Where do midocean ridges intersect the landmasses?
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
Is the Mid-Oceanic Ridge in the middle of the Atlantic Ocean?
One of the midocean ridges is, but others are in other oceans, seas, and bays.
Do Ocean sediments become younger or older away from midocean ridges?
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
Is the mid-Atlantic ridge getting smaller or larger?
The Mid-Atlantic Ridge is in a constant process of growing at the boundary and shrinking as it moves away from the boundary. Therefore, on a year to year basis, it is both getting larger and smaller. In geologic time, however, it will start shrinking when the continents it is moving can no longer be moved toward each other due to collisions caused by plate tectonics
Which two tectonic plates are separated by the midocean ridge?
The mid ocean ridge separates many plates, not just two. In the Atlantic Ocean it separates the Eurasian and African plates from the North American Plate and the African Plate from the South American Plate. In the Indian Ocean it separates the African Plate from the Antarctic, Australian, Indian Plates and the Australian Plate from the Antarctic Plate. In the Red Sea it separates the African Plate from the Arabian Plate. In the Pacific Ocean it separates the Pacific Plate from the Antarctic, Nazca, Cocos, and Juan de Fuca Plates and the Nazca Plate from the Cocos and Antarctic Plates.
What are the differences between ocean ridge and seamount?
The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.
What is a force that is causing the plates to move at a midocean ridge?
friction - convection currents in the mantle drag the plates away from the hot rising zone below the ridgegravity - gravity pulls down on the cold dense plate being subducted under the continent, dragging the plate away from the ridge
Were the Blue Ridge Mountains once larger then Everest?
No, the Blue Ridge Mountains were never larger than Mount Everest. The Blue Ridge Mountains were formed over 1 billion years ago and have eroded significantly over time, while Mount Everest, part of the Himalayas, was formed much more recently through tectonic plate collisions and continues to rise. At their peak, the Blue Ridge Mountains were likely taller than they are today, but they never reached the heights of Mount Everest, which stands at 29,029 feet (8,848 meters).
Is the mid Atlantic ridge getting smaller or larger?
it is getting larger because the plates are sliding transparently and they move against their sides not one on top of the other. im 14 and i just learned this in science class a week ago :)
When was the blue ridge mountain formed?
The Blue Ridge Mountains are part of the larger Appalachian Mountains range.
The movement of the ocean floor on either side of a midocean ridge is best known as?
it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.
What is smaller than the blue ridge parkway?
donvalley parkway
