What rocks forms when magm cools within th earth?
If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
What is the change of state when magma crystallizes to form ingeous rock?
It is according to what kind of material the lava is made from. If there are different minerals in the lava, then it is according to what temperature the mineral returns to the solid state, or a rock. Some minerals have a liquid temperature, close to the liquid temperature of another minerals, and chances are they will form in the same rock. Temperature determines what the rocks will become. Like gold is found in quartz. Their liquid temperatures are close so they form together.
How are igneous rocks with crystals formed?
In magma, the crystals have generally not had a chance to crystallize, although some may already have and some may not have. There are different types of magma, and these lead to the formation of different rocks, depending on the chemical makeup. Common igneous rocks formed from the cooling of magma may contain quartz, feldspars, micas, and amphiboles.
Does igneous rock form from magma?
Magma (molten rock) rises from feeders or volcanic necks beneath the surface of the crust and flows from volcanic openings onto the surface. When magma reaches the surface, it is called lava.When lava reaches the surface, it immediately begins to cool. During this cooling phase, the liquid lava solidifies much as liquid water would freeze if cooled sufficiently. The solidification occurs because of the crystallization of minerals from chemical components (iron, magnesium, silicon, oxygen) in the lava. The lava will transition from a liquid to either a form of natural glass, or to a rock, depending on the speed at which it cools. Obsidian, a natural glass, and basalt, an extrusive igneous rock, are both formed from cooling lava.
How do the magma chambers form?
Magma chambers form when molten rock, or magma, accumulates in underground reservoirs beneath the Earth's surface. This accumulation occurs as magma rises from the mantle due to pressure and temperature differences, often generated by tectonic processes such as subduction or rifting. Over time, as magma collects and cools, it may crystallize into igneous rock, but some remains in a liquid state, creating a chamber that can feed volcanic eruptions. Additionally, the presence of fractures and porous rock can facilitate the movement and storage of magma within these chambers.
How are minerals formed from magma and lava?
Minerals are formed from magma and lava through the process of crystallization. As magma or lava cools, the atoms and ions within the molten rock come together to form solid mineral crystals. The specific minerals that form depend on the composition of the magma or lava and the cooling rate.
Minerals that form from magma are formed by?
Several minerals form in slow cooling magma. Some of those minerals are quartz, plagioclase feldspar, and potassium feldspar. These are the same minerals that are found in granite.

Describe how the cooling rate of magma affects the texture of igneous rock.?
The faster the rate of cooling the smoother the rock will be. The slower the rate the more rough the texture. The faster it cools the finer the texture of the rock. Slower cooling magmas tend to form courser grained igneous rocks. The more time a magma has too cool, the larger the crystals will be If all the minerals in the magma cools at about the same rate you will have roughly equal sized grains in the rock, in which case the rock will be of phaneritic texture. However you will have conditions in which some of the minerals will solidify while other minerals remain liquid, meaning those that have more time to solidify will have larger crystals . The minerals that solidify will have more time to grow as crystals while the other minerals in that magma will have less time and space to grow as crystals meaning those minerals will have smaller crystals. These rocks with crystals of various sizes are called porphoritic rocks (or porphory)

How are intrusive rocks formed?
They are formed from the solidification of magma below the ground.
How does magma turn into?
Magma is essentially molten rock inside earth, possibly with some trapped gasses. To become rock the magma simply cools and solidifies, essentially freezing.

Do minerals form when a hot water solution cools and the minerals crystallize?
A hydrothermal solution is a very hot mixture of water and dissolved substances. Hydrothermal solutions have temperatures between 1000C and 3000C. When these solutions come into contact with existing materials, chemical reactions occur to form new materials. Also, when such solutions cool, some of the elements in them combine to form such minerals as quarts and pyrite.
What effects does temperature have on the characteristics of magma?
The temperature of the magma will affect its viscosity depending on its chemistry. Some minerals crystallize at higher temperatures than others, meaning that portions of the magma may have already solidified. At lower temperatures, the majority of the constituent minerals will have crystallized and solidified, leaving the magma highly viscous.
