Magma that reaches the Earth's surface is called what?
Magma that reaches the surface is referred to as lava.magma that has reached the earth's surface tends to cool faster, that is why the rock will have more holes in it than a rock that has not reached the earth's surface. magma that has cooled enough to become a rock is known as a igneous rock. but there are two types of igneous rock. ther is intrusive igneous and extrusive igneous. intrusive is when the magma has cooled on the inside. this rock will have large crystals because it has cooled slower and most likely it will have a fine grained texture. extrusive igneous is when magma has reached earths surface (thats when it becomes lava) and has cooled. these rock with either have very small microscopic crystals or no crystals at all because the lava cools so quickly that they do not have enough time to really form.
How is it possible to have more than one type of igneous rock form from a particular magma?
If a portion of the magma stays undergound and cools, it will become an intrusive igneous rock, with a fairly large crystalline structure. If the remaining portion of the magma reaches the surface, it will cool quickly, with a small crystalline structure and become an extrusive igneous rock. The chemical composition of the two rocks, however, will be identical.
When igneous rocks are exposed on Earth's surface and undergo weathering they eventually become which rock?
When igneous rocks are exposed on Earth's surface and undergo weathering, they break down into smaller particles and eventually become sedimentary rocks through the process of erosion, transportation, deposition, and lithification.
What are rocks changed by intense pressure and heat become new rocks called?
Rocks changed by intense pressure and heat become new rocks called metamorphic rocks. These rocks form when existing rocks undergo changes in texture and mineral composition due to high temperatures and pressures. Examples of metamorphic rocks include marble, slate, and gneiss.
What are xenoliths?
Xenoliths are pieces of rock that become incorporated into a larger rock during its formation. They are typically of a different composition and origin than the surrounding rock, providing clues about the processes happening beneath the Earth's surface. Xenoliths are often brought to the surface through volcanic eruptions.
How does batholiths become visible on the earths surface?
Batholiths become visible on the Earth's surface primarily through the processes of erosion and uplift. Over time, the overlying rock layers are removed by weathering and erosion, exposing the large mass of intrusive igneous rock. Additionally, tectonic activities can uplift these formations, making them more accessible. As a result, what was once buried deep underground can eventually become prominent features in the landscape.
What must happen to rock before it become an igneous rock?
Before a rock can become an igneous rock, it must undergo melting to transform from solid rock into molten magma or lava. Once this molten material cools and solidifies, either beneath the Earth's surface (forming intrusive igneous rocks) or on the surface following a volcanic eruption (forming extrusive igneous rocks), it becomes igneous rock.
Does a igneous rock forms from lava?
Yes, an igneous rock forms when lava is cooled. It is called an extrusive igneous rock (because lava is extruded onto the surface of the earth). A magma pool that did not erupt as lava can cool to become an intrusive rock.
How do volcanopes make igneous rocks?
They extrude to the surface of the Earth and and as they solidify they become harder and form a ignous rock. Some form below and some form above surface. The basalt are the surface one and the Granites are the intrusive ones.
Does an intrusive igneous rock sometimes become a sedimentary rock?
Yes, an intrusive igneous rock can sometimes become a sedimentary rock through the process of weathering and erosion. As the rock is exposed at the Earth's surface, it can break down into sediments that will eventually undergo compaction and cementation to form a sedimentary rock.

What type of rock can become magma?
Cooled and solidified magma that rests below the surface becomes intrusive igneous rock. When magma is erupted onto the surface, then cools and solidifies, it becomes extrusive igneous rock. The major rock classification for cooled magma or lava would be IGNEOUS.

What must happen before a rock can become an igneous rock?
Before a rock can become an igneous rock, it must undergo melting to form magma. This typically occurs when rocks are subjected to high temperatures and pressures, often in subduction zones or at mid-ocean ridges. Once the magma rises to the surface or cools underground, it solidifies to form igneous rock. The cooling process can happen rapidly, resulting in extrusive igneous rocks, or slowly, producing intrusive igneous rocks.
Is weathered intrusive or extrusive?
Neither, at the surface all rocks become weathered.
Can intrusive igneous rock becomes a sedimentary rock?
Yes and No An igneous rock can not just "become" a sedimentary rock, it first has to be weathered and eroded at the surface of the Earth. The debris produced is then washed away as sediment and deposited elsewhere. This deposited sediment then gradually hardens into a new rock which is a sedimentary rock. Thus until igneous rocks are exposed in outcrop, they remain as igneous rocks.
What is the name of igneous rocks that have large crystals and small crystals?
Large Crystals = Intrusive Small Crystals = Extrusive The name relates to where the minerals were cooled (at at what rate). In the case of intrusive igneous, the rocks were formed above Earth's surface and were thus cooled quickly and the minerals had little time to become defined. Extrusive rocks, therefore, were formed within the Earth's mantle and had a much longer time before being gathered to cool (as they slowly rose to the top).
