When molten rock or lava cools on the Earth's surface, it solidifies and forms igneous rock. The texture and composition of the rock will depend on the rate at which it cools. Slow cooling often results in larger crystals, while rapid cooling forms smaller crystals or glass. Over time, these rocks can be weathered and eroded, eventually becoming part of the rock cycle.

When molten rock cools or hardens on or earth surface it forms?
Igneous
What forms when molten material from beneath Earth's surface cools and hardens?
When molten material from beneath Earth's surface cools and hardens, it forms igneous rocks. Igneous rocks can be either intrusive (formed underground) or extrusive (formed on the surface), depending on where the cooling and hardening process occurs.
What kind of rock forms when hot molten rock cools deep under the surface of the earth?
These are igneous rocks.
What forms when molten material from beneath earth's surface cools but doesn't hardens?
When molten material from beneath the Earth's surface cools but doesn't harden, it forms a type of rock called volcanic glass, or obsidian. Obsidian is a black, glassy rock formed from rapidly cooled lava, which prevents the growth of mineral crystals typically found in other types of rock.
Is lava magma when it cools down?
Yes, magma is molten rock underground, while lava is molten rock that flows out of a volcano onto the Earth's surface. When lava cools down and solidifies, it becomes igneous rock.
When molten rock cools or hardens on or earth surface it forms?
Igneous
What happens when molten lava flows on the surface of earth?
It cools and forms new land.
How do rocks solidify from molten magma?
The same way any solid forms from a liquid - the liquid magma cools off and becomes solid. This usually happens when the magma comes to the cooler surface of the earth as lava, but it can occur very slowly inside of the earth as the magma gradually cools.
What forms when molten material from beneath Earth's surface cools and hardens?
When molten material from beneath Earth's surface cools and hardens, it forms igneous rocks. Igneous rocks can be either intrusive (formed underground) or extrusive (formed on the surface), depending on where the cooling and hardening process occurs.
What rock is formed when molten or liquid matter from inside the earth comes to the surface cools and hardens?
Depending on the heat either a igneous or metamorphic rock. If hotter then igneous then if cooler metamorphic
What liquid is below the surface of the earth?
The liquid below the surface of the earth is mostly molten rock, called magma. It is found in the mantle layer of the earth, between the crust and the core. The outer core of the earth is also a liquid, consisting mainly of molten iron and nickel.
What is the molten liquid rock inside the Earth's surface?
That would be called magma.
What kind of rock forms when hot molten rock cools deep under the surface of the earth?
These are igneous rocks.
What forms when molten material from beneath earth's surface cools but doesn't hardens?
When molten material from beneath the Earth's surface cools but doesn't harden, it forms a type of rock called volcanic glass, or obsidian. Obsidian is a black, glassy rock formed from rapidly cooled lava, which prevents the growth of mineral crystals typically found in other types of rock.
What is the definition of magma in science?
Magma is molten rock beneath the Earth's surface that can sometimes rise to the surface through volcanic activity. It consists of a mixture of liquid rock, crystals, and dissolved gases. As magma cools and solidifies, it forms igneous rocks.
Is lava magma when it cools down?
Yes, magma is molten rock underground, while lava is molten rock that flows out of a volcano onto the Earth's surface. When lava cools down and solidifies, it becomes igneous rock.
What Forms when molten rocks cools and hardens?
When molten rock cools and hardens, it forms igneous rock. Igneous rocks can be classified as intrusive (formed beneath the Earth's surface) or extrusive (formed on the Earth's surface). Examples of igneous rocks include granite, basalt, and obsidian.
