The hazards from the volcanoes include lava and pyroclastics, tephra and , lahars and climate alteration. Fertile soil and geothermal energy are beneficial results of volcanic eruptions. Much of El Salvador for example is convered with volcanic ash and this has been a fertile growing medium for coffee plants.
Answer:
place, space, and scale
Explanation:
A geographer investigate issues from the view point of location according to place, space and the scale.
The place is an element of location that describes the position or the domain of occurrence of issue.
Space refers the area occupied by a body or the area where an issue is domiciled.
The scale refers to the magnitude at which an issue is view or observed.
Geographers tends to synthesize and combine these different lenses to observe and investigate an issue. Almost everything on earth can be correlated spatially using these lenses.
The subject of science is very broad. With that being said, I think there is no official regulatory board that decides the branches of science. Scientific developments are products of joined efforts of different scientists. These scientists could rebuke another's work provided there is evidence. As long as the theory is generally accepted by the scientists and no one rebukes it effectively, then it is a generally accepted fact and everyone adapts it.
Hence, the answer is B.
