down in the sea is something called lava that grows into the ocean floor it puts on at least 2 1/2 cm each year
New oceanic crust is continually being created at the Mid-Ocean ridges.
At the divergent plate margin know as the mid-ocean ridge. At these locations, areas between spreading oceanic plates are infilled with new crust from rising mantle material.
This happens when two tectonic plates move apart and magma wells up between them and sets.

Place where seafloor spreading occurs?
Seafloor spreading occurs at the boundary between two tectonic plates. As the plates divide, magma comes up through the crack and cools to form new sea floor. The farther away the floor is from the boundary, the older it is.
An underwater mountain chain that formed by sea-floor spreading is called a?
Underwater mountain chains that form where two tectonic plates are pulling apart are called mid ocean ridges. The largest is the Mid Atlantic Ridge.
How did Harry Hess contribute to science?
Harry Hess's discovery was important because it helped explain the theory of continental drift. His discovery, that on the sea floor magma pushes up which causes the plate tectonics to move which carries the continents with it, explains better reasoning to the theory. It also helped the scienctist to explain how the sea floor spreading is happening.
Explain how scientist tink most magma is formed?
Magma is formed from the subduction and melting of cold, dense, wet oceanic crust at some convergent plate margins. The moisture in the rock assists in the melting of the crust and the rock surrounding it. Magma is also formed at hot spots in the mantle where hot material undergoes decompression melting as it rises. Decompression melting also occurs at the mid-ocean ridges where new oceanic crust is formed from rising mantel rock.
What is a undersea mountain chain were new ocean floor is produced?
A mid-ocean ridge is an undersea mountain chain where new ocean floor is produced through volcanic activity. Here, magma rises up from the Earth's mantle and solidifies as it cools, leading to the formation of new crust.
Why the crust is thinner than the ocean floor?
The Earth's crust is thinner than the ocean floor because the oceanic crust is formed at mid-ocean ridges where heat from the mantle creates new crust through volcanic activity. This process creates younger, hotter, and thinner crust in the ocean compared to the older and thicker continental crust.
How do constructive forces help the earth?
They could help in creating new lithospheric (crust) plates. As in the case of divergent boundary, where new ocean floor is produced and expanded (sea-floor spreading).
New crust forms on the ocean floor due to what process?
New crust forms on the ocean floor through seafloor spreading, where magma rises up from the mantle through mid-ocean ridges and solidifies into new crust as tectonic plates move apart.
Which geologic process forms new crust on the ocean floor?
Seafloor spreading is the geologic process that forms new crust on the ocean floor. This occurs at mid-ocean ridges, where tectonic plates move apart and magma rises to the surface, solidifying to form new oceanic crust.
Does sea floor spreading create or destroy new oceanic crust at mid ocean ridge?
Sea floor spreading creates new oceanic crust at mid-ocean ridges. Magma rises to the surface, cools, and solidifies to form new crust as tectonic plates move apart. This process contributes to the continuous expansion of the ocean floor.
The process of continually adds new crust to the ocean floor along both sides of the mid-ocean ridge.?
sea floor spreading
The youngest rocks on the ocean floor are located?
The youngest rocks on the ocean floor are located at mid-ocean ridges, where new oceanic crust is formed through volcanic activity. As the crust spreads away from the ridge, it gets progressively older. This process is known as seafloor spreading.
Where is the youngest ocean floor in the mid-Atlantic ridge?
Down the middle! The mid Atlantic ridge is a divergent plate margin along which new crust is constantly being produced.
How does sea floor spreading alter the shape of the ocean floor?
Sea floor spreading occurs when new oceanic crust is formed at mid-ocean ridges and pushes the existing crust apart. As the new crust cools and solidifies, it creates a symmetrical pattern where the ocean floor becomes wider. This process alters the shape of the ocean floor by creating a series of parallel ridges and valleys.
Vine and Matthews determined that new ocean floor was being produced at ocean ridges by examing?
the magnetic pattern on the sea floor
What process adds new crust to the ocean floor?
Volcanic eruptions are one process that adds new material to crust. Lava from the volcanoes eventually cool, forming new land. Sea floor spreading also adds new material to the crust.
