The rock that is formed from light-colored lave is called rhyolite.
The rock that is formed from light-colored lave is called rhyolite.
Igneous rock is formed from solidified and cooled magma or lava.
Pumice is a light and glassy rock formed from frothy lava that has cooled rapidly, trapping gas bubbles in the process. It is commonly used in abrasives, as a soil amendment, and in cosmetics due to its abrasive and exfoliating properties.
Igneous rocks are formed when lava cools. After a eruption, the lava cools, and the igneous rock is formed.
The rock formed is very light and is known as pumice or pumice stone.
Pumice rock.
When lava cools it forms extrusive igneous rock.
volcanic rocks formed from different processes. Pumice is a light and porous rock formed from foamy lava, obsidian is a dark volcanic glass formed from quickly cooled lava, and scoria is a dark, vesicular rock formed from gas-rich lava.
Intrusive igneous rocks are thusly formed.
Igneous rock is formed.
Igneous rock is formed from lava that has cooled and, of course, hardened.
