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. Because this material solidifies and is still hot, it is buoyant and rises higher than the surrounding seafloor, creating the ridges. As it is pulled away from the spreading point by plate tectonics, it gradually cools, making it less buoyant; it gradually drops in elevation.
What else can I help you with?
New crust forms what kind of new boundaries?
New crust forms at divergent boundaries, where tectonic plates move away from each other. This process can occur in oceanic or continental crust.
What kind of sphere is the crust part of?
The Earth's crust is part of the lithosphere, which includes the crust and upper mantle. The lithosphere is a rigid layer that sits on top of the asthenosphere, a partially molten layer beneath it.
What is a fault the science kind?
crack in earths crust where two plates are sliding past each other
What kind of rocks make up continental crust and oceanic crust?
Continental crust is mainly composed of granitic rocks such as granite and rhyolite, which are light in color and less dense. Oceanic crust is primarily composed of basaltic rocks, specifically basalt, which are dark in color and more dense than granitic rocks.
What type of tool to go through a crust?
The type of tool I would use if I was doing this kind of question is a drill
What kind of crust is found under the ocean?
oceanic crust
What kind of crust are Plates made of?
rocky almost cement crust like granite found in continental crust and basalt found in oceanic crust
What kind of crust usually goes into the mantle?
Oceanic crust gets subducted into the mantle.
Where can mountains be created?
At breaks in the earths crust; like the tectonic plates; an earthquake can trigger a volcano, and depending on what kind of volcano it is, it can form a mountain.
What kind of forces can make a new mountain?
usually mountains are created by the earths tectonic plates pushing two parts of the crust together and upwards forming a mountain, this takes 1000s of years. Mountains are also created by magma coming through the crust (which turns into a volcano)
What kind of land you find on earth?
crust
What kind of pie crust should you use for the chocolate meringue pie?

When was the Pokemon Arceus made?
Sinnoh legends say Arceus was the one who created the universe, no-one created it, it kind of always existed.
