What do the slits represent?

The side slits stand for where subduction has occurred and the ocean floor has sunk in. Also, the space under the paper stands for the oceanic crust of the Earth.

What occurs in the mid-ocean ridge?

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

What processes happen at the side slits as the new seafloor form at the mid-ocean ridge?

Seafloor spreading or Seafloor spread is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

What does the stripes stand for in seafloor spreading?

What do stripes represent for seafloor spreading? the stripes represent the rocks with normal and reverse polarities. 23. the middle split represents the mid-ocean ridge where the actual seafloor spreading occurs.

What occurs at mid-ocean ridges quizlet?

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

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 feature of the ocean floor does the center slit stand for what prominent feature of the ocean floor is missing?

What feature on the ocean floor does the center slit stand for? central valley of mid-ocean ridge where molten material is upwelling from below.

What’s the bottom of the sea called?

The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as ‘seabeds’.

What type of plate boundary is occurring in the Mid Atlantic Ridge?

divergent plate boundaries
The Mid-Atlantic Ridge is an example of divergent plate boundaries. When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.

What is the role of the mid-ocean ridge in the movement of lithospheric plates?

Mar. 17, 2021 — Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth’s interior push tectonic plates apart, forming new ocean floor and thus moving continents about.

What process is involved when the oceanic crust plunges down into the mantle?

The process by which the ocean floor sinks into the mantle is called Subduction ..

What happens when the oceanic plates continuously moving away from the mid-ocean ridge?

As oceanic crust moves away from the shallow mid-ocean ridges, it cools and sinks as it becomes more dense. This increases the volume of the ocean basin and decreases the sea level.

What is split and separate?

As verbs the difference between separate and split

is that separate is to divide (a thing) into separate parts while split is (ergative) of something solid, to divide fully or partly along a more or less straight line.

What happens to the molten rock from the mantle at the mid-ocean ridge?

Beneath a typical mid-ocean ridge, mantle material partially melts as it rises in response to reduced pressure. … Much of the magma eventually freezes in place there within the crust, forming the bulk of the new oceanic crust without erupting at all.

Is the mid-ocean ridge underwater?

The mid-ocean ridge is a continuous range of undersea volcanic mountains that encircles the globe almost entirely underwater.

How do you split and separate activities?

How does the new seafloor form at the ridge?

How does new seafloor form at mid-ocean ridges? As the seafloor spread apart at magma is forced upward and flows from new seafloor. As new seafloor moves away from the mid-ocean ridges, it cools, contracts, and becomes denser. This denser, colder seafloor sinks, helping to form the ridges.

What boundary is a trench?

convergent plate boundaries
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

Why are mid-ocean ridges elevated?

Why Are Mid-ocean Ridges Elevated??

Since hot rocks are in a more expanded state and then contract as they cool (as they spread away from the ridge), the midocean ridges stand up high above the surrounding seafloor. The seafloor depth increases with distance away from the midocean ridges.

What is the longest mountain range Earth either on land or underwater?

The mid-ocean ridge is the longest mountain range on Earth.

Spanning 40,389 miles around the globe, it’s truly a global landmark. About 90 percent of the mid-ocean ridge system is under the ocean.

Where is the youngest ocean floor found?

the mid-ocean ridge
Where is the youngest ocean floor located? The youngest ocean floor is located on the mid-ocean ridge.

Where is the ocean deepest?

The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
