What is an underwater mountain range?
Undersea mountain range. Mountain ranges that are mostly or entirely under the surface of an ocean. Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge.
What is the largest mountain range in the world?
The largest and best known undersea mountain range is a mid-ocean ridge, the Mid-Atlantic Ridge . It has been observed that, "similar to those on land, the undersea mountain ranges are the loci of frequent volcanic and earthquake activity".

How long is the Transantarctic Mountains?
The Transantarctic Mountains transverse through ice and glaciers to divide the Antarctic continent into east and west. It Stretches 3,542 km (2,200 miles) long with 98% of this covered by the ice making it largely inaccessible.
How long is the Mid Ocean Ridge?
The global Mid-Ocean Ridge is the longest of the sub-marine mountain ranges, stretching for a length of about 65,000 km (40,000 miles). Sub-marine mountain ranges, also a product of plate tectonics are found underwater. The mountains are formed from cooled lava after the sea floor is forced to rise from convection currents.
What is the highest mountain in the Australian Alps?
The Australian Alps, a section of the range contains the highest peak, Mouth Kosciuszko rising 2,228 meters (7309.71ft) above sea level. The range includes some rivers such as the Snowy River and the Goulburn River. These rivers have facilitated agriculture across the chain through irrigation.
What is the highest mountain in Queen Maud?
The highest peak is Mount Kirkpatrick at 4,528 m (14,855.6 ft) in Queen Maud. Research carried out on the range uncovered fossils of plants and reptiles which suggested that the ranges may have been hospitable before. The Range is home to large numbers of seals, penguins, and flying seabirds.
How far are the Rocky Mountains?
The Rocky Mountains (Rockies) is a spectacular range of peaks and valleys stretching for about 4,800 km (3,000 miles) from northern British Columbia in Canada down south to New Mexico in the United States.
How deep is the mid ocean ridge?
The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).
What is the mid ocean ridge system?
The nearly continuous, global mid-ocean ridge system snakes across the Earth’s surface like the seams on a baseball. It is clearly visible on this map of global topography above and below sea level. The ridge system forms the longest and largest mountain range on Earth, winding its way between the continents. Download image (jpg, 123 KB).
What causes mid ocean ridges?
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. The speed of spreading affects the shape of a ridge – slower spreading rates result in steep, ...
How fast does the Mid Atlantic Ridge spread?
The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean, slowly spreading at a rate of 2 to 5 centimeters (0.8 to 2 inches) per year and forming a rift valley that is about the depth and width of the Grand Canyon. In contrast, the East Pacific Rise spreads fast, at rates of 6 to 16 centimeters (3 to 6 inches) per year.
How fast does the East Pacific Rise spread?
In contrast, the East Pacific Rise spreads fast, at rates of 6 to 16 centimeters (3 to 6 inches) per year. Due to the fast spreading rates, there is no rift valley in the Pacific, just a smooth volcanic summit with a crack along the crest that is much smaller than the Atlantic rift valley.
What is the NOAA Office of Ocean Exploration and Research?
By funding expeditions to spreading centers in the Atlantic and the Pacific, the NOAA Office of Ocean Exploration and Research is helping scientists to draw connections between volcanic, tectonic, hydrothermal, and biological systems in order to better understand the Earth’s remarkable, evolving geography.
What are the mountains in the deep sea?
The Mountains of the Deep Sea. Entire mountains and mountain ranges lay submerged beneath the surface of our oceans. These underwater mountains, called seamounts rise thousands of feet from the sea floor, and stand waiting, as they have for millions of years, to be explored. Nobody paid much attention to these seamounts before ...
How high are seamounts?
Seamounts are technically defined by oceanographers as conical in form and rising to at least 1,000 meters (3,281 ft) above the sea floor. Many of them are actually extinct volcanoes.
What are some examples of seamounts?
Seamounts are as diverse in shape and size as they are numerous – each harboring its own story of formation. For example, a guyot is a seamount with a flat top. Over the course of its formation over millions of years, it breaches the surface.
Why are seamounts important to the ecosystem?
Because of the way that seamounts influence currents, they often are areas of nutrient upwelling – supporting a productive and diverse ecosystem. This is why they are so often targeted by fishermen, as many of them support extensive fisheries.
Why is Muirsfield Seamount named Muirsfield Seamount?
Muirsfield Seamount is named after the ship that struck it, sustaining heavy damage to the keel. However, the most likely threat that seamounts pose is when, due to instability from old age, their sides and flanks slough off causing an undersea landslide which has the potential to trigger a massive tsunami.
How many species of fish are targeted on seamounts?
Nearly 80 species of fish are targeted on seamounts, but when the bottom is trawled, the whole ecosystem is destroyed. When we demand unsustainable seafood, commercial fisheries are inclined to fish wherever and however they can with no regard to long-term fisheries stocks.
Can submersibles be used to explore seamounts?
Submersibles (manned and unmanned) can also be used to explore seamounts, once they have been located. They can record observations, gather measurements and collect chemical/geological/biological samples, allowing us to put eyes and (robotic) hands at great depths – depths much greater than a human diver could go.
What are the geologic features of the ocean floor?
There are many geologic features on the ocean floor. Trenches, ridges, rises, and islands are the result of continental or oceanic plate movement. Volcanic eruptions and earthquakes are also the result of tectonic plate movement. Prior Knowledge.
What is trench in geology?
Define on a whiteboard the terms below, creating a key using a different color to represent each term. A trench is a long, deep depression in the ocean floor.
What is a gap in geography?
A gap is a steep-sided opening through a mountain ridge. A seamount is an underwater mountain. A rise is an underwater mountain range located where tectonic plates are spreading apart. A rise is also known as a mid-ocean ridge. A plateau is a large region that is higher than the surrounding area and relatively flat. 2.
