basalt
Such rock is extrusive igneous rock.
When igneous rock forms on the Earth's surface, including on the ocean floor, it's called extrusive. It's called intrusive rock when it forms beneath Earth's surface, such as in mines.
The rock that forms from the cooling of lava is called igneous rock. When lava cools and solidifies on the Earth's surface, it is specifically referred to as extrusive igneous rock, such as basalt. If the lava cools slowly beneath the surface, it forms intrusive igneous rock, like granite.
Magma is molten rock beneath the Earth's surface, while lava is molten rock that flows onto the surface during a volcanic eruption. When magma cools and solidifies underground, it forms intrusive igneous rocks, such as granite. When lava cools and solidifies on the surface, it forms extrusive igneous rocks, such as basalt.
Igneous rocks do form on the earths surface. A volcano erupts and the lava that comes out cools and hardens forming igneous rocks.
Such rock is extrusive igneous rock.
extrusive igneous rock
This type of igneous rock is called "extrusive igneous rock." It forms when lava cools and solidifies quickly on the Earth's surface, resulting in small mineral grains that are characteristic of rocks like basalt or rhyolite.

The igneous rock forms from lava because when a volcano erupts the lava that flows from a volcano. Igneous rocks have a hot liquid in the beginning. The lava that flows forms into an igneous rock fast. When the lava reaches the surface, it cools rapidly and turns into igneous rock.
Igneous rocks do form on the earths surface. A volcano erupts and the lava that comes out cools and hardens forming igneous rocks.
Yes, an igneous rock forms when lava is cooled. It is called an extrusive igneous rock (because lava is extruded onto the surface of the earth). A magma pool that did not erupt as lava can cool to become an intrusive rock.
Volcanic (Extrusive) igneous rock, which are formed by lava that comes out of the earths crust, then cools and solidifies rapidly on the earths surface due to exposure to the environmental atmosphere.
When molten rock erupts onto Earth's surface, it forms lava flows and igneous rock formations. The type of igneous rock formed depends on the composition of the magma and the speed of cooling. Each eruption can create unique landforms like volcanoes, lava plateaus, and volcanic islands.
igneous with small crystals. Extrusive igneous rock forms from the solidification of lava. Rocks such as rhyolite, pumice, obsidian, and basalt. Igneous rocks are formed by magma (inside the earth) or lava (outside earth) that cools and hardens. Extrusive rocks are rocks thathave exited the earths surface.
Igneous rock forms from the solidification of magma and lava; this can occur at or below the surface.
