Rock that is formed from volcanoes are igneous rocks. Sedimentary rocks are formed from other layers of grains that are heaving and over millions of years have enough weight squish the grains into a proper rock. This is why the newest rocks are found at the top of layers.
Igneous rocks are made from solidified lava. Sedimentary rocks are made from cemented or compacted sediments formed when igneous rocks erode.

A rock made from cooled magma or lava?
Igneous rock is formed from solidified and cooled 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.
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.......
Are sedimentary rocks are the only ones that can be solidified?
Rocks are invariably considered as solid, though on a geological scale, they may be plastic. Granites, and volcanic output are rocks, as are metamorphosed rocks such as marble ans schist. Liquid lava is not yet a rock but will be when it chills.
What rocks are formed from molten rock that has solidified?
Igneous rocks, which come in many different forms.
A rock made from cooled magma or lava?
Igneous rock is formed from solidified and cooled magma or lava.
What is igneous rock made of?
Solidified magma or lava.
The solidified lava of a volcano belongs to which rock family?
The solidified lava of a volcano belongs to the igneous rock family. These rocks form from the solidification and crystallization of molten magma.
Is sandstone volcanic?
No, sandstone is not volcanic. Sandstone is a sedimentary rock that is formed from the compacted sand grains, while volcanic rocks are formed from solidified magma or lava that has cooled and solidified.
Is lava a sedimentary rock or igneous?
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 makes an igneous rock?
Solidified magma or lava is igneous rock.
Suppose a lava flow was found between two sedimentary rock layers How could you use the lava flow to learn about the ages of the sedimentary rock layers?
You could use radiometric dating of the lava flow to determine its age, which would provide a maximum age for the sedimentary rock layers below it. By knowing the age of the lava flow and the relative positions of the layers, you can infer the relative ages of the sedimentary rock layers. This principle is known as the law of superposition in geology.
How is sedimentary rock relate to magma and lava?
because half of it is made of frozen or either hardend lava so it is related to lava
What do you call molten rock once it has erupted?
Once molten rock has erupted and solidified, it is called lava.
Why are fossils found mostly in a sedimentary rock?
Because when the lava killed the animals, their remains stayed in the lava and dried to become sedimentary rock.
What is the most common type of solidified lava?
Basalt, the extrusive igneous rock that comprises most of the oceanic crust, is the most common type of solidified lava.
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.
