Hardened lava is called igneous rock. When lava cools and solidifies, it forms igneous rock through the process of crystallization. This rock can have different textures and compositions depending on the speed of cooling and the mineral content of the original lava. Examples of igneous rocks formed from lava include basalt, andesite, and rhyolite.
Melted rock is that hasn't surfaced is "Magma".If the melted rock already has surfaced, it is called "Lava".
Good question! According to Dana's Manual of Mineral Science (the Bible of minerals, in a way) a mineral must be solid. So, lava, which is not solid, is not a mineral. Once lava hardens into a solid, it becomes a rock made of different types of minerals.
why does the lava sink or rise?
The way fossils are formed in very dry places is called mummification. Amber is a hardened tree sap, yellow to brown in color, and often a source of insect fossils.
Molten rock in any of Earth's layers is called magma. The mantle is actually composed of solid, but very hot and plastic-like rock.
The hardened layer of lava is called "igneous rock".
A hardened layer of magma is called a lava flow or volcanic rock.
Hardened lava is considered igneous rock, composed of minerals.
Cooled lava is called a igneous rock once it has completely cooled and hardened. Some people just call it lava rock.
This is called a lava tube.
Molten rock is magma. It is called lava once it has cooled and hardened.
The cycles are molten rock, lava, and then hardened lava like obsidian.

Hardened lava typically ranges from about 600 to 1200 degrees Celsius (1100 to 2200 degrees Fahrenheit), depending on the type of lava and cooling conditions.
The particles in a hardened lava sample will be solidified and compacted, while the particles in a liquid lava sample will be molten and in a flowing state. The hardened lava particles will have a crystalline structure, whereas the liquid lava particles will lack a fixed arrangement due to their high temperature.
Magma is underground, when it reaches the surface it becomes lava. So solidified magma is really lava. The lava flow is the liquid lava as it goes down the mountain, when hard its just hardened lava.

The cooled lava pools on the surface of a crater are called "lava lakes." These formations occur when lava accumulates in a depression and solidifies, creating a hardened surface. In some cases, the lava lakes may still be active and exhibit volcanic activity beneath the surface.
