_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 is the youngest part of earth's crust?
The youngest part of Earth's crust is found along mid-ocean ridges where new crust is continuously formed through volcanic activity. This process is known as seafloor spreading, where magma rises to the surface, cools, and solidifies to create new crust.
What are some features formed by glacial deposition?
Some features formed by glacial deposition include moraines (ridges of till), drumlins (elongated hills), eskers (sinuous ridges of sand and gravel), and kettles (depressions formed by melting ice blocks).
Where does the newest rock on earth occur?
The newest rocks on Earth can be found at places where volcanic activity is currently occurring, such as at mid-ocean ridges or volcanoes. These rocks are formed through the solidification of magma that reaches the Earth's surface.
At which type of plate boundary are mid-ocean ridges found?
Mid-ocean ridges are typically found at divergent plate boundaries, where tectonic plates are moving away from each other. These ridges are formed by the upwelling of magma from the mantle, creating new oceanic crust as the plates separate.
What is the definition of rifts and ridges?
Rifts are long cracks in the Earth's crust caused by tectonic activity that can lead to the formation of new ocean basins. Ridges are underwater mountain ranges formed by the upwelling of magma at divergent plate boundaries. Both rifts and ridges are associated with the process of seafloor spreading.
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
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 ;)
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
Ridges of sand formed by the wind are called?
helo
How did floridas ridges form?
it formed from ancient sand dunes.
Where is the newest ocean crust formed?
mid ocean ridges
