What is the liquid found in volcanic rocks called?
Geothermal Water
Why are extrusive rocks sometimes referred to as volcanic?
An extrusive rock is a rock that has been deposited at the earths surface as a liquid/fluid, coming to the surface form a depth through a fissure in the earth as a liquid/fluid. The most common type of liquid rock is a magma and magmas erupting at the surface are called "volcanoes" and thus the rocks are called "volcanic" rocks. However there are also volcanoes to be found that have nothing to do with molten rock magmas. These are called "Mud" volcanoes and they are caused by de-watering processes in rocks. The muds brought to the surface are also technically extrusive and these are NOT volcanic rocks.
What are the key differences between volcanic and plutonic rocks in terms of their formation and characteristics?
Volcanic rocks form from lava that cools quickly on the Earth's surface, while plutonic rocks form from magma that cools slowly beneath the surface. Volcanic rocks have fine-grained textures, while plutonic rocks have coarse-grained textures. Volcanic rocks are often found in volcanic regions, while plutonic rocks are typically found deeper underground.
Do volcanic rocks have oxygen?
Yes, volcanic rocks consist of minerals that contain oxygen as an essential component. Oxygen is typically bonded with other elements like silicon, aluminum, or other cations to form the minerals found in volcanic rocks.
Where are granite rocks normally found?
normally found in a volcanic eruption zone where carbon is present
What rocks are found near krakatau?
The rocks found near Krakatau are primarily volcanic in origin, such as basalt, andesite, and dacite. These rocks were formed during the explosive eruption of Krakatau in 1883 and subsequent volcanic activity in the region. Additionally, pumice rocks, a type of volcanic glass, can also be found in the area due to the explosive nature of the eruption.
Are volcanic rocks igneous rocks?
Yes. Volcanic rocks are extrusive igneous rocks.
Where is pigeonite normally found?
Pigeonite is normally found in igneous rocks such as dacite and andesite which are both extrusive igneous rocks. Pigeonite is found in meteorites such as eucrite and achondrite. In volcanic rocks it is found as phenocrysts and as crystals in meteorites.
Is usually found near a volcano?
Igneous rocks and volcanic minerals are usually found near a volcano.
Are igneous rocks found near volcanoic?
Yes, igneous rocks are commonly found near volcanic areas because they are formed from the solidification of molten magma. Volcanic eruptions bring magma to the surface, where it cools and solidifies to create igneous rocks like basalt and rhyolite.
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.
What voltaian rocks?
Volcanic rocks are rocks that form from the solidification of molten lava and can be found near or on volcanoes. They are typically fine-grained due to rapid cooling and can contain minerals such as basalt, andesite, and rhyolite. Volcanic rocks are common in areas with tectonic activity and can provide important clues about the history of volcanic eruptions.
