Answer:
Conglomerate rock
Explanation:
This is a type of sediment rock that has a coarse-grained texture. It is made up of small pieces of gravel-sized clasts, such as pebbles and cobbles. The mechanism of conglomerate rock formation is by consolidation and lithification.
Conglomerates are found in a variety of sedimentary environments such as, Deepwater marine, Shallow marine, Fluvial, Alluvial, and Glacial environments.
Assuming you asked a question, a land form smaller than a continent surrounded by water would be an island.
It would be the Caribbean sea! Hope this helps!
