The image below shows a close-up of the crystals formed in a pegmatitic rock. Which characteristic provides the best evidence that is rock solidified deep underground?
Option C (very coarse texture) is the appropriate one.
Explanation:
Everything always cools quickly because once magma reinforces above that of the ocean floor and perhaps the shape it possesses seems to be agricultural context, color temperature, and so on. But as magma settles down underneath the layer, it gets sufficiently opportunity to solidify, culminating in a much more gritty texture as well as color change, respectively.
We then assume that perhaps the assumption of whether concrete solidified buried underground correlates to a rather coarse framework.
Other decisions aren't linked to the circumstance issued. So the one above is indeed the best one.
