Lava flows from the rifts and is cooled quickly by sea water
What else can I help you with?
Why does lava cool rapidly along a mid ocean riege?
Because it is near the ocean
What happens to lava when it enters the ocean?
On contact with water lava will cool rapidly to form rock.
Why do warm ocean currents cool as they flow along a coastline away from the equator?
Warm ocean currents cool as they flow along a coastline away from the equator because sand and minerals are transported by ocean currents away from the equator.
How do the mantle's convection currents move to form a mid-ocean ridge?
The mantle's convection currents move in the mantle in the form of magma which creates the mid-ocean ridge. Mid-ocean ridges are found in every ocean in the world and when the currents erupt as lava the eventually cool and create a crust.
Why ocean breezes cool the land along the coast in the summer?
Because it is deal with it.
How is magnetic evidence preserved in the rocks that form along an ocean ridge?
Iron minerals that are present in magma or lava along the ridge that has not completely crystallized into rock are aligned with the Earth's polarity. When the magma or lava cools and solidifies completely, the magnetic orientation of the Earth at that time is preserved in the body of igneous rock.
What is Mid Atlantic?
The mid ocean ridge is where the tectonic plates are moving apart in the middle of the ocean causing magma to come to the surface and cool making new seafloor in it's place.
What is mid Atlantic rige?
The mid ocean ridge is where the tectonic plates are moving apart in the middle of the ocean causing magma to come to the surface and cool making new seafloor in it's place.
What structure on the seafloor would have magnetic striping?
A mid-ocean ridge would have magnetic striping on the seafloor. This striping is caused by the alternating polarities of Earth's magnetic field recorded in the basaltic rocks as they cool and solidify at the mid-ocean ridge, providing evidence for seafloor spreading.
What is transported when warm ocean currents cool as they flow along the coastline away from the equator?
Water
Why are ocean currents important to coastal regions?
they can warm or cool the air temperature along the coastal regions.
How do minerals form from solutions along the mid ocean ridge.?
Mineral formation can occur several ways along the MOR. Rising magma can cool and crystallize, forming igneous rock which contains various minerals. Heated seawater also percolates through the hot rock of the MOR, and can precipitate minerals on rock surfaces and at black smokers.
