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.

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 lava a metamorphic rock?
no lava is a liquid that when cooled forms extrusive igneous rock Metamorphic rock is something that has been "metamorphosed" usually by being shoved down into the high temperatures and pressures inside the earth by tectonic plate movement. Sandstone (soft) can become granite (hard) in this way.
Is limestone a intrusive igneous rock?
No. Limestone is a sedimentary rock formed when calcium carbonate precipitates from the ocean.
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 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).
What type of rock is formed when lava flowing from a volcano cools and hardens?
Extrusive igneous rock is formed from cooling 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).
How does Sedimentary rocks change to igneous rock?
Sedimentary rock melts, then it cools to form Igneous rock. Hoped this helped. :)
Is lava a metamorphic rock?
no lava is a liquid that when cooled forms extrusive igneous rock Metamorphic rock is something that has been "metamorphosed" usually by being shoved down into the high temperatures and pressures inside the earth by tectonic plate movement. Sandstone (soft) can become granite (hard) in this way.
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.
