The magma (lava) solidifies as it cools, forming extrusive igneous rock; in this case, the rock basalt. In the slow dance of plate tectonics, the newly formed crustal rock is pulled away from the mid-ocean ridge, replaced by newer solidifying basaltic lava.

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.


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.


Mid ocean ridges form where tectonic plates do what?

Mid-ocean ridges form where tectonic plates diverge, or move apart. This process allows magma from the mantle to rise to the surface, creating new oceanic crust as it cools and solidifies. The continuous movement of the plates at these ridges contributes to seafloor spreading and the dynamic nature of the Earth's lithosphere.


Where do oceanic plates touch on earth?

Oceanic plates typically touch at mid-ocean ridges, where new oceanic crust is formed as magma rises from the mantle and solidifies. Additionally, oceanic plates can also interact at subduction zones, where one plate is forced beneath another, leading to the formation of deep ocean trenches and volcanic activity.


When crustal plates collide at ridges one plate rides up over the other plates?

When crustal plates collide at ridges, typically at divergent boundaries, one plate can be forced upward as it subducts beneath another. This process creates geological features such as mountains or ridges. The interaction between the plates leads to volcanic activity and the formation of new crust as magma rises to the surface. Additionally, the movement of these plates can cause earthquakes, further reshaping the landscape.

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.


Where are the midocean ridges offset the most by faults?

At transform faults or transform zones.


When the sea floor spreads apart volcanoes and ridges are formed because?

"as the plates pull apart, magma moves to the surface, building ridges"


What happens when new basalt forms along mid ocean ridges?

Magma that has bubbled up through the crack in the Earth's surface.

What happens when earth's plate move?

when the earths plates move we either have earthquakes, tsunamis, and we get ridges and trenches.

Where is top of the asthenosphere closest to Earth's surface?

The top of the asthenosphere is closest to Earth's surface beneath mid-ocean ridges, where tectonic plates are moving apart. This is where the asthenosphere is pushed up towards the surface due to the divergent motion of the plates.

What cause ocean ridges to form?

Ocean ridges form as a result of tectonic plate movement and divergent boundaries where two plates move apart. Magma rises to the surface between the plates, creating new oceanic crust that forms a ridge. This process, known as sea-floor spreading, leads to the continuous growth of the ocean ridges.
