Explanation:
Aftershocks are earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 fault lengths distance from the mainshock fault.
Foreshocks are relatively smaller earthquakes that precede the largest earthquake in a series, which is termed the mainshock.
Answer:
B.sea floor spreading
Explanation:
The creation of new crusts at the middle of the mid- ocean ridges is also sea floor spreading.
The process of sea floor spreading entails the creation of new crusts at the margin of the oceanic crusts.
Basaltic materials from the subsurface upwells to the surface.
They cool and solidifies to form new crusts. The old crust is moved behind and away from the margin. This way, sea floor is formed and it spreads in like manner.
At this margin sea floor is created and at a convergent margin, it is destroyed.
Cells know how to differentiate through a process called gene expression. It’s a specific combination of genes that are turned on and off.
