If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
No, they do not form on the surface of the Earth. They are formed by the crystallization of magma within the Earth. All you have to remember is an intrusive rock forms within the Earth.
The type of rock that forms at the edges of cooling magma chambers within the Earth is called igneous rock. Specifically, when magma cools and solidifies slowly beneath the Earth's surface, it forms intrusive igneous rocks, such as granite. If the magma erupts to the surface and cools quickly, it forms extrusive igneous rocks, like basalt. The cooling process and composition of the magma determine the specific characteristics of the resulting igneous rock.
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.
The molten material moving upward within the Earth's crust is called magma. Magma is formed from the melting of rocks in the Earth's mantle and can rise to the surface through volcanic activity. As magma cools and solidifies, it forms igneous rocks.
Volcano lava forms as rocks as it cools down. Rocks are formed with magma and lava which when cooled down would form as rough matters. Rare lava parts are formed up like ruby, diamonds, and even emeralds.

When melted rock cools and hardens in or under the Earth's surface, it forms igneous rock. This process can happen above ground, forming volcanic rocks, or below ground, forming intrusive rocks.
The molten material moving upward within the Earth's crust is called magma. Magma is formed from the melting of rocks in the Earth's mantle and can rise to the surface through volcanic activity. As magma cools and solidifies, it forms igneous rocks.
Igneous rock forms when melted rock (magma) from inside the Earth cools.
Volcano lava forms as rocks as it cools down. Rocks are formed with magma and lava which when cooled down would form as rough matters. Rare lava parts are formed up like ruby, diamonds, and even emeralds.

Feldspar can be found in both extrusive and intrusive igneous rocks. In extrusive rocks, feldspar forms when magma cools and solidifies quickly on the Earth's surface. In intrusive rocks, feldspar forms as magma cools and solidifies slowly beneath the Earth's surface.
Magma that cools underground forms igneous rocks.* It is called "lava" when it reaches the surface, and may solidify into several forms of igneous rock, depending on the compounds found in the magma and how it cools.
When magma cools slowly below Earth's surface, it forms rocks with large crystals. This slow cooling allows more time for crystals to grow to a larger size compared to rocks that cool quickly at the surface. Examples of these rocks include granite and diorite.
