Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the geological formation mechanism?Marine erosion, including hydraulic action, abrasion, and dissolution
2. What is the characteristic feature of natural grottos?Often subject to tidal inundation, creating intertidal zones
3. How do natural grottos form?Waves crash on the shore, pushing water into cracks, rubbing sand against rock, and dissolving some rocks. Over time, this makes hollows and caves.
4. Why do some grottos get flooded at high tide?Many grottos are on the coast, so when the tide goes up, water fills them, and when the tide goes down, the water leaves, exposing the cave.

Geomorphology: The study of the origin and evolution of terrestrial and ಭೂ surface features.
Hydraulic Action: The force exerted by waves and water entering cracks in rocks, compressing air.
Intertidal Zone: The area that is exposed to the air at low tide and underwater at high tide.
