Answer: A. Geological processes continue over millions of years.
A swamp is a wetland which exhibit the growth of vegetation. It consist of vegetation which is being dominated by trees. When these trees die, the wooden parts sank below the water. The wood remains being deposited at the bottom of the water body causes the formation of coal. Coal formation results due to the wood being compressed and buried. It takes millions of years for the transformation of wood into coal in the geosphere of the swamp region.
Hence, formation of coal is a geological process and it takes millions of years for it's formation.
Answer:
All living things
Explanation:
Climate affects everything
The electrons in the outermost shell of the covalent compounds are shared by nearby atoms. As there are no free electrons for conducting electricity, the covalent compounds are perfect insulators at absolute zero. As the temperature increases, some electrons move from valence band to conduction band. This gives rise to conductivity. But as the numbers of charge carriers are very low, covalent compounds are poor conductors. On the other hand metals are good conductors cause of their bonding. Metallic bonding consists of a sea of electrons rather than discreet bonds. The free electrons are able to move freely. Since electricity and heat need electrons to move, the bonding promotes conductivity.
