Which of the following are features of the ocean conveyor belt? Select all that apply.
|
|
high salinity and low temperature of surface water near the North Pole
|
|
|
Gulf Stream current carrying cold water from Florida up through and across the North Atlantic Ocean toward Europe
|
|
|
upwelling bringing nutrients from the deep sea up toward the surface near landmasses such as Antarctica
|
|
|
undersea volcanic activity heating large amounts of ocean water, causing it to rise to the surface
|
Explanation:
Detailed explanation-1: -The global ocean conveyor belt is a constantly moving system of deep-ocean circulation driven by temperature and salinity.
Detailed explanation-2: -Ocean circulation can be conceptually divided into two main components: a fast and energetic wind-driven surface circulation, and a slow and large density-driven circulation which dominates the deep sea. Wind-driven circulation is by far the most dynamic.
Detailed explanation-3: -The conveyor belt is also a vital component of the global ocean nutrient and carbon dioxide cycles. Warm surface waters are depleted of nutrients and carbon dioxide, but they are enriched again as they travel through the conveyor belt as deep or bottom layers.
