Chemistry

Answer:

The answer is: B

Explanation:

The reason for this is because when a rock is underwater (the river, in this case), the water runs across it non-stop until the rock is removed from the water. The only way it can be polished if it is submerged under the water for quite some time (years and years).

I hope this helped! :))

Answer:

The answer is B.  A river is a body of water, therefore, there will always be some water running over the rock.

Only one: the nucleus of an atom is made up of protons and neutrons.
Why others are false:
Boiling point of a substance is not dependent on the volume because it’s a intensive property.
During sublimation, a solid changes directly into gas.
Electrons orbit the nucleus of an atom in circular orbits (kinda unsure of this one.)
