What else can I help you with?
Is it true that as the new seafloor moves away from the ridge and becomes hotter it moves upward and forms still higher ridges?
Yes, it is true. As the new seafloor forms at mid-ocean ridges and moves away, it cools and becomes denser. The denser seafloor sinks lower, creating space for more magma to rise at the ridge, forming still higher ridges.
How did harry hess hypothesis explain seafloor movement?
Harry hess' hypothesis was hot/less dense material rises up the Earth's crust toward the mid-ocean ridges. When the seafloor breaks apart, magma is forced upward and through the cracks. It cools, and becomes a new seafloor. When it moves away from the mid-ocean ridge, it becomes denser and sinks. This helps form ridges.
How do the ages of the rocks on the seafloor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
How does the age of seafloor sediments change with increasing distance from the ocean ridge?
Age of seafloor rock and sediment increases with distance from the oceanic ridges.
Where is the place where seafloor spreading occur?
Mid-oceanic ridges
What is the place that new seafloor is created?
in mid ocean ridges
How does the age of rocks in the seafloor provide evidence of seafloor spreading?
The age of rocks gets progressively younger as you move away from the mid-ocean ridges, where seafloor spreading occurs. This supports the theory of seafloor spreading, as new crust is being formed at the ridges and then moves away from them over time. This process leaves a record of older rocks further from the ridges and younger rocks closer to them.
At which type of plate boundary is the youngest seafloor located?
The youngest seafloor is located at mid-ocean ridges, which are divergent plate boundaries where tectonic plates move apart. As new oceanic crust is formed through seafloor spreading, it pushes older crust away from the ridge, making the seafloor at mid-ocean ridges the youngest on Earth.
Where do seafloor hot springs occur?
Along the mid oceanic ridges.
What do isochron maps of the seafloor indicate?
oldest near ocean ridges
Where are most seafloor spreading centers located?
It is the mid-ocean ridges.
What process forms new seafloor?
New seafloor is formed through a process called seafloor spreading, which occurs at mid-ocean ridges. Magma rises from the mantle and solidifies to create new crust as tectonic plates move apart. This continuous process results in the creation of new seafloor and plays a key role in plate tectonics.
