Answer:
False
Explanation:
It is true that new crust is being created at the mid-oceanic ridges, but this does not make the Earth any bigger despite the the growth of oceanic crusts in these regions.
The reason that Earth does not get bigger is because the same plates that are being created at the divergent plate boundaries are recycled into the mantle at the subduction zones. Because of this, the surface area of the Earth remains the same.
Answer:
electron cloud charge of manganese=-5
Explanation:
atomic number=number of elecron +neutron number
DATA
Neutron NO.=30
atomic NO.=25
e=?
A=e+n
25=e+30
e=25-30
e= -5
The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance or object.
In a chemical equation, a subscript tells one how many atoms or molecules of a reactant or a product take part in a reaction.
There are two scales, one is a Ritcher scale and another one is called a Mercalli scale.
