Is dacite a metamorphic rock?
No. Dacite is an extrusive igneous rock.
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.
Would you expect a course grained extrusive rock like dacite to form?
Dacite is typically an intermediate volcanic rock that forms from the rapid cooling of lava at or near the Earth's surface, resulting in a fine-grained texture. However, if it were to form as a coarse-grained rock, it would likely require a longer cooling period, suggesting a more intrusive environment, such as a shallow magma chamber. In its typical extrusive form, dacite does not exhibit coarse grain; thus, it is unlikely for coarse-grained dacite to form under standard conditions of rapid lava cooling.
Is marble an extrusive or an intrusive rock?
Neither. The terms intrusive and extrusive apply to igneous rocks; marble is metamorphic.

What is the difference between tonalite and dacite?
Dacite is an extrusive rock while tontalite (along with granodiorite) is an iuntrusive equivalent. While dacite forms on the surface as the result of a volcanic eruption, tontalite forms when magma of a similar composition solidifies underground.
Is basalt an intrusive rock or extrusive rock?
Extrusive. Solidifies above ground level.
What are the main two types of igneous rocks?
Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.
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.
Does lava produce Extrusive or Intrusive rocks?
extrusive
Is a metamorphic rock intrusive or extrusive?
