Earth's what field are recorded by rocks in strips parallel to ridges?
earth's magnetic feild
How do strip of magnetized rock on the ocean floor provide evidence of sea-floor spreading?
Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.

How are the rocks organized on the mid-Atlantic ridge?
They are arranged in a pattern with magnetic strips having reversed polarities.
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 are magnetic strips on the floor caused by?
Movement of the ocean crust
Why do magnetic strips appear on the sea floor?
metal cocaine

What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
How to make magnetic picture frames?
If you already have the picture frame, you can obtain some magnetic strips and glue them on; if you cover enough of the frame, it should stick to magnetic surfaces.
Why are there magnetic strips on the ocean floor what do they mean?
The earth maintains a magnetic field due to the metals that make up its core. Thus, all rocks are influenced by this magnetic field and "face" the direction the field is "facing". Every few hundred million years the poles switch, and with it the magnetic field. Similarly, all rocks "face" the new direction. Magnetic strips are indicators of when the magnetic field of the Earth changed.
