Answer:
Normal fault
Explanation:
Tensional stress occurs as a result of forces which could be wind, water etc pulling the rocks apart and forming faults. Faults are also known as a type of fracture which occurs between rocks.
Tensional stress along a fault can result in a dropped hanging-wall block relative to the footwall side(in a perpendicular position) thereby producing a normal fault.
The texture of the rock in the attached image is indicative of the fact that the magma from which it was formed was filled with dissolved gas.
<h3>What is magma?</h3>
Magma is simply rock in its molten state. It is also known as molten magma.
During the process of solidification. the dissolved gases in the molten magma find routes of escape thus leaving a very coarse texture the surface of the rock.
