Identify how magnetic symmetry can be used as evidence of sea-floor spreading?
On each side of the mid-ocean ridge is a mirror of the striped pattern on the other side. When drawn, these patterns show alternating bands of normal and reverse polarity that match the geomagnetic reversal time scale, scientists can assign ages to the sea-floor rocks. The youngest rocks were at the center, and the older rocks father away. The ages of the sea floor rocks are symmetrical. The only place on the ocean-floor where new rocks are formed are at the rift in mid-ocean ridge. hope this helps :)
What rocks are formed from broken rocks?
Clastic sedimentary rocks and Cataclasites (a form of metamorphic rock) are formed from broken rocks.
What is residual parent material?

Igneous rocks
Name the three types of rocks?
There are three types of rocks: 1)Igneous Rocks 2)Sedimentary Rocks 3)Metamorphic Rocks
Identify how magnetic symmetry can be used as evidence of sea floor spreading?
As the sea floor spreads the magnetic orientation in the rocks as they cooled is preserved. As the earth's magnetic field changes then a distinct pattern is imprinted in the rocks. If sea floor spreading is true then this unique pattern should be the same on both sides from the spreading point. Measurements of sea bottom rocks verify this symmetry is true. :)
