Extrusive igneous rocks.
igneous rocks
Rocks can be classified as either igneous or intrusive, but not both. Igneous rocks are formed from the cooling and solidification of magma (molten rock) above or below the Earth's surface. Intrusive rocks specifically form from magma that cools and solidifies underground, beneath the Earth's surface.
Igneous rock forms from molten rock that cools and solidifies, either above or below the Earth's surface. This process can result in the formation of rocks such as basalt, granite, and obsidian.
Igneous rocks form as a result of cooling magma. As the magma cools and solidifies, it forms rocks such as granite, basalt, and obsidian. The size of the mineral crystals in the rock is determined by the rate of cooling.
They are different because lava is when it hits earth's atmosphere; magma turns to lava. Magma is when its inside the volcano. They are different because of the color: darker/blacker and magma rocks are way hotter. Lava rocks are colder and fragile.

Rocks made from lava or magma are classified as igneous rocks. Igneous rocks form when molten rock cools and solidifies, either on the Earth's surface (extrusive) as lava or below the surface (intrusive) as magma. Examples of igneous rocks include basalt, granite, and obsidian.
When lava cools and solidifies.
Rocks can be classified as either igneous or intrusive, but not both. Igneous rocks are formed from the cooling and solidification of magma (molten rock) above or below the Earth's surface. Intrusive rocks specifically form from magma that cools and solidifies underground, beneath the Earth's surface.
Two types of igneous rocks are intrusive igneous rocks, which form from magma that cools and solidifies beneath the Earth's surface, and extrusive igneous rocks, which form from lava that cools and solidifies on the Earth's surface.
Igneous rock forms from molten rock that cools and solidifies, either above or below the Earth's surface. This process can result in the formation of rocks such as basalt, granite, and obsidian.
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.
Igneous rocks form as a result of cooling magma. As the magma cools and solidifies, it forms rocks such as granite, basalt, and obsidian. The size of the mineral crystals in the rock is determined by the rate of cooling.
Extrusive (Volcanic) igneous rock.
There are so many rocks that can be classified as not a common extrusive igneous rock. The most common extrusive igneous rock is basalt. Extrusive rocks are formed as a result of lava solidifying.
When metamorphic rock melts from pressure and heat, then the product of that melt solidifies, it is considered an igneous rock.
