In the summer, the ridge can undergo a significant amount of weathering, which turns it into a smooth hill. During this process, the ice loses its salinity (as a result of brine drainage and meltwater flushing). This is known as an aged ridge. [9] A fully consolidated ridge is one whose base has undergone complete freezing. [9]
The Broken Ridge or Broken Plateau is an oceanic plateau in the south-eastern Indian Ocean. The Broken Ridge once formed a large igneous province (LIP) together with the Kerguelen Plateau. When Australia and Antarctica started to separate, the Broken Ridge and the Kerguelen Plateau got separated by the Southeast Indian Ridge. [1] Alkalic basalt ...
The Diamantina fracture zone (DFZ, Diamantina zone) [1] [2] [3] is an area of the south-eastern Indian Ocean seafloor, consisting of a range of ridges and trenches. [4] It lies to the south of the mideastern Indian Ocean features of the Wharton Basin and Perth Basin , and to the south west of the Naturaliste Plateau .
The state is bordered by Yukon and British Columbia, Canada to the east, the Gulf of Alaska and the Pacific Ocean to the south, Russia (Chukotka Autonomous Okrug), Bering Sea, the Bering Strait, and the Chukchi Sea to the west, and the Beaufort Sea and the Arctic Ocean to the north. Alaska's area compared to the 48 contiguous states
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering 70,560,000 km 2 (27,240,000 sq mi) or approximately 20% of the water area of Earth's surface. [4]
The Ninety East Ridge at the centre of the picture and the Chagos-Laccadive Ridge on the upper left side. The Ninety East Ridge (also rendered as Ninetyeast Ridge, 90E Ridge or 90°E Ridge) is a linear intraplate rise on the Indian Ocean floor named for its near-parallel strike along the 90th meridian at the center of the Eastern Hemisphere.
Then, they found a new volcano-like formation deep in the ocean waters. The new volcano-like structure sits more than 1,600 meters from the water's surface. So, it's far too deep to pose a danger ...
Separating the African (or Nubian–Somali plates) and Antarctic plates, the Southwest Indian Ridge (SWIR) stretches 7,700 km (4,800 mi) from the Atlantic Ocean to the Indian Ocean. With an average spreading rate of 14–15 millimetres per year (0.55–0.59 in/year), the SWIR is one of the slowest-spreading mid-ocean ridges on Earth.
