Is magma extrusive or intrusive?
Magma can be either extrusive or intrusive. Extrusive magma forms on the Earth's surface during volcanic eruptions, while intrusive magma forms below the surface and cools slowly to create intrusive igneous rocks.
During the rock cycle what forms when magma cools?
When magma cools you get intrusive igneous rock. Think of other ig words you know. Ignite, ignition they all mean heat. Igneous rocks are formed from rocks that have been heated so much they melt. When they cool they make new, igneous, rocks. If it's magma that cools that means it's still under the earth's crust so the igneous rock is intrusive. If it's lava that cools after flowing down a volcano it's an extrusive igneous rock that's formed.
What happens to lava that does not erupt and stays under the surface?
Lava that does not erupt and stays under the surface will slowly cool and solidify, forming intrusive igneous rocks such as granite or diorite. These rocks may later be exposed at the Earth's surface through erosion or uplift.
What is a hot lava cooling and hardening?
when the hot lava cools deep inside the earth, it is called intrusive igneous rocks. when the hot lava cools on the surface of the earth, it is called extrusive igneous rocks.
Is volcanic rock only igneous?
Lava is, by preferred definition, a viscous fluid comprised of molten rock that has reached the surface. In this case, lava is not an igneous rock. However, 'lava' can also refer to the cooled and solidified product of the molten rock. In this case, lava is an igneous rock, formed from the solidification of molten lava.
What happenes during each method to form intrusive igneous rocks?
Igneous rocks are formed under high heat conditions. Intrusive igneous rocks are formed by the crystallization of magma in the Earth's crust.
Is magma extrusive or intrusive?
Magma can be either extrusive or intrusive. Extrusive magma forms on the Earth's surface during volcanic eruptions, while intrusive magma forms below the surface and cools slowly to create intrusive igneous rocks.
Is feldspar metamorphic igneous or sedimentary?
Feldspar is primarily an igneous rock-forming mineral, commonly found in intrusive and extrusive igneous rocks such as granite and basalt. However, feldspar can also be present in some metamorphic rocks as a result of the recrystallization of pre-existing feldspar minerals during metamorphic processes.
Igneous rocks with a two-stage intrusive-extrusive origin are recognized by a texture which is?
Recognized by a porphyritic texture, where large crystals (phenocrysts) are embedded in a fine-grained matrix. This indicates that the rock underwent two stages of cooling, with the phenocrysts forming during the slow cooling in the intrusive stage, followed by rapid cooling during the extrusive stage to form the fine-grained matrix.
The cooling and hardening of magma deep underground results in what?
The cooling and hardening of magma deep underground results in igneous rock. Rare gems and diamonds can be found in igneous rock.

Which igneous rock can be intrusive and extrusive?
A porphyritic igneous rock demonstrates some extrusive characteristics and some intrusive characteristics. The appearance of phenocrysts (larger crystals) in a fine matrix (small crystals) indicates that the magma had time to cool slowly enough underground to form larger crystals before being erupted at or near the surface.
What happens to lava that does not erupt and stays under the surface?
Lava that does not erupt and stays under the surface will slowly cool and solidify, forming intrusive igneous rocks such as granite or diorite. These rocks may later be exposed at the Earth's surface through erosion or uplift.
Why do some igneous rocks have bubbles or pores and are these rocks intrusive or extrusive?
The bubbles and pores are from trapped gasses which expanded in the molten material as it neared the surface. They're usually found in extrusive igneous rocks, those that have solidified in the air or on the surface.
What is a hot lava cooling and hardening?
when the hot lava cools deep inside the earth, it is called intrusive igneous rocks. when the hot lava cools on the surface of the earth, it is called extrusive igneous rocks.

When igneous rock forms what does magma and lava do?
Magma is molten rock beneath the Earth's surface, while lava is molten rock that flows onto the surface during a volcanic eruption. When magma cools and solidifies underground, it forms intrusive igneous rocks, such as granite. When lava cools and solidifies on the surface, it forms extrusive igneous rocks, such as basalt.
