Which thermal profile develops during Antarctic Bottom Water formation?

💡 Explanation

Surface water cooling causes brine rejection because salt is excluded during ice formation, increasing the density of surrounding waters; this Density-Driven Circulation then sinks to form Antarctic Bottom Water. Therefore, A is correct rather than destabilization from geothermal vents, surface mixing, or stratification.

• Which feedback occurs when coastal upwelling of nutrient-rich water causes a phytoplankton bloom that decreases surface albedo?
• Which landscape outcome occurs with prolonged katabatic wind erosion?
• Which climatic response increases when weakened trade winds reduce upwelling during an El Niño event?
• Which topographic feature is primarily formed by the mechanism of solifluction in periglacial environments?
• Which outcome occurs when excessive discharge flows into an alluvial river system lacking fully developed levees?
• Which outcome occurs when decreased river competence deposits oversized alluvial components?
