Question 4911 Deck General
70% to passWhen operating in an area where sea ice and icebergs are present, which statement is TRUE?
A
Both icebergs and sea ice will move in approximately the same direction and at the same speed.
B
Icebergs and sea ice will move in the same direction, but at different speeds due to the sail effect of the berg.
C
Icebergs and sea ice will move in the same direction, but the iceberg will move slower because of its underwater bulk.
D
Icebergs may travel in a direction many degrees different from the sea ice.
AI Explanation
The correct answer is D) Icebergs may travel in a direction many degrees different from the sea ice. This is because icebergs are primarily influenced by ocean currents, which can differ significantly in direction from the wind-driven movement of sea ice. The underwater bulk of an iceberg allows it to be affected more by subsurface currents, which can cause the iceberg to drift in a different direction than the surrounding sea ice on the surface. In contrast, the other options assume the iceberg and sea ice will move in the same general direction, which is not always the case due to this difference in driving forces.
