Lava flows cool to form extrusive igneous rock. Most lava flows consist of basaltic lava, cooling to form a dark rock called basalt. Some, however, may consist of andesite or, rarely, rhyolite and similar lavas.
Lava
Indeed it does! Depending on how fast the lava crystalizes a different rock will be formed. Rocks that form from within the earth (like through a volcanic eruption, lava flow, magma intrusion, ect) are known as igneous rocks. Igneous rocks include granite, basalt, obsidian, andesite, among others. Basalt and obsidian are arguably the most well known rocks formed from a lava flow.
no, there are more rocks
the lava flow is a density independent that flow good from the chemicals lava it have to flow and it is independent
Lava that is low in silica tends to have lighter rocks come out of it.
pahoehoe or a'a rocks are the most common coming from a lava flow. pahoehoe or a'a rocks are the most common coming from a lava flow. pahoehoe or a'a rocks are the most common coming from a lava flow.
Cooled lava produces extrusive igneous rock.
Lava
It is called Lava
While searching the lava flow, I found sedimentary rocks.

Usually rhyolite or dacite.
Lava. (When it is underground it is called magma)
. I would expect to find nonfoliated rock next to a lava flow because the rock can form when rock is subjected to high temperatures. Hornfels, which often forms when magma or lava touches other rock, is nonfoliated.
Rocks are grouped by how they are formed. There are 3 types of rocks. Sedimentary, Metamorphic, and Igneous rock. Sedimentary rocks are made from broken down rocks, called sediment, which come from all three rocks. Metamorphic rocks come from existing rocks that are changed by heat and pressure. The Igneous rocks are formed from magma that rose up to the surface, also known as lava. When the lava cools and hardens it forms igneous rocks. That is a rock cycle.

They are made from cooled lava, because they come from volcano's, and the center of the earth, which has magma (lava) flowing around.no
