Due 05/08/20 11:59pm
in science class. Ethan and his friends are creating posters. The posters will show where various fuels are
found and how they are formed.
Coal
What can be added to the drawing to show the original source of the energy found in the fuel?
A rocks breaking down into minerals
B. people mining the coal
O
C
the motion of flowing water
O
D
sunlight shining on Earth

The poster has not been given in the question and is also not found anywhere else but based on the knowledge of coal formation the correct option can be predicted.

Sunlight shinning on Earth (Option D)

Explanation:

Coal formation takes place inside the earth. It takes hundreds of years for its formation. The plant and animal debris under extreme temperature and pressure gets converted into coal which is extracted and used as source of energy.

Adding a sun in the poster can help to show the growth of plants which helps the growth of animals as well. Plants make food that is consumed by animals. When these plants and animals die, they are buried or gets buried inside the earth.

This is how the process of coal formation starts and hence, the correct answer would be option D.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
