Final answer:
True statements about salt water are that it contains various minerals, objects float more easily in it than in fresh water, and both the depth of the water and the ocean's location affect its temperature.
Step-by-step explanation:
The properties of salt water are essential to understanding both chemistry and earth sciences. To clarify the presented statements:
- Indeed, objects float more easily in oceans than in lakes or rivers due to the higher density of sea water.
- The temperature of ocean water is also affected by the ocean's location, impacting climate and weather patterns.
