Answer:
B. Stress caused by forces that stretch an area of the crust made the rock to break
Explanation:
From the picture inserted to this problem, we see a unit that has been severely fractured.
Fracturing results from the brittle deformation of a rock under applied stress.
- Rock fracturing results in the formation of joints and faults.
- We can obviously see different sets of joint sets on the body of the rock in the picture attacked.
- Also, a prominent fault which resembles an extensional fault can also be seen.
- Therefore, the stress caused the stretch of the area which in turn makes the rock the rock to break.
When oxygen is absent, anaerobic respiration occurs ('an' means without).
Energy travels through a food chain/web. When an organism eats another organism, the energy from the food is passed to the eater. For example, we humans eat food to give ourselves enough calories (energy) to function properly.
