When molten material hardens into the rock on the ocean floor the domains of the iron it contains?
line up in the direction of Earth's magnetic field
Why is volcanic ash magnetic?
Volcanic ash is magnetic because the ash has iron in in the objects the lava/magma burns. Or the ash already has iron from the mantle of the Earth burning into the magma of the core.
Why does volcanic rock magnetize?
Volcanic rock, especially basalt, contains some iron. When the rock is still molten the particles of iron are free to move, but are influenced by Earth's magnetic field. When the lava hardens into rock these iron particles are locked in place, essentially recording the orientation of Earth's magnetic field.
Who is the person who makes table doors out of iron?
the person who makes tables, doors and objects out of iron
Where are magnetic bands formed to ocean ridges?
It's formed in magma before it is oozed up through the ocean floor at the Mid-Atlantic Ridge. While it is still liquid, the iron molecules in the lava can orient themselves along the magnetic lines of force that envelope the earth.
What was the composition of the early ocean?
The primitive ocean was composed of dissolved iron. This could have given it a reddish colour. The iron existed from volcanic activity. After the evolution of photosynthesis, the iron precipitated out and oxygen has composed the qualities it has today.
How would this history of reversals show itself of the ocean floor?
it tugs on the iron pieces in the sand causing ripples.

Why were earths oceans originally green?
Because the Earth's first atmosphere/ocean system didn't have free oxygen, dissolved iron accumulated in the oceans, giving them a green color. As oxygen became available, it combined with the iron and settled to the sea floor to form banded iron formations (BIFs). Once the iron was "rusted" out of the water column, the ocean color changed from green to blue.
What happen to the Titanic after it sank?
It remained on the ocean floor for 70 years where it slowly decayed and has been eaten away by bacteria which eat iron. In the mid 80's Robert Ballard rediscovered it and occasional expeditions go down to the wreck to study it.

What has the author Hans Pettersson written?

What causes a ships iron anchor to sink to the ocean?
Gravity causes the ships iron anchor to sink to the ocean.
Why does the magnetic polarity of the ocean floor change in stripes?
The Earth has two poles, the north pole and the south pole that behave like giant magnets. The rock on the ocean floor contains iron. The rock began as molten material that cooled and hardened. As the rock cooled, the iron bits inside lined up in the direction of Earth's magnetic poles. This locked the iron bits in place, giving the rocks a permanent "magnetic memory". The stripes are significant because of the "magnetic memory" giving us an idea of what occurred when sea-floor spreading took place.
