How are extrusive rocks formed?

Magma gets trapped inside Earth and cools to rock

Volcanoes apply force to solid rocks and eject them.

Magma gets forced to Earth's surface and cools to rock

Volcanoes trap lava inside Earth, where it cools to rock

It would be Magma gets forced to Earth's surface and cools to rock.

Explanation:

Magma doesn't get "trapped" inside Earth, it latches itself to the Earth's surface and when it reaches to that part of the Earth, it starts cooling down to be describes as an extrusive rock (s).

The extrusive rocks are rocks that have been formed by the very quick cooling of the magma on the surface, be it on land or in water. The magma practically gets pushed towards the surface, and because the surface is much cooler, the magma cools off very quickly and forms the extrusive rocks.
