1)Mid Ocean Ridge
2) Sea Floor Spreading; New crust is formed
3) It gets subducted and melts back into the mantle
4) 1. Molten Material (funny looking rocks)
2. Drilling Samples (age of rocks)
3. Magnetic stripes
5) Subduction: Old oceanic crust is more dense and sinks
6) Sonar
7) Trench
8) Sea floor spreading
9) Subduction
10) Mid ocean ridge
The answer is Nitrogen monoxide
It can only do that when one of the components of the mixture is a magnetic
material.
When you have that situation, you pass the magnet over the mixture ... shaking
the mixture if it's a dry mixture of powders or pieces ... and the magnetic part of
the mixture moves toward the magnet, while the nonmagnetic parts of the mixture
couldn't care less about the magnet and they just stay where they are.
Physical change because water is not a gas or change . you can see through it.
