How do sedimentary rocks becomes igneous?
Sedimentary rocks, as a rule, must first undergo a change into a metamorphic rock (a process which can take hundred of thousands to millions of years), before they may become molten from subduction processes or contact with a body of magma, whereby the magma would cool and form an igneous rock.
What are rocks that form when magma cools underground?
Intrusive igneous rocks, such as granite and diorite, form when magma cools underground. These rocks have a coarse-grained texture due to the slow cooling process, allowing large mineral crystals to form within the rock. Intrusive rocks are typically found in plutons or batholiths beneath the Earth's surface.
How does an intruding magma body make room for itself during emplacement?
An intruding magma body makes room for itself during emplacement by causing the surrounding rocks to deform and fracture. This process occurs through processes such as dilation, where the pressure of the magma forces the surrounding material to expand, and brittle failure, where the rocks break apart to accommodate the incoming magma. As the magma rises, it can also create a network of cracks and fissures, allowing it to move upwards more easily. Ultimately, this creates a space for the magma to occupy as it solidifies into igneous rock.
Can a single magma can produce several different igneous rocks having different mineral compositions?
Yes; through the process know as fractional crystallization, which changes the composition of the magma, therefore changing the minerals that eventually crystallize from it. Fractional crystallization occurs largely from the varying temperatures at which minerals crystallize.
How can you get different igneous rocks from the same magma body?
Magma underground may differentiate and form different intrusive igneous rock. Magma from the magma body may erupt, cool, quickly, and form fine-grained extrusive igneous rock, or partially remain underground and form intrusive igneous rock. The type of igneous rock formed from the magma body will largely depend on whether or not it is erupted, and the speed of its cooling.
Is magma the source of all rocks on earth?
No, while all rocks on Earth were molten at one point, most rock types do not form from magma. Rocks that form from magma or lava are igneous rocks. Most of the rocks at Earth's surface are sedimentary. These rocks form from the remains of rock that have been broken own into tiny pieces or dissolved in water. These components eventually settle, usually in a body of water, and are buried and turned to stone. Metamorphic rocks make up a third category. These form from rocks that have been altered under enormous heat and pressure while remaining solid.
Process that changes rocks which are next to a body of a magma?
because of the gravity of the earth that follows the sun and the moon that occupies space that has mass so that we can measure the world :) sana magustuhan niyo kahit ndi kagandahan ang sagot pero sana maapreciate niyo pinag hirapan ko yan :( mag aral nalang kaung mabuti para kayo naman ang next na magsasagot tnx :*
How is volcano eruption occur?
There are hot gases mixed with magma. Sometimes the pressure of the magma and hot gases increased a great deal when this happens the rocks deep inside the earth have melted on molten rocks which is called magma. This is how a magma occurs.
What is a volcanic dike?
A dike is an intrusive body of volcanic magma that pushes it's way between layers of rocks and sediment.
What term describes the zone of contact metamorphism surrounding an intrusive magma body?
The term that describes the zone of contact metamorphism surrounding an intrusive magma body is "contact aureole." This zone is characterized by the alteration of surrounding rocks due to the heat and fluids released by the intruding magma as it cools and solidifies.
What is formed when a magma chamber cools slowly and hardens underground?
When a magma chamber cools slowly and hardens underground, it forms an intrusive igneous rock body like a pluton or a batholith. These rocks are characterized by large crystals due to the slow cooling process. Examples include granite, diorite, and gabbro.
Where is the dynamic metamorphism located?
Contact metamorphism is defined as metamorphism in which the mineralogy and texture of a body of rock are changed by exposure to the pressure and extreme temperature associated with a body of intruding magma. It can either happen deep underground or at the Earth's surface.
