What is happening to the floor of the Atlantic ocean due to movement of the plates under the ocean?
The floor of the Atlantic Ocean is spreading apart as the tectonic plates beneath it move away from each other. This process, known as seafloor spreading, results in the creation of new oceanic crust along mid-ocean ridges. As the plates move apart, magma rises from the mantle to fill in the gap, solidifying into new crust and pushing the existing crust away.
Which observation about mid Atlantic ridge region provides the best evidence that the sea floor has been spreading for millions of years?
The best evidence for sea floor spreading at the Mid-Atlantic Ridge is the symmetrical pattern of magnetic anomalies on either side of the ridge. These anomalies record reversals in Earth's magnetic field, with alternating strips of normal and reversed polarity. As new crust is formed at the ridge and older crust is pushed away, the age of the rocks increases with distance from the ridge, demonstrating continuous and symmetrical sea floor spreading over millions of years. This geological pattern supports the theory of plate tectonics and the dynamic nature of the Earth's crust.
How does the Mid Atlantic Ridge affect the Atlantic Ocean?
The Mid Atlantic Ridge is a divergent boundary where tectonic plates are moving apart, causing magma to rise and create new oceanic crust. This process influences the ocean floor topography, creating a ridge system that stretches through the Atlantic Ocean. The ridge also impacts ocean circulation patterns, biodiversity, and plays a role in the formation of hydrothermal vents.
Why are the rocks in they centre of Atlantic ocean floor younger than the rocks found on the eastern or western areas of the Atlantic ocean?
The rocks in the center of the Atlantic Ocean floor are younger because they are formed at mid-ocean ridges through volcanic activity, where tectonic plates are diverging. As magma rises and solidifies at these ridges, it creates new oceanic crust. In contrast, rocks found on the eastern and western margins of the Atlantic Ocean have been subjected to processes such as subduction and erosion, making them older. This process of seafloor spreading continually pushes older rocks away from the ridge, resulting in a younger ocean floor at the center.
Where were the older rocks on the sea floor found?
The oldest layers of sea floor would exist at the bottom of the Marianas Trench, where oceanic plate subduction is occurring. The subducting oceanic plate is less than 200 million years in age.
What is the floor of the Atlantic ocean called?
North Atlantic Oscillation
What prominent sea floor feature is found in the central Atlantic ocean?
The prominent sea floor feature found in the central Atlantic ocean is called the Mid Atlantic Ridge.
What happens at the mid-atlantic ridge?
Sea floor spreading
Why is the earth's surface not expanding?
This is because when one divergent boundary is occurring (more sea floor being made), convergent boundaries are occurring (the sea floor is being consumed) on the other sides of the plates, such as what is occurring at the Mariannas Trench in the Pacific Ocean.
What is the result of an earthquake occurring on the ocean floor?
tsunami's would occur
Was th titanic found on the Atlantic ocean floor?
yes
What sea floor did marlin whet in finding nemo?
Atlantic
What is the mountain range rising above the ocean floor of the Atlantic ocean is known as the?
That would be the Mid-Atlantic Ridge.
Why is the Atlantic Ocean is spreading?
The oceanic crust of the Atlantic Ocean floor is attached to the continental crust of the continents around the ocean. So as the Atlantic's Ocean floor spreads, the continents along its edges also move. Over time, the whole ocean gets wider.
