What is the floor of the ocean called?
The floor of the ocean is called the seabed or ocean floor. It is made up of different features such as abyssal plains, trenches, ridges, and volcanoes.
Are maps made from sonar and magnetometer data led to the discovery of ocean ridges and deep-sea trenches?
Yes, sonar and magnetometer data have been instrumental in the discovery of ocean ridges and deep-sea trenches. Sonar data is used to map the sea floor topography, revealing ocean ridges, while magnetometer data helps identify variations in the Earth's magnetic field caused by stripes of rock on the ocean floor, contributing to understanding plate tectonics and the formation of deep-sea trenches.
How is the formation of mid-ocean ridges and trenches different?
Mid-ocean ridges form at divergent boundaries where tectonic plates are moving apart, allowing magma to rise from the mantle and create new oceanic crust. Trenches form at convergent boundaries where one plate subducts beneath another, creating deep oceanic trenches due to the sinking of the denser plate back into the mantle.
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
What are valleys between the ridges on the ocean floor?
They are called oceanic trenches.
What is the connection between high temperatures measured at ocean ridges and the formation of basalt ridges?
realate the high tempertures measured at the mid-ocean to the formation of basalt at the ridges
Compared to ocean crust near deep-sea trenches crust near ocean ridges are?
Compared to ocean crust near deep-sea trenches, crust near ocean ridges is generally younger, thinner, and hotter. Ocean ridges are sites of active seafloor spreading where magma rises to create new crust, while deep-sea trenches are associated with subduction, where older, denser crust is pulled back into the mantle. As a result, the crust at ocean ridges is also less dense and more buoyant than the crust found near trenches.
Compared to ocean crust near deep sea trenches crust near ocean ridges is?
Compared to ocean crust near deep sea trenches, crust near ocean ridges is generally younger, thinner, and hotter. Ocean ridges are sites of seafloor spreading where magma rises to create new crust, leading to the formation of younger geological features. In contrast, ocean crust near deep sea trenches is older, denser, and often subjected to subduction, where it is pushed back into the mantle. This results in more complex geology and greater age in trench-adjacent crust.
What physical feature occures along ocean trenches and ridges?
The physical feature that occurs along ocean trenches and ridges is seafloor spreading. This process is when new oceanic crust is formed at mid-ocean ridges through volcanic activity, pushing the older crust away from the ridge towards ocean trenches where it is eventually subducted back into the mantle.
How do you contrast mid-ocean ridges and trenches?
Mid-ocean ridges are the birthplace of oceanic crust. Trenches represent the destruction and burial of oceanic crust. They are at opposite ends of the Earth's convection currents that move through the asthenosphere.
What are 2 geological features that can occur at plate boundaries?
Two geological features that can occur at plate boundaries are mountain ranges, formed from the collision of two plates, and deep ocean trenches, formed at subduction zones where one plate is forced beneath another.
Which part of the ocean is the deepest ridges seamounts rifts or trenches?
The deepest parts of the ocean are found in trenches. Trenches are narrow, steep-sided depressions in the ocean floor, with the Mariana Trench being the deepest known point on Earth. While seamounts and ridges are underwater mountains and elevated areas, respectively, they do not reach the extreme depths characteristic of oceanic trenches. Rifts, on the other hand, are areas where tectonic plates are pulling apart, often associated with mid-ocean ridges but not typically the deepest locations in the ocean.
