What is the difference between guyots and seamounts?
Seamounts and Guyots are volcanoes that have built up from the ocean floor, sometimes to sea level or above. Guyots are seamounts that have built above sea level. Erosion by waves destroyed the top of the seamount resulting in a flattened shape. A seamount never reaches the surface so it maintains a “volcanic” shape. .
How are seamounts and Tablemounts similar?
The main difference between seamounts and tablemounts is that tablemounts are flat on top, whereas seamounts have pointy (peaked) tops.
What are seamounts and guyots use their definitions to communicate how they relate to one another?
Seamounts are submerged volcanic mountains that are taller than 1 km. Seamounts that rise above the water form oceanic islands. Guyots are different from seamounts. Guyots are when seamounts are eroded, and form flat-topped submerged seamounts. A continental shelf is the part of the continent that is covered by water.
Where are seamounts located?
mid-ocean ridges
Seamounts are commonly found near the boundaries of Earth’s tectonic plates and mid-plate near hotspots. At mid-ocean ridges, plates are spreading apart and magma rises to fill the gaps.
What is the origin of seamounts Guyots and atolls?
Most seamounts are volcanic in origin, and thus tend to be found on oceanic crust near mid-ocean ridges, mantle plumes, and island arcs. Overall, seamount and guyot coverage is greatest as a proportion of seafloor area in the North Pacific Ocean, equal to 4.39% of that ocean region.
How are seamounts and islands similar?
Both of them are formed by volcanoes? How are seamounts and islands similar? The rock structure of the ocean floor has dense basalt rock, whereas continents have a less denser form of rock called granite. What is the difference in rock structure between the ocean floor and the continents?
What is the relationship between the crust and lithosphere?
Explain the difference between the crust and the lithosphere. The crust is the thin, outermost layer of the Earth that is composed differently than the mantle. The lithosphere is a thick layer that contains both the crust and the upper mantle (which is rigid compared to the underlying asthenosphere).
Where are seamounts usually found?
Seamounts are commonly found near the boundaries of Earth’s tectonic plates and mid-plate near hotspots. At mid-ocean ridges, plates are spreading apart and magma rises to fill the gaps.
