Coal is formed in which of the following depositional environments

Hello. This question is incomplete. The complete question is:

"Coal is formed in which of the following depositional environments

A. A glacier , B. A swamp , C. A beach , D. A river channel"

B. A swamp

Explanation:

Coal is a mineral that formed millions of years ago. The process of its formation took place from trunks, roots, branches and leaves of giant trees. All these plant fragments, after they died, were deposited and buried by sediment. Through great pressure and extremely high temperatures, they gradually turned into coal ore 300 million years ago.

According to this we can say that, among the options given in the question above, the one that is a possible place for the formation of coal is a marsh. That is because the marsh is a place with stop plants that will enter the process of senescence and decomposition, creating the perfect environment for coal formation.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
