Explanation:

A student of ecology researched about the low growth of algae in the Big Moose lake as compared to the Brant lake, though Big Moose lake has higher  level of nitrogen and nutrients in it.

Nitrogen and phosphorous are an important element for the growth of algae in water bodies but in presence of pollutants in  the water bodies and low oxygen content, the algae grows in slower rate.

Which of the following explains how fault is formed?
lord [1]

Answer:

a. Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.

Explanation:

The correct answer is - a.Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.

Reason -

A fault is a fracture or zone of fractures between two blocks of rock.

Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.

During an earthquake, the rock on one side of the fault suddenly slips with respect to the other.

The fault surface can be horizontal or vertical or some arbitrary angle in between.
