Different types because they formed in different ways.

Yes, if sedimentary rock is moved below Earth's outer layer and exposed to energy from Earth's interior, it can melt into liquid rock and form igneous rock.

Energy from different sources leads to different types of rocks. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces of rock.

Wind and rain interacted with the rock, breaking it into small pieces.

It was heated and put under pressure.

The rock is not likely to change very much. Most rock formation processes happen very slowly.

One plate went underneath the other plate and sank into the soft rock below.

Wind and rain interacted with the rock, breaking it into small pieces.

Yes, if igneous rock is moved to Earth's surface and exposed to Energy from the sun, it could weather into small rock pieces that could form sedimentary rock.
