Ridges and Rises are uplifts in oceanic crust caused by volcanic eruption in oceans, the difference between a ridge and a rise is of rift valleys, ridges have long valleys and rises do not have any valleys

Why do oceanic rises and oceanic ridges exist?
They are located at spreading centers in the middle of the ocean. As tectonic plates move apart, magma fills it in and creates ridges and rises which are essentially mountain chains.
What is called when new crust forms where magma rises at mid ocean ridges?
sea floor spreading
What is the definition of mid ocean ridges?
Mid-ocean ridges are a line of volcanic mountains under the oceans between the continents. As the oceanic plates are being pulled apart by the processes of plate tectonics, magma is formed from decompression melting in the mantle, and rises upward to fill in the gap that is created.
What is located in midocean ridges?
The Mid-Atlantic Ridge is found on the ocean floor in the middle of the Atlantic Ocean.
Where are mid ocean ridges?
They are found at a plate boundary. When two plates move apart (divergent) magma rises through the gap.
Mid-Ocean ridges are found where?
They are found at a plate boundary. When two plates move apart (divergent) magma rises through the gap.
Why are there volcanoes at mid ocean ridges?
Mid-ocean ridges and seamount relates to volcanoes by both having lava and it also comes out and cools
At a divergent boundary land is gained or lost?
At a divergent boundary, land is gained. Ocean ridges are prominent at divergent plate boundaries. Ocean ridges are areas of seafloor spreading. Seafloor spreading occurs as upwelling magma rises to the surface. This upwelling magma hardens and forms new seafloor.
Is new oceanic crust formed at a mid-ocean ridge?
The answer to that question is the following:=Magma rises toward the surface and solidifies=
What area is between the continental slope and ocean basin?
continental rises
How are epidermal ridges formed?
Ridges may form when two land masses push together from plate tectonics, earthquake upheaval, volcanic action, or similar geological events. Some ridges are the results of weathering or erosion, where harder rock remains after the surrounding softer terrain has washed away.
What material that rises to surface at mid-ocean ridge?
Sea-floor spreading due to convection currents in the Earth's mantle (although this is still under investigation). Magma is pushed up through the cracks in the sea-floor as the plates move apart.
