What Happens to a Sea Arch Over Long Periods of Time?
What will happen to a sea arch over long periods of time?
A. The hole in the sea arch will become smaller, and new rock will form inside the hole.
B. The hole in the sea arch may become larger or smaller depending on the rock layers.
C. The hole in the sea arch will stay the same, and the arch will remain in place.
D. The hole in the sea arch will become larger, and the arch will eventually collapse.
Answer:
Over long periods of time, the hole in the sea arch will become larger, and the arch will eventually collapse. Therefore, the correct option is option D.
Explanation:
Over long periods of time, the constant erosion and weathering by wind and waves will weaken the rock layers that make up the sea arch. These forces cause the rock material to weaken, which enlarges the hole and reduces the overall structural stability of the arch.
As the hole in the sea arch becomes larger, the weight of the rock above it becomes unsupported and unstable. Eventually, the arch will collapse due to the force of gravity. This is a natural process of erosion and formation that occurs in many coastal areas around the world.
Hence, the correct answer is option D.
