It depends on the type of lava. The lava most people think of when they hear the word is basaltic lava. This lava cools into a black rock that may either have a ropey or jagged surface. It will often have bubbles near the surface of a flow. Over time, this rock may turn red as iron in it is oxidized.
Other types of lava may form gray, white, or brownish rocks.

Yes. Cooled lava is extrusive igneous rock.
What type of volcano forms from thin layers of cooled lava?
the Philippines volcano's form thin layer of cooled lava but not really cold like freezing
What forms as result of lava that has cooled at the top of a volcano?
A vent
A black rock formed from cooled lava?
Obsidian
What brought about the solidification of volcanic lava?
It simply cooled down. Lava is liquid rock, so when it is exposed it cools and sets, just like melted wax does.
Is metamorphic rock a cooled lava?
No. Cooled lava would be igneous.

Igneous rock is formed from solidified and cooled magma or lava.
What is cooled lava call?
Cooled lava is called a igneous rock once it has completely cooled and hardened. Some people just call it lava rock.
What types of rocks are formed from a quickly cooled lava flow?

How would viscosity of the lava affect the size of the crystals that forms in the rock as it cools?
If the lava has cooled fast, the Cristal's will be smaller. If the lava cooled slowly, the crystals will be big
