What happens to plates as they move away from the mid ocean ridge?
Plates of the earth's crust are moving away from each other, forming an extensive system of fractures and faults.
When magma cooled on surface?
Magma doesn't cool on the surface as soon as it comes out of the earth it's lava
Why are volcanoes in our world?
They are a result of tetonic activity. they occur when two plates push together under a great pressure and then begin to fold upwards. when there is a weakness in the plates the mantles pressure builds and magma comes to the surface.
What is magma called when it comes out of the ground?
Magma that flows onto the Earth's surface is called Lava.
What happens as magma comes to the surface where plates move apart at mid-ocean ridges?
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.

Why does magma rise as the plates pull apart?
Interior pressure of the forces the magma through the crack. This upwelling of magma then rapidly cools and becomes brittle as it hardens. The pressure of the subsurface magma then breaks this brittle rock and forces more magma up in a continuous cycle.

A is an opening in Earth's surface though which magma comes out?
Fissures

How magma exit on Earth?
Under the ground (down VERY far) there are things called magma chambers. Inside them is magma (obviously). There are tubes leading out of this. When the earths tectonic plates shift the magma chamber is disturbed and magma comes up through the tubes (the tubes are naturally formed). When the magma comes up to the earth's surface it is called lava. Lava turns to a rock like substance when cool and after many "eruptions" it builds up to form what we know as volcanoes.
What is the opening in earths crust where magma comes to the surface?
The correct answer is Volcanos
Does magma shoot from a volcano or lava?
Magma is lava before it actually reaches the surface of the Earth. So magma comes from a volcano, not lava.
Magma injected into older rock?
Any molten rock that has not reached the surface is called magma. It is made when two tectonic plates collide and one edge of a plate is forced underneath the other, and pushed closer to the center of the earth where it heats up, and melts down.
