Which sedimentary rock forms from the compression of swamp material?

Coal

Explanation:

The rock is formed from organic matter. The material that accumulates in the swampy areas is used in making coal. Therefore the plants that form coal lived both in the modern and in the dinosaurs’ time. When the plants perish they sink to the bottom of the swamp and become buried by the soils. After an extended period, the plant material goes more rooted to the ground and gets changed because of heat and pressure. The pressure and temperature makes the plant material to be in a solid form resulting in coal.

the answer is "d"

(context) if you were to travel to the middle east and go into peoples homes there would be like 4 generations in there

(more context) i'm pretty sure in the middle east they take loyalty and family bonds very serious

(last bit of context) i'm also positive that extended families are most commonly found in urban areas
