Question

1. where are most of the cold currents found?
2. the flow of water around our planet is ultimately caused by:

sinking dense water
rising salty water
sinking warm water

Explanation:

For question 9: Ocean cold currents typically form near polar regions and move along the western coasts of continents in the lower latitudes, and are concentrated in the higher (polar) latitudes and eastern sides of ocean basins overall.
For question 10: The global ocean conveyor belt (planetary water flow) is driven by density differences; dense water (cold, salty) sinks, which pulls water through the global ocean system. The other options are incorrect: salty water does not drive the flow by rising, and warm water is less dense so it does not sink to drive the flow.

Answer:

1. Most cold currents are found along the western coasts of continents in tropical and subtropical regions, and in the high-latitude (polar) areas of the world's oceans.
2. sinking dense water
