_Seafloor Spreading_
1. Hot, molten rock is forced upward toward the seafloor at a mid-ocean ridge.
2. Molten rock pushes sideways in both directions as it rises, moving the mantle with it.
3. Molten rock flows onto the seafloor and hardens as it cools.
4. New seafloor moves away from the ridge, cools, becomes denser, and sinks.

What are ocean ridges formed by?
Divergent boundaries
What is the youngest part of earth's crust?
The youngest parts of the Earth's crust are the midocean rifts. It is approximately 1,500 km wide, 1 to 3 km high, and over 84,000 km long.
Where are oceanic crust and lithosphere formed?
At the mid-ocean ridges.
Mid ocean ridges are actually underwater mountain ranges?
It is true that mid-ocean ridges are underwater mountain ranges. These ridges are where the lithosphere is moving apart and new oceanic crust is being formed.
Where is new lithosphere formed?
New lithosphere is commonly formed at mid-ocean ridges, hot spots, and where there are active volcanoes.
Where do midocean ridges intersect the landmasses?
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
Where are the midocean ridges offset the most by faults?
At transform faults or transform zones.
Is the Mid-Oceanic Ridge in the middle of the Atlantic Ocean?
One of the midocean ridges is, but others are in other oceans, seas, and bays.
Do Ocean sediments become younger or older away from midocean ridges?
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
What are the 3 type of earthquakes?
(1)midocean spreading ridges, (2) subduction zones, and (3) transform faults.Normal fault, Reverse fault, and strike-slip fault
Ocean ridges are formed by what boundaries?
Divergent boundaries form ocean ridges.
When was MidOcean Partners created?
MidOcean Partners was created in 2003.
What are the differences between ocean ridge and seamount?
The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.
What are mid ocean ridges formed from?
the wind ;)
What are ocean ridges formed by?
Divergent boundaries
What is located in midocean ridges?
The Mid-Atlantic Ridge is found on the ocean floor in the middle of the Atlantic Ocean.
How are mid Atlantic ridges formed?
It was formed when there was linear gap formed below at the ocean floor... So when the hot magma came out from it, it began to cool and solidify forming mid atlantic ridges
