Magma hardening beneath the Earth's crust is called 'intrusive' magma (rather than 'eruptive' or 'extrusive' magma). Such magmas, when cooling, form rocks with larger crystals (because they cool slowly) and form rock types such as 'Granite' (acid) or 'Gabbro' (basic). They may also form Layered Igneous Intrusions and batholyths. All of these are types of 'Igneous' rocks (as are lavas).

They DO NOT turn into metamorphic rocks as they cool from the liquid state. However, the rocks into which they are intruded may be thermally metamorphosed by the hot magma.

How is sedimenary rocks formed?

Sedimentary rocks are formed from the earths surface when sediments hardens into rocks :]


What rock is formed when magma cools slowly beneath earths surface?

Intrusive igneous rock.


What groups of rocks can igneous rocks be formed from?

igneous rocks are formed by magma reaching earths surface and cooling quickly to form extrusive igneous rock.another igneous rock is called intrusive igneous rock. it is formed when magma cools and hardens below the surface.


What igneous rock that formed from lava that erupted into earths surface are called?

When igneous rock forms on the Earth's surface, including on the ocean floor, it's called extrusive. It's called intrusive rock when it forms beneath Earth's surface, such as in mines.


Is it true that igneous rocks form only beneath earths surface?

It is not true. Extrusive rock forms on the surface from solidifying lava.


What is formed from the remains of plants an animals that has been stored beneath the earths surface for millions of years?

parhaps fossils, roots, ashes or even new compost


How and where are igneous rocks formed?

Igneous rocks are formed on and below the surface of the Earth when lava or magma cools enough to crystallize.


How do intrusiver rocks form?

intrusive rocks are formed within the earths surface from magma. extrusive rocks are formed from lava outside of earths surface


What processes at a divergent boundary will help form the following rocks?

The process of upwelling magma is found a divergent boundaries. As this magma nears the surface it decompresses, and some of it flows onto the surface of the Earth as lava. Magma that solidifies beneath the surface of the Earth hardens into gabbro while lava on the surface of the Earth hardens into basalt. Both of these are igneous rocks. Metamorphic rocks are formed from the heat flowing from the igneous rocks. Sedimentary rocks are formed from the sediments collecting in the basins created from rifting (that is, the divergent boundaries). Metamorphic and sedimentary rocks are not considered to be formed at divergent boundaries.


How was Mount Taranaki formed?

It was formed by the pacific plate sub ducting beneath the Australian plate. The pacific plate slides into the earths mantle, where it melts. the molten rock then rises to the surface because it is less dense and forms a volcano


What are extrusive and intrusive igneous rock?

Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
