteristic?
A high metamorphic grade
Can metamorphic rocks from from other metamorphic rocks?
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
What are the parent rocks of the metamorphic rock?
1. Marble ----- Limestone or dolostone 2. Gneiss ----- Granite or schist 3. Quartzite --- Sandstone 4. Schist ----- phyllite
Is metamorphic rocks made up of sedimentary rock igneous rock or other metamorphic rocks?
Metamorphic rocks
Why are metamorphic rocks different from igneous and sedimentary rocks?
The metamorphic processes of heat and pressure can alter the parent rock (sedimentary, igneous, metamorphic) chemically or structurally into a form of rock that can only be created under certain conditions. Metamorphic rocks are not created from sedimentation and lithification or from molten material.
What rocks change into metamorphic rocks?
Any type of rock can become metamorphic.
What are parent rock?
The parent rock (protolith) is the rock type that existed before a rock is altered into metamorphic rock. For instance, shale (sedimentary rock) is the parent rock of slate (metamorphic rock).
Do sedimentary rocks have parent rocks?
In a sense they do, but not in the geologic sense that a metamorphic rock does. Most sedimentary rocks are formed from particles of other rocks which could be a mixture of all three types (sedimentary, igneous, metamorphic). Therefore they would have multiple parents, so the term "parent rock" is not used. The term most used is "source rock'.
