Which countries has volcanic rocks in Caribbean?
Some of the countries in the Caribbean with volcanic rocks include Montserrat, Dominica, St. Kitts and Nevis, Grenada, and St. Lucia. These volcanic islands are part of the Lesser Antilles volcanic arc.
What are volcanic rocks?
Volcanic rocks are classified as extrusive igneous rocks, forming from the solidification of lava.
Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
Where are some of Earth's youngest rocks found?
Some of Earth's youngest rocks are found along mid-ocean ridges, where tectonic plates are moving apart and new oceanic crust is formed through volcanic activity. Young volcanic islands, like Hawaii, also have very young rocks due to ongoing volcanic eruptions. Additionally, areas with recent volcanic activity, such as Iceland, have young rocks as well.

Are volcanic rocks igneous rocks?
Yes. Volcanic rocks are extrusive igneous rocks.
Are Volcanic rocks metal?
No. Volcanic rocks are made of the same materials that other rocks are.
Are metamorphic rocks volcanic?
No. Only extrusive igneous rocks are volcanic.
What are volcanic rocks?
Volcanic rocks are classified as extrusive igneous rocks, forming from the solidification of lava.
Are intrusive rocks volcanic?
No. Volcanic rocks are extrusive. Intrusive rocks are sometimes called plutonic.
What rocks have a pyroclastic texture?
Volcanic rocks such as tuff and ignimbrite typically have a pyroclastic texture. These rocks are formed from the accumulation of volcanic ash, pumice, and other volcanic fragments that are deposited during explosive volcanic eruptions. The fragments are welded together upon cooling to form a solid rock.
Are volcanic rocks hot?
Volcanic rocks are hot if they are freshly erupted. Otherwise, no.
What are some rocks that begin with the letter R?
· Rhyodacite - a volcanic rock
Is volcanic rock older than sedimentary rock?
Not necessarily. There are volcanic rocks that date back to the precambrian time, much older than most sedimentary rocks around today. At the same time, as there is still continuous volcanic activity on earth, some volcanic rocks may be only minutes old, making them the youngest rocks on earth.
Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
Are volcanic rocks sedimentary?
No. Volcanic rocks are igneous (although not all igneous rocks are volcanic). Sedimentary rocks are made of sediment naturally cemented together. However, volcanic (or extrusive igneous) rocks can be eroded into sediment, which can be cemented, compacted, or otherwise become sedimentary rock such as sandstone or conglomerate. It is then not considered igneous.
