What are Mountains on the ocean floor that turn into volcanic islands called?
Mountains on the ocean floor that rise above sea level and form volcanic islands are called seamounts. These seamounts are formed by volcanic activity and can eventually emerge from the water to become volcanic islands.
What geologic features of the ocean floor do you think are formed by crustal plates moving together?
Ocean trenches, volcanic arcs, and island arcs are examples of geologic features on the ocean floor formed by crustal plates moving together. Subduction zones are common in these areas, where one plate is forced beneath another, creating deep ocean trenches and leading to volcanic activity along the plate boundaries. Island arcs can also form as a result of subduction, with chains of volcanic islands aligning parallel to the trenches.
Is stalactite a deposit of calcite on a cave floor?
No, a stalactite is a mineral formation that hangs from the ceiling of a cave, formed by the dripping of mineral-rich water. It is made of minerals such as calcite, but it forms on the ceiling, not the floor.
What is an undersea volcanic formation that does not rise at least 1000 meters above the surrounding sea floor is called?
An undersea volcanic formation that does not rise at least 1000 meters above the surrounding sea floor is called a seamount. These underwater mountains are formed by volcanic activity and can vary in size and shape.
A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called?
That is a description of a trench, which is formed at tectonic plate boundaries where one plate is forced beneath another through a process called subduction. Trenches are among the deepest parts of the ocean floor.
What makes up the far western region of North America which formed by accretion?
Many terranes, including island arcs, submarine deposits, and ancient ocean floor
What island was formed by sea-floor spreading?
Iceland is an example of an island formed by sea-floor spreading. It sits on the Mid-Atlantic Ridge, where the Eurasian and North American tectonic plates are diverging. As these plates pull apart, magma rises from the mantle to create new oceanic crust, resulting in the formation of the island. This geological activity also leads to volcanic eruptions, contributing to Iceland's unique landscape.
What is the reason for the formation of the Hawaii island?
The Hawaiian Islands (there is more than one of them) were formed from the eruption of volcanos on the floor of the ocean. We see the part that sticks up above the water. The next island is being formed underwater to the southeast of the Big Island, is still 3000 feet underwater, and is named the Lo'ihi Seamount.
Where is petroleum formed?
Petroleum is formed from the remains of ancient marine organisms that accumulated on the ocean floor over millions of years. These organic materials were subjected to high heat and pressure underground, leading to the formation of petroleum.
Mineral-rich water heated by newly formed oceanic crust escapes through cracks in the ocean floor called?
Th water escapes through cracks in the ocean floor called hydrothermal vents.
What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
Where did you probably find a deposit of limestone what type of setting did it form in?
Limestone is formed on the floor of ancient seas from the skeletal remains of marine organisms such as coral, forams and molluscs, etc.
The cross-shaped floor plan of a church is formed by the combined shapes of the nave and the?
It is called the cruciform. It is the combined shapes of the nave and transepts.
What causes the initial creation of the island?
Islands can be formed through volcanic activity, where lava erupts from the ocean floor and accumulates over time to form landmasses. They can also be formed through sedimentation, where sand, rocks, and debris accumulate in a specific area, creating an island. Other factors like tectonic plate movements and erosion can also play a role in island formation.
What Island are most likely to have active volcanoes Why?
Hawaii Hawaii was formed from a volcano that grew from deep on the ocean's floor. If it was on land it would be several times higher than the tallest mountain.
As new sea floor is formed high spots are formed what are they called?
High spots formed as new seafloor is created are known as seamounts or underwater mountains. These features are often formed by volcanic activity or tectonic movement along mid-ocean ridges. Seamounts can vary in size and shape, with some rising thousands of feet from the ocean floor.
What are Mountains on the ocean floor that turn into volcanic islands called?
Mountains on the ocean floor that rise above sea level and form volcanic islands are called seamounts. These seamounts are formed by volcanic activity and can eventually emerge from the water to become volcanic islands.
