What two things are necessary for foliation to form in a metamorphic rock?
Directional pressure and differential stress are necessary for foliation to form in a metamorphic rock. Directional pressure causes minerals to align in the direction of the applied pressure, while differential stress leads to the segregation and elongation of mineral grains, resulting in the development of a foliated texture.
Is metamorphic rock rough or smooth?
Metamorphic rock can vary in texture, with some being rough due to the presence of mineral grains and others being smooth due to recrystallization of minerals during the metamorphic process. The texture of metamorphic rock depends on factors such as the original rock type and the intensity of heat and pressure.
What conditions change igneous rocks and sedimentary rocks into metamorphic rocks?
Heat and pressure are the main agents that change igneous and sedimentary rocks into metamorphic rocks. The intense heat and pressure alter the mineral composition and texture of the rocks, resulting in the formation of new minerals and a more compact, crystalline structure. Additionally, the presence of fluids such as water can enhance these metamorphic processes by facilitating mineral reactions.
What causes sedimentary rocks to become metamorphic rocks?
Sedimentary rock can become metamorphic rock under intense heat and pressure. The heat and pressure do not change the rock's chemical composition, but do change its physical properties like hardness, texture, and structure.
What do Metamorphic rocks result from?
Metamorphic rocks result from the alteration of existing rocks due to high temperature, pressure, and/or the presence of chemically active fluids. This process typically occurs deep within the Earth's crust where rocks are subjected to intense heat and pressure, causing them to recrystallize and reorganize into new forms.
What Rocks created by changes in temperature and pressure or the presence of hot watery liquid?
Metamorphic rock.
Rocks created by changes in temperature and pressure or the presence of hot watery liquid?
Metamorphic rock
What Sedimentary rocks is converted into metamorphic rock with the addition of?
Sedimentary rock is converted into metamorphic rock with exposure to heat, pressure, heated mineral solutions, or a combination of any of them.
How does pressure help make metamorphic rocks?
pressure helps the metamorphic with the high temprature or pressure
What is rock that is changed by heat pressure or chemical change?
Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.
How do heat and pressure change sedimentary rock?
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
What two things are necessary for foliation to form in a metamorphic rock?

The texture of metamorphic rock depends on factors such as the original rock type and the intensity of heat and pressure.
How can a rock be transformed into a metamorphic rock?
Rock can be changed into metamorphic rock by heat and pressure.
Is metamorphic rock the rock of heat and pressure?
The rock that gets heat+pressure to turn into a metamorphic rock.
What type of rock forms when heat and pressure change one type of rock into another?
Changes in the structure, texture, or mineralogy of existing rocks will create a metamorphic rock. Metamorphism can result from the effects of heat and/or pressure, or from the addition of ions from heated fluids. Examples of metamorphic rock are slate, schist, and gneiss.
What conditions determine whether metamorphic changes willl occur over a large or small area?
Change over large areas - usually the deeper down rocks are the more change occurs.Usually due to both heat and pressure.Mountain Ranges are example of large area metamorphic. Change over small areas - formed by heat pressure ALONE
