The correct answer is C. Energy from the Sun breaks down rocks in the ocean, where it releases salt
The salty nature of ocean water is primarily due to the process of weathering.
Energy from the Sun causes the weathering of rocks in the ocean through processes such as erosion and chemical weathering.
This releases minerals, including salts, into the ocean water over time.
As a result, the ocean water becomes saline. Option C accurately describes this natural process.
The correct answer is C. Energy from the Sun breaks down rocks in the ocean, where it releases salt
