Aquifers are rock layers that are what?
Aquifer are underground areas of saturated permeable rock or sediments above layers of impermeable rock that have the ability to hold/retain ground water, preventing it from percolation and infiltration, thereby serving as a form of natural water storage .
What is formed when rocks melt underground?
sedimentery rock
What is the only kind of rock that can form directly from magma?
By definition. A sedimentary rock is formed from sediments, chemical, organic, or clastic. A metamorphic rock has undergone a change in mineral alignment or mineral composition due to heat and/or pressure. An igneous rock forms from solidification of magma via cooling.
Is travertine metamophic rock?
Travertine is a type of metamorphic rock. It is also a sedimentary rock, which is usually found near underground water sources.
What observation about an igneous rock would support the inference that the rock cooled slowly underground?
The rock would have visible mineral crystals--a phaneritic texture.
What type of rock can form deep underground?
Metamorphic
What type of rock can only form deep underground?
Metamorphic rock can form deep underground under high pressure and temperature conditions. This type of rock is typically found in the lower parts of Earth's crust and upper mantle where intense heat and pressure can change the structure of existing rocks.
What type of rock can only form deeply underground?
Only an intrusive igneous rock forms underground, but you can argue that all metamorphism occurs underground. The issue here is that when the metamorphism is thermal, often the ground it is under has only just been formed (i.e. a lava flow). To avoid confusion, only regional metamorphism can take place underground. The rocks formed by regional metamorphism and intrusive magma cooling are rocks with crystalline texture.
Where do intrusive igneous rock form?
They form underground from the cooling and solidification of magma.
Does magma form when rock begins to melt?
Yes. Magma is underground molten rock.
How do veins form?
pure metals that crystallize from hot water solutions underground often form veins.Veins form when rock collides with another rock and the rock that collide pushes the other rock untill only a little bit of it is left
What type of rock can only be formed deep underground?
metamorphic
What is the definition of lava?
Molten rock from underground that has risen to the surface. If it is only underground and has not went up, it is called magma.
Granite is an example It forms deep underground It needs heat to form What is it?
Granite is an igneous rock that forms deep underground from the cooling of molten magma. It requires heat and pressure to form, typically found in the Earth's crust.
What are rocks that form when magma cools underground?
Intrusive igneous rocks, such as granite and diorite, form when magma cools underground. These rocks have a coarse-grained texture due to the slow cooling process, allowing large mineral crystals to form within the rock. Intrusive rocks are typically found in plutons or batholiths beneath the Earth's surface.
How does a metamorphic rock form from an igneous rock?
It gets under a lot of pressure underground and then changes. Metamorphic just means changing.
Which groundbreaking rock band did Lou Reed form with John Cale in 1965?
The Velvet Underground
