Is it true as magma cools it's atoms tend to move away from each other?

The slower the rate of cooling the larger the size of the crystals that can develop.

So rocks that cool down quickly have smaller crystals (or grain) than those that cool down more slowly, which gives the crystals a longer period in which to grow.

How do atoms unite with other atoms?
Atoms with the same charge are pushed away from each other. Atoms with different charge attract (unite)
What is the mid-atlantic ridge made of?
As the two tectonic plates on either side of each side of the ridge pull away from each other the ground weakens and eventually boiling rock/magma pushes up like an underwater volcano. This volcano dosent have much force though. This magma quickly cools forming new land, like the Giants Causeway in Northern Ireland.In short Melted rocks that have cooled
Why are a molecule atoms as far away from each other as they can get?
The negative charges of their electrons repel each other.
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.
A vent at the earth's surface through which magma and gases erupt?
Magma becomes known as lava when it reaches the surface. And when the lava cools it usually forms some type of igneous rock, depending on the chemical composition of the lava. The gases have no common name that I know of. But for the most part they are common gases which include but are not limited to steam, CO2, and traces of sulfur gases.
What creates new crust as plates move away from each other?
Magma rises up from the earth's mantle and cools to create new crust.
Hot fast moving lava?
The center of the earth is the hottest, and the crust is the furthest away from that heat.
Where is the only significant land surface on which new crust is being created by rifting?
Divergent plate boundaries. They pull away from each other, and magma rises from the gap, cools, and solidifies, which creates "new" crust.
Does magma cause plate techtonics?
Yes. Following the idea that heat rises, the magma rise from the core to the mantle, where it then cool down, this causes it to fall, however, it falls outwards, this cause the plates to push away from each other, but if they fall into each other, the plate's are pushed into one another. This is how volcano's are made, as the magma seeps though the Earth's crust and cools, forming rock. Hope this has helped.

What happens to magma after it erupts onto the ocean floor?
The magma spills over the ridge and pushes the old sea floor away toward a subduction zone where the old sea floor melts.
How does igneous rocks form?
Igneous rocks forms when molten rock cools&becomes solid. Igneous rocks that originally formed at great depths can reach Earth's surface over time. Deep rocks may be raised closer to the surface when mountains are pushed up.At the same time , other process can wear away the rocks that cover the deeper rocks
Why do volcanoes go extinct?
There are a number of causes. In some cases the magma beneath a volcano cools until it is too viscous to erupt, and can even solidify completely if given enough time. A new injection of magma from the mantle can cause activity to resume. Sometimes the ultimate source of magma is removed as the plate moves away from a hot spot, or is consumer by subduction.
Why does the hydrogen atom keep itself as far away from other atoms?
because the hydrogen atom smells and the other atoms make fun of it
Why are molecule atoms are far away from each other as they can get?
Forces between electron pairs push the atoms apart.
