The crust actually accounts for less than 1 percent of the volume of the Earth. The Earth can actually be divided into four parts and they are crust, mantle, outer core and inner core.
Answer:
Option (3)
Explanation:
Mid-oceanic ridges are the regions along which two distinct plates move away from one another. This type of plate boundary is known as the divergent plate boundary.
Whereas a rise occurs along a divergent plate boundary and is mostly associated with the region of hot-spots, where the magma is forced to rise up forming a gently steeper underwater highland area.
Both these features occur in a divergent plate boundary and plays an important role in pushing the continents apart. So we can conclude that the rises are mostly associated with the region of hot-spots, and ridges are formed due to the seafloor spreading at divergent plate boundaries.
Hence, the correct answer is option (3).
