Compare and contrast contact metamorphism and regional metamorphism?
Contact metamorphism is the process of forming rocks from the heat of magma intrusion. Regional metamorphism, meanwhile, is the process of forming rocks by pressure and heat at plate boundaries.
Magma that forces its way into rocks and hardens is called a extrusion or fault or unconformity or intrusion?
Magma that forces its way into rocks and hardens is called intrusion.
What process is required for minerals to crystallize to magma?
Minerals in magma crystallize through the process of cooling and solidification. As magma cools, atoms and ions within the molten rock arrange themselves into an ordered, repeating three-dimensional pattern, forming mineral crystals. The specific minerals that crystallize depend on factors such as temperature, pressure, and chemical composition of the magma.
The process that causes liquid rock to move is called?
The process that causes liquid rock to move is called magma migration. This movement occurs due to changes in temperature and pressure within the Earth's crust, which can lead to the rise of molten rock towards the surface, eventually forming volcanoes when it erupts.
How are crystallization and cooling magma related?
Crystallization and cooling magma are related in the sense that cooling and crystallization occurs simultaneously. As the magma cools it crystallizes, the faster the rate of cooling the quicker crystals would develop and the slower the cooling the larger the crystals in other cases when the magma cool so rapidly crystal development may not be so prominent.
What rock-forming process occurs when magma forces its way into rock?
contact metamorphism
What rock forming process occures when hot magma forces its way into rock?
contact metamorphism
Magma reaches the earths surface as a result of the process called?
Magma reaches the Earth's surface through a process called volcanic eruption. This occurs when pressure builds up underground and forces the magma to flow and eventually break through the Earth's surface. Once the magma reaches the surface, it is then called lava.
What Magma and lava can both solidify to produce?
They are both the same thing, which is melted rock, which means they solidify to form rock. The only difference between magma and lava is that magma is underground, and lava is not.
How are hot spots formed?
from being under the mantle the gas pressure builds up and forces magma out forming a hot spot.
Compare and contrast contact metamorphism and regional metamorphism.?
Contact metamorphism is the process of forming rocks from the heat of magma intrusion. Regional metamorphism, meanwhile, is the process of forming rocks by pressure and heat at plate boundaries.
What is the source pf the magma that rises at the boundary between the African plate amd the Arabian plate?
The magma that rises at the boundary between the African plate and the Arabian plate primarily originates from the asthenosphere, where partial melting occurs due to the tectonic activity associated with the rifting of the East African Rift System. As the plates diverge, the reduction in pressure allows mantle rocks to melt, forming magma that can ascend through the lithosphere. This process is also influenced by the presence of hotspots and the interaction of tectonic forces in the region.

Magma that forces its way into rocks and hardens is called a extrusion or fault or unconformity or intrusion?
Magma that forces its way into rocks and hardens is called intrusion.
What rock melts then hardens again?
Metamorphic rocks can melt under high temperatures and pressures, forming magma. When this magma cools and solidifies, it forms igneous rocks. This process is known as migmatization.
Some crystals are formed from hot melted rock called?
magma. When magma cools and solidifies underground, it can lead to the formation of crystals through a process called crystallization. This process allows atoms and molecules to arrange themselves in a repeating pattern, forming the distinct geometric shapes commonly associated with crystals.
What occurs when heat from nearby magma causes changes in the surrounding rocks?
When heat from nearby magma causes changes in surrounding rocks, a process called contact metamorphism occurs. This process includes changes in rock texture and mineral composition due to the high temperature and pressure from the magma. This usually results in the formation of new minerals and textures within the rocks.
