🌍The Earth's land and sea are not separate; land extends beneath the oceans.
🌋Volcanic activity creates new landforms, such as islands and mountains, in the middle of nowhere.
🗾Continents tearing themselves apart leave behind fragments, forming new landmasses.
🌊Sea levels are dictated by ancient happenstance, such as asteroid impacts.
🔥Hotspots and magma discharge shape the underwater geography of the Pacific and Indian Oceans.
How are continents formed?
—Continents are formed through various processes, including volcanic activity, tectonic plate movements, and the accumulation of sediments.
Why are some landmasses submerged?
—Landmasses can become submerged due to tectonic movements, sea level changes, or the erosion of land over time.
What determines the size and shape of islands?
—The size and shape of islands are influenced by volcanic activity, erosion, and the interaction between tectonic plates.
Are there still undiscovered landmasses in the oceans?
—It is possible that there are undiscovered landmasses in the oceans, as our knowledge of the Earth's underwater geography is still expanding.
How do hotspots contribute to land formation?
—Hotspots are areas where magma from deep within the Earth rises to the surface, creating volcanic activity that can lead to the formation of new landmasses.
