Pumice and Basalt
Igneous rocks are formed by the cooling and hardening of molten material called magma.
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.
An igneous rock has crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock). Igneous rocks are composed of minerals.
Igneous rocks are formed from the cooling of molten lava or magma. Sedimentary rocks are formed by the deposition and compaction of sediment grains or by their chemical precipitation in water. For more information please see the related link.
It is false. Granite is a igneous rock that was formed from magma cooling and hardening.

Igneous rocks are formed by the hardening of molten lava from a volcanic erruption. These rocks are also categorised by two types. One that is formed by rapid hardening / solidifying of lava eg. Granite and one that is formed by slow hardening eg. Basalt. These rocks have high density, strength and are bulky.
Igneous rocks are formed from magma or lava cooling and hardening. Sedimentary rocks are formed from sediments being compressed and cemented together. Metamorphic rocks are rocks that are changed by extreme heat and pressure.

By cooling and then hardening.
Sedimentary rocks: Rock formed when chemical reactions cement sediments (small, solid fragments of rocks and other materials) together, hardening them. Igneous rocks: Rock that forms from molten rock (hot magma thats cools and hardens). Metamorphic rocks: Igneous/sedimentary rock that has been changed into a new kind of rock as a result of great pressure and temperature.
Igneous rocks are formed through the process of heating and cooling beneath the earth's surface. This process involves molten rock (magma) cooling and solidifying to create igneous rocks such as granite or basalt.
Igneous rocks form when molten rock, known as magma or lava, cools and solidifies. This process can occur either underground, resulting in intrusive igneous rocks, or above ground, resulting in extrusive igneous rocks. The rate of cooling affects the size of the crystals within the rock.
