Answer: C. A Chemical Change
Explanation:
A chemical change is one that occurs when new substances are produced preceding a chemical reaction ( the mixing or combination of one substance with another).

it is neutral
and may not exist independently
atom X+1
it is ion which has a charge on it positive or negative
it exists independently
B) differences in temperature
Explanation:
The factor that most directly affects the flow of ocean currents is the differences in ocean temperature from one place to another.
Ocean current is the directional movement of the ocean water in its basin.
The main cause of ocean current is differences in temperature.
- Ocean water on the surface receives direct sunlight.
- This warms and the surface and decreases their density.
- When winds blows over them, they cool and sink under their own weight.
- The less cold water in depths rise to replace them.
- This exchange of ocean water due to loss and gain of heat cause ocean current.
