Aquatic sills are common in fjords, limiting their water exchange with the ocean.After the last ice age, approximately 18,000 years ago, continental glaciers extended to the continental shelves and created U-shaped glacial valleys, with long narrow openings that rise upward near the outer shelf, thereby creating sills.
The most dramatic orogenic belt on the planet is the one between the African plate and the Indo-Australian plate on one side (to the south) and the Eurasian plate on the other side (to the north). This belt runs from New Zealand in the east-south-east, through Indonesia , along the Himalayas , through the Middle East up to the Mediterranean in ...
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. (The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid-ocean ridge is the spreading half-rate and is equal to half of the spreading rate). Spreading rates determine if the ridge is fast, intermediate, or slow.
In more turbulent seas, frazil crystals join into flat discs known as pancakes. These slide under each other and coalesce to form floes. In the process of freezing, salt water and air are trapped between the ice crystals. Nilas may have a salinity of 12–15 ‰, but by the time the sea ice is one year old, this falls to 4–6 ‰. [33]

These are where two plates slide apart from each other. At zones of ocean-to-ocean rifting, divergent boundaries form by seafloor spreading, allowing for the formation of new ocean basin, e.g. the Mid-Atlantic Ridge and East Pacific Rise. As the ocean plate splits, the ridge forms at the spreading center, the ocean basin expands, and finally ...
A decades-long landslide has reshaped a 240-acre part of Palos Verdes Peninsula known as Portuguese Bend. Rancho Palos Verdes is mounting a plan to slow it.
Woman gets stuck on cruise's slide suspended over the ocean. A guest on a Norwegian Cruise Line ship got stuck in the closed-tubed, double-looped ride that sends sliders out over the ocean. A ...
