Answer 1

Coal

Step-by-step explanation:

Coal is formed from plants trapped in dust and dirt for a long time, so coal would fit plant material, and it also takes a long time to make coal, that's why it will run out at some point

Answer 2

Cementation

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place :)
