Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.

Basaltic magma forms what kind of igneous rock?
Mafic igneous rock. ( due to Ferromagnesian minerals).
Rock that forms from other rock due to heat and pressure beneath earths surface?
what rock forms from other rock due to heat and pressure under earth's surface
Which type of rock change due to heat and pressure?
metamorphic rock (s)
What igneous rock would form from the magma if it did not reach the surface but instead crystallized at great depth?
If magma does not reach the surface and instead crystallizes at great depth, it forms an intrusive igneous rock called granite. Granite is coarse-grained and typically composed of minerals such as quartz, feldspar, and mica. It forms slowly over millions of years beneath the Earth's surface before being exposed through erosion.
How can you tell if a rock cooled fast or slow?
You would examine a fracture surface of the rock. Intrusive igneous rocks that have cooled very slowly underground have visible crystals and are said to have a phaneritic texture. Granite is an example of this type of rock. Extrusive igneous rocks that have cooled quickly from lava above or on the surface generally will have crystals too small to be visible with the naked eye, in a texture that is referred to as aphanitic. Obsidian is an example of this type of rock.
What type of rock forms due to heating and cooling?
igneous rock is formed by heating and cooling.
What type of rock forms due to high pressure?
metamorphic
Which type of rock forms due to the weight of the overlying rocks?
Metamorphic
Which type of rock forms due to the weight of overlying rocks?
Metamorphic
Which type of rock forms due to weight of the overlying rocks?
Metamorphic
What type of rock forms at the boundary of magma and rock?
Contact metamorphic rock forms at such boundaries, as the minerals in the rock change due to the increase in temperature or the influx of heated fluids.
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.
What igneous rock are fine-grained due to fast cooling?
Basalt
What is the name given to the volcanic glass that forms due to very rapid cooling of magma?
Yes obsidian is glassy because it cooled very fast.
What Petroleum forms in permeable rock due to?
Carbonization
What is a rock that forms from other rock due to heat and pressure beneath earths surface?
metamorphic rock
How do fine- grained rock form?
Fine grains usually form due to rapid cooling
