Which of the following would cause sea level to fall?
A) a decrease in the amount of glaciers on land
B) a slowing in the rate of seafloor spreading
C) a rise in the temperature of the oceans
D) all of these
Seafloor Spreading
The process by which new oceanic crust is created at mid-ocean ridges as tectonic plates diverge, leading to the gradual widening of an ocean basin.
Glaciers
Slow-moving rivers of ice formed by the accumulation and compaction of snow on mountains or near poles, which shape the land through erosion.
Sea Level
The average height of the ocean's surface between the high and low tide, used as a standard in reckoning land elevation or sea depths.
- Acknowledge the determinants impacting alterations in sea levels.
- Comprehend the function of seafloor spreading within marine processes.

Final Answer :
B
Explanation :
A slowing in the rate of seafloor spreading would cause sea level to fall because it would reduce the volume of the mid-ocean ridges, allowing more water to be accommodated in the ocean basins. Decreasing glaciers (A) and rising ocean temperatures (C) would both contribute to sea level rise, not fall.
