What is a mid-ocean ridge simple definition?
What is a mid-ocean ridge simple definition?
Definition of mid-ocean ridge : an elevated region with a central valley on an ocean floor at the boundary between two diverging tectonic plates where new crust forms from upwelling magma.
What is an example of mid-ocean ridge?
Two of the most well-known mid-ocean ridges are the Mid-Atlantic Ridge and the East Pacific Rise. As you might guess, most of the Mid-Atlantic Ridge is in the Atlantic, and most of the East Pacific Rise is in the Pacific.
How does mid-ocean ridge form?
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.
What does a mid-ocean ridge do?
Mid-ocean ridges are considered the planet’s largest magmatic system. At divergent plate boundaries, magma is generated by decompression melting of upwelling mantle. Melts are focused as they ascend through the upper mantle and lower crust and collect beneath the ridge axis in elongate melt lenses.
What is a mid-ocean ridge for kids?
The mid-ocean ridge is formed where two tectonic plates meet under the ocean. This divergent boundary creates mountains, valleys like the famous rift valley, volcanoes, and sometimes earthquakes. It stretches all around the Earth, is home to many strange animals, and still has a lot to be explored.
Which is characteristic of mid-oceanic ridges?
A mid-ocean ridge (or mid-oceanic ridge) is an underwater mountain range, typically having a valley known as a rift running along its axis, formed by plate tectonics. This type of oceanic ridge is characteristic of what is known as an oceanic spreading center.
What are ocean ridges kids?
An oceanic ridge is an underwater mountain range, usually formed by plate tectonics. They are geologically active, with new magma constantly emerging onto the ocean floor through a gap called a rift in the earth’s crust. In most instances, it accumulates and forms new crust.
Are mid-ocean ridges volcanoes?
The mid-ocean ridge is a continuous range of undersea volcanic mountains that encircles the globe almost entirely underwater.
What are mid-ocean ridges quizlet?
mid-ocean ridge. an undersea mountain chain where new ocean floor is produced at a divergent plate boundary.
How does each plate get its name?
The Earth is always on the move due to the motion of the tectonic plates. Seven of the major plates make up most of the seven continents and the Pacific Ocean. They are named after nearby landmasses, oceans, or regions.
What rocks form at mid-ocean ridges?
Igneous rock is formed by the cooling and crystallization of molten magma at volcanoes and mid-ocean ridges, where new crust is generated.
