Answer: Tissue.
Molecules make up cells, cells make up tissue, tissue makes up organs, organs make up organ systems.
It would be rock by erosion bc the rocks erode to form a volcano
To solve the problem it is necessary to apply energy conservation.
By definition we know that kinetic energy is equal to potential energy, therefore
PE = KE
Where,
m = mass
g = gravitaty constat
v = velocity
h = height
Re-arrange to find h,
Replacing with our values
Therefore the correct answer is C.
