Does magma produce new material when it rises from an ocean ridge?
Yes, when magma rises from an ocean ridge, it can produce new material through a process called seafloor spreading. As the magma reaches the surface, it cools and solidifies, forming new oceanic crust. This process contributes to the continuous expansion of the seafloor and the formation of new crustal material.
In sea-floor spreading molten material rises from the mantle and erupts .?
When spreading molten material rises from the mantle in the sea-floor and erupts, it can create sea mounts, which are underwater mountains. If enough material is ejected, the mounts will break through the surface of the water to create islands.
What is an underwater ridge of coral or rock that rises close to the surface?
it is a REEF
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.
What are the steps in the process of sea-flooring?
The sea-floor spreading begins at the mid-ocean ridge, which forms along a crack in the oceanic crust. Along the ridge, molten material that forms several kilometers beneath the surface, rises and erupts. At the same time, older rock moves outward on both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. When more molten material flows into the crack, it forms a new strip of rock.
What are the steps in process of sea floor spreading?
In sea-floor spreading,the sea floor spreads apart along both sides of the mid-ocean ridge as a new crust is added.As a result,the ocean floors move like conveyor belts,carrying the continents along with them.
Why doe partly molten material rise toward earth's surface?
Less/dence material rises
What do you call an underwater ridge that rises up close to the earths surface?
An underwater ridge rising close to the surface is called a reef. A reef is typically made of rock, sand or coral that lies 80 meters or less beneath low water.
Melted material that rises from the mantle is called?
Melted material that rises from the mantle is called magma. Once magma reaches the Earth's surface, it is then referred to as lava.
What is it called when hot material rises to the sun's surface?
it is called the art of materilintasion which was discovered by the neanderthals
What Is A Good Sentence For Mid-Ocean Ridge?
The Mid-Ocean Ridge Is From The Mantle.
Where does molten material that rises from the mantle erupt?
it erupts from the mantle witch is part of the structure of the earth.
