<span>Don't know what you mean by Earths Spheres. The Earth is a sphere -- singular. And it is made up of LOTS of matter</span>
Answer:
B
Explanation:
It is not just one of these answers, in fact they all make sense. But the one I learned in school was that when the continents were still one super continent- Pangea, animals fossilized wear the borders of modern day continents were. This later on scientists found half of an animal fossil on the edge of one continent and the other half on the edge of a different continent.
hope this helps

The concept of work-energy theorem has become much of a fundamental principle in the field of physics, mechanics, and engineering. In addition, this theory primarily states that the change of kinetic energy of the system is equal to the sum of the work done that is acted by all forces on the object.
The question is really specific enough, but I will take a guess. If nothing else changes (like the mass or the gravitational constant) then the Potential Energy will increase with an increase in height. Ep will decrease with a decrease in height.
If you are talking about Ke, then the height does not matter unless the object is moving up. Then it slows down. When that happens the Ke decreases because the formula for Ke = 1/2 m v^2. If v becomes less then Ke becomes less.
I suppose you could say if the object is going down and the distance is decreasing then the speed will increase. It's an inverse relationship.
I think you are best talking about Pe.
