Oceanic crust is frequently pushed into the mantle near convergent plate borders, where it starts to melt. Granite, the rock that forms the continents, is formed as magma rises into and through the other plate.
Therefore, at convergent borders, oceanic and continental crust are annihilated.
<h3>What is a diverging plate boundary?</h3>
When plates are spreading apart, new oceanic crust is being created to fill the space left behind. Most divergent boundaries are observed around mid-ocean oceanic ridges (although some are on land).
The mountains would keep eroding over the next few million years, but since there wouldn't be any tectonic activity to renew them, they would gradually erode down to low rolling hills. This would result in far less fascinating geography and a flatter planet overall.

The separation of molecules. I wouldn't put that if i were you.
Answer: the third option, each sub-level electron type has a unique path where it will likely be found.
Explanations:
1) Bhor's model of electrons orbiting the nucleus of the atom was shown to be wrong.
2) The actual model of the atom is the quantum atom model.
3) The quantum atom model depicts the electron in regions called orbitals.
4) The orbitals are the sublevels of energy (or subshells).
These sublevels (orbitals) are identified with the letters s, p, d, and f.
The orbitals s are spherical, the orbitals p are like a dumbbells, d and f orbitals have weirder shapes.
Those orbitasl are kind of electron clouds. The orbitals are defined as regions of the space around the atomic nucleus where the electrons are likely located.
Answer:
Calcium (Ca) is in group 2 and period 4 on the periodic table be because Calcium has 2 valence electrons and 4 electron shell. Thus, calcium is a metal like all other group 2 element.
