The common usage of "lava rock" in the USA refers to a black rock with a number of visible bubbles or air pockets that is formed from cooled lava on the surface. Although lava rock is an igneous rock, it is not the same as the definition for the word igneous, which can also include igneous rocks which have solidified from magma below the surface.
What else can I help you with?
When lava cools does it become sedimentary rock?
No. It becomes igneous rock.
Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
Is sandstone an igneous rock?
No. Sandstone is a sedimentary rock, composed of cemented grains of sand-sized sediment particles. Igneous rock is formed from the cooling of magma or lava.
What process must a sedimentary rock go through to form igneous rock?
To form igneous rock from sedimentary rock, the sedimentary rock must first undergo metamorphism, where it is subjected to high heat and pressure, changing its mineral composition. Subsequently, if it melts completely, it transforms into magma. When this magma cools and solidifies, either below the Earth's surface (intrusive igneous rock) or after erupting as lava (extrusive igneous rock), it becomes igneous rock.
Is it possible that the igneous rock can be formed into sedimentary or metamorphic or sedimentary to igneous or metamorphic?
Most of it you got right. Have you ever heard of something called the rock cycle? If you have, good. If you haven't, here is a link to an excellent diagram: http://www.emporia.edu/earthsci/student/henderson1/rock_cycle.gif Anyway, if you look at the diagram, you can see how igneous rock can transform into sediment, then sedimentary rock, or bypass sedimentary rock altogether and go to metamorphic rock. Sedimentary rock can turn into metamorphic rock with heat and pressure. However, to turn into igneous rock from sedimentary rock, it will have to melt down into magma/lava before becoming igneous rock once again.
When lava cools does it become sedimentary rock?
No. It becomes igneous rock.
Is lava a sedimentary rock?
No, lava is not a sedimentary rock. Lava is molten rock that erupts onto Earth's surface from a volcano, and when it cools and solidifies, it forms an igneous rock called basalt or rhyolite. Sedimentary rocks are formed through the accumulation and consolidation of sediments, not from volcanic activity.
Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
What is the difference between igneous and sedimentary rocks?
Igneous rock is formed from the solidification of magma or lava. Sedimentary rock is formed from the lithification of sediments, generally.
Is basalt igneous sedimentary metamorphic?
Basalt is an igneous rock . . . it is pretty much hardened lava.
How would igneous rock be on a layer of sedimentary rock?
The igneous rock could have been erupted as lava on the surface, or intruded into the sedimentary rock layers as magma underneath the surface (a sill).
Is sandstone an igneous rock?
No. Sandstone is a sedimentary rock, composed of cemented grains of sand-sized sediment particles. Igneous rock is formed from the cooling of magma or lava.
What ia an igneous rock?
An igneous rock is the only type of rock out of the 3 (igneous,sedimentary and metamorphic) in which it is formed out of pure lava. So, when a volcano spews lava (or magma), it cools and hardens, becoming igneous rock (pretty simple process).
Is obsidian rock metamorphic rock sedimentary or igneous?
Obsidian is an extrusive igneous rock, formed from rapidly cooling lava.
Does sedimentary rock form when lava cools quickly?
No igneous rock does. A hint for remembering that is igneous sounds like ignite which means to burn.
How can a metamorphic rock turn into sedimentary rock and then back to metamorphic?
metamorphic rock melts turns into lava,lava cools turns into igneous rock,igneous rock is weathered and eroded into sediment,sediment turns into sedimentary rocksedimentary rock gets heated and squeezed forms metamorphic rockcycle continues.......
Is granite is a igneous sedimentary or metamorphic?
the granite melts into lava then cools becoming igneous. it erodes into sediment and then gets compressed into a sedimentary rock. the sedimentary rock becomes metamorphic with heat and pressure deep within Earth
