How do ridges and rises differ? Rises are broader and more gently sloped than ridges. Divergence occurs more quickly at a ridge.
Rises are associated with hotspots, and ridges result from seafloor spreading at divergent plate boundaries. Ridges are associated with divergence, and rises are associated with convergence. Ridges occur in the Pacific Ocean, and rises occur in the Atlantic Ocean.
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.
