piles of basaltic lava flows built up from the ocean floor by multiple, summit and flank eruptions
just cuz
Oceanic crust is generally thinner, denser, and primarily composed of basalt, while continental crust is thicker, less dense, and mostly made of granite. These differences result in oceanic crust sinking lower into the mantle, forming ocean basins, whereas the buoyant continental crust rises to create landmasses. Additionally, tectonic processes, such as subduction and rifting, further shape the distribution of ocean basins and continents over geological time.
The word 'pacific' (lower case p) is an adjective, a word that describes a noun as conducive to peace, not aggressive (a pacific nation, pacific people, etc.).The word 'Pacific' (capital P) is a proper noun , the name of a specific ocean, the "Pacific Ocean".The word 'Pacific' (capital P) is also a proper adjective, a word that describes a noun as of or related to the Pacific Ocean (Pacific islands, Pacific fleet, etc.).
Indonesia is located between the Indian Ocean and the Pacific Ocean. The islands of Indonesia are located along the equator between Asia and Australia.
Nobody knows , it was over Ocean with a few small islands.
Mountains on the ocean floor that rise above sea level and form volcanic islands are called seamounts. These seamounts are formed by volcanic activity and can eventually emerge from the water to become volcanic islands.
Undersea volcanoes, also known as seamounts or submarine volcanoes, can be found along mid-ocean ridges, convergent plate boundaries, and hotspots. These volcanic structures are typically located in ocean basins and can sometimes rise above the water surface, forming islands.
Most seamounts are located in the Pacific Ocean, particularly in regions like the Hawaiian Islands, the western Pacific, and the northwestern Pacific. These areas have extensive volcanic activity and tectonic plate movements that contribute to the formation of seamounts.
Seamounts are underwater mountains formed by volcanic activity, typically found on ocean floors. They can be located in various ocean basins around the world, often rising from the seafloor but not reaching the surface. Common regions where seamounts are found include the Pacific Ocean, the Atlantic Ocean, and near mid-ocean ridges. They often serve as important habitats for marine life and can influence local ecosystems.
The Pacific Ocean has many small scattered islands that were formed from the tips of extinct volcanoes. These types of islands are known as volcanic islands or seamounts and can be found throughout the Pacific's vast expanse.
Yes, seamounts are underwater mountains that rise from the ocean floor but do not reach the water's surface. The tops of seamounts are typically submerged beneath the surface of the ocean.
Isolated volcanic peaks on the ocean floor are known as seamounts. The deepest parts of the ocean are long, narrow features known as deep ocean trenches.
Examples of landforms that rise above the ocean floor include islands, seamounts, and ridges. Islands are areas of land completely surrounded by water, while seamounts are underwater mountains that peak above the ocean floor. Ridges are long, elevated areas that can stretch for thousands of kilometers along the ocean floor.
Ocean basins are not completely flat; they feature a variety of geological structures, including mountains, valleys, and trenches. While the abyssal plains, which make up a significant portion of ocean basins, appear relatively flat and smooth, other features like mid-ocean ridges, seamounts, and deep-sea trenches contribute to a more complex topography. Overall, the ocean floor is characterized by a diverse range of landscapes, contrary to the notion that it is just a flat plain.

The oldest features on the ocean floor are typically oceanic crust and some continental fragments that date back to the formation of the Earth’s lithosphere. However, specific geological formations like ancient seamounts or guyots, which can be remnants of volcanic activity, are often older than the surrounding ocean basins. Additionally, some continental shelf areas may contain older sedimentary rock layers that predate the current oceanic crust. Overall, while the ocean basins themselves are relatively young in geological terms, certain features and formations can be significantly older.
