When a rock is subjected to pressure greater than 1500 bars and temperatures higher than 150 - 200°C it undergoes a process known as metamorphism which causes a profound chemical and/or physical change to the rock.
What else can I help you with?
What processes found at hot spots will help form the following rocks?
Metamorphic rocks are formed by continental plates colliding. These are Himalayan or Alps mountains. Sedimentary rock is also made into mountains when it is pushed up where tectonic plates collide.
What type of rock means changed form?
Metamorphic rock is a type of rock that has been changed from its original form through heat, pressure, or chemical processes. This transformation often occurs deep within the Earth's crust. Examples of metamorphic rocks include marble, slate, and gneiss.
Does Metamorphic rocks form only from igneous rocks true or false?
False. Metamorphic rocks can form from igneous, sedimentary, or other metamorphic rocks through processes such as heat, pressure, and/or chemical activity. The rock's original composition and mineralogy can change during this process.
Does it take millions of years to form a metamorphic rock?
No, metamorphic rocks form over thousands to millions of years through the intense heat and pressure acting on existing rocks. The exact time it takes depends on the specific conditions present during the metamorphic process.
Why do metamorphic rocks often form deep under the surface of the earth?
Metamorphic rocks form deep under the Earth's surface because the high pressures and temperatures required for the transformation of existing rocks into metamorphic rocks are typically found at greater depths. These conditions are usually created by tectonic forces or by the burial of rocks under layers of sediment.
What processes found at hot spots will form metamorphic rocks?
Metamorphic rocks at hot spots will form mostly by contact and hydrothermal metamorphism as a result of exposure to heat from magma and interaction with hot water respectively.
Where is the energy source found that drives the processes that form igneous and metamorphic?
Mantle convection
What energy source drives the processes that form igneous and metamorphic rocks is found in?
earth's interior
What do metamorphic rocks form from?
nonliving processes of heating and pressurization.
Is black tourmaline metamorphic?
Black tourmaline, also known as schorl, is not classified as a metamorphic rock itself; rather, it is a mineral that can form in various geological environments, including igneous and metamorphic settings. It is commonly found in granite and other crystalline rocks and can also occur in metamorphic rocks where it may form from the alteration of other minerals. While the mineral can be associated with metamorphic processes, it is not exclusively a metamorphic mineral.
Is nickel metamorphic sedimentary or igneous rock?
Nickel itself is not a type of rock; rather, it is a metal that can be found in various geological contexts. Nickel is often associated with igneous rocks, particularly in the form of sulfide deposits, which can form from magmatic processes. It can also be found in some metamorphic rocks, but it is not typically classified as a sedimentary rock. Overall, nickel is primarily linked to igneous processes in the Earth's crust.
Where is energy source that drives the processes that form igneous and metamorphic rocks?
Mantle convection
The relationship among igneous... metamorphic... and sedimentary rocks and the processes that form them are shown by the WHAT?
The rock cycle.
Does brick turn into a metamorphic rock when its melted?
No. Metamorphic rock froms from processes that take place in the solid state. Rocks that form from molten material are igneous.
What process found at a divergent boundary will help form a metamorphic?
The process that is found at a divergent boundary that will help form metamorphic rocks is metamorphism. This refers to the change in the composition or structure of a rock by heat and pressure.
What processes found at hot spots will help form the following rocks?
Metamorphic rocks are formed by continental plates colliding. These are Himalayan or Alps mountains. Sedimentary rock is also made into mountains when it is pushed up where tectonic plates collide.
Where is energy source found that drives the processes that form igneous and metamorphic rocks?
The energy source that drives the processes forming igneous and metamorphic rocks is primarily found within the Earth's interior. It originates from heat generated by radioactive decay in the mantle and core, which drives convection currents that bring hot molten material to the surface and causes interactions that lead to rock formation.
