What causes ice jam flooding?

Rapid melting of glaciers
Broken ice blocked by an obstruction in a river
Overflow of water from ice-filled dams
High tides pushing ice onto shorelines

The correct answer is: Broken ice blocked by an obstruction in a river

Ice jam flooding occurs when broken ice blocks the flow of a river. Option A (rapid melting of glaciers) is incorrect because glaciers usually melt gradually over time and do not cause blockages in rivers. Option C (overflow of water from ice-filled dams) is also incorrect because ice jam flooding occurs in free-flowing rivers, not behind man-made dams. Option D (high tides pushing ice onto shorelines) is incorrect because high tides only affect coastal areas and not the flow of a river. Option B best explains the cause of ice jam flooding by specifically mentioning the blockage of a river due to broken ice.
