I think it’s wind I hope I’m right
It is a matter of time. Crystallization processes can occur more easily when the rock is kept at a certain temperature during a long time. Because of that, well-formed and well crystallized minerals will appear in intrusive igneous rocks (such as granitoids). On the opposite, when a rock spreads rapidly over the Earth's surface, the temperature decreases rapidly, keeping the minerals from forming. A homogeneous paste will form, without any (or few) minerals in it. It is the case for volcanics rock
The answer is D ( Hypodermis )
Hope this helps !! :)
Process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids.
The kind of cell division that goes with growth is Mitosis. Mitosis cell division is accompanied by cellular enlargement and differentiation, so there is an increase in size and weight. I hope this helps!
