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 most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
