Is the analysis of seafoor sediments evidence of sea-floor spreading?
Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading
What do magnetic anomalies provide evidence of?
seafloor spreading
What are three types of seafloor spreading?
evidence from molten material evidence from magnetic stripes evidence from drilling samples
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.

Is there evidence that seafloor-spreading?
its not happy
Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches
What do magnetic anomalies provide evidence of?
seafloor spreading
How does the age of rocks in the seafloor provide evidence of seafloor spreading?
Rocks in the seafloor are moving one place to another
How are ocean-floor rocks and sediments evidence of seafloor spreading?
because that there are younger rocks found at ocean ridges than the ones found near deep-sea trenches
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.
Paleomagnetic evidence was used to confirm which of the following hypotheses?
seafloor spreading
What are three types of seafloor spreading?
evidence from molten material evidence from magnetic stripes evidence from drilling samples
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 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.
