What do magnetic anomalies provide evidence of?
seafloor spreading
What is true about the thickness and age of sediments at different locations on the ocean floor that supports seafloor spreading?
Seafloor spreading is supported by the observation that sediments are thinner and younger near mid-ocean ridges, where new crust is formed, and become progressively thicker and older as one moves away from the ridge. This pattern indicates that as new oceanic crust is created at the ridge, it pushes older crust outward, allowing sediment to accumulate over time. Additionally, the age of the sediments correlates with their distance from the ridge, providing strong evidence for the continuous process of seafloor spreading.
What is one phenomenon that is considered evidence of seafloor spreading?
The Mid Atlantic Ridge
How are magnetic patterns in sea floor rock evidence of seafloor spreading?
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
What is the evidence of seafloor spreading?
Animal fossils have been found in many places in the ocean.
How are ocean-floor rocks and sediments evidence of seafloor spreading?
Ocean-floor rocks near mid-ocean ridges show a symmetrical pattern of magnetized stripes parallel to the ridge axis. These stripes result from periodic reversals in Earth's magnetic field and provide evidence of seafloor spreading. Sediments on the ocean floor also show younger ages near the ridges, supporting the idea of seafloor spreading.

Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
Ocean-floor rocks and sediments show a pattern of symmetric age distribution, with younger rocks near mid-ocean ridges and older rocks farther away. This supports the theory of seafloor spreading, where new oceanic crust is created at mid-ocean ridges and spreads away from them. As the crust moves, it picks up and records the magnetic signature of Earth's magnetic field, creating alternating magnetic stripes that are evidence of seafloor spreading.
Magnetic striping is evidence of?
pole reversals seafloor spreading
What is one phenomenon that is considered evidence of seafloor spreading?
The Mid Atlantic Ridge
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 are magnetic patterns in sea floor rock evidence of seafloor spreading?
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
How did the seafloor drilling help scientist find evidence to support the seafloor-spreading hypothesis?
people here are stupid , really the answer is not hi
How did seafloor drilling scientists find evidence to support the seafloor-spreading hypothesis?
dumb question. don't want to write it all
What is the evidence of seafloor spreading?
Animal fossils have been found in many places in the ocean.
Is there evidence that seafloor-spreading?
Yes, there is evidence supporting seafloor spreading, including magnetic striping patterns on the ocean floor, the age progression of seafloor away from mid-ocean ridges, and the presence of hydrothermal vents along mid-ocean ridges that release magma from the Earth's mantle.
