Answer:
The correct answer for this is B) Divergent Boundary
Explanation:
A divergent boundary is a rift beneath the ocean where two tectonic plates adjacent to one another begin to drift apart. If they do this long enough, it leads to the eruption of molten magma (basaltic molten rock) through the crevice created.
Answer
2. The answer is FALSE
Explanation:
Compressional tension refers to when two rock slabs, due to movements of the earth crust, crush against one another in a head-long fashion. The type of fault created is called reverse faults.
Normal faults, on the other hand, are caused by Tensional Stress which happens when the rock slabs due to tension grow apart.
Answer
3. The correct answer is B) Reverse Fault.
Explanation
Reverse faults happen as a result of compressional tension. This makes the footwall block or lower block to moves upwards relative to the position of the standing or hanging wall block.
Answer
4. the correct answer is A) Normal Fault
Explanation:
This is like an opposite of the Reverse fault. Whilst in the reverse fault the footwall block moves downwards relative to the position of the standing wall block, with a thrust fault, in this case, the hanging wall moves downwards relative to the position of the footwall block.
Answer
5. Triangulation is the method scientists use to locate the epicentre of an earthquake.
Explanation:
To do this, they have to compute seismic data from three or more locations. The data is plotted on a graph. The intersection point is taken as the epicentre. Seismic data is the information about an earthquake and is recorded for collection by on seismographs located across the world.
