What properties of iron bearing minerals on the seafloor support the theory of seafloor spreading?

∙ 11y ago
iron bearing minerals can record Earth's magnetic field direction. when Earth's magnetic field reverses, newly formed iron bearing minerals will record the magnetic reversal. magnetic reversals show new rock being formed at mid-ocean ridges. This helped explain how the crust could move

∙ 11y agomagnetic alignment. seafloor "spread" is a very slow process and takes long enough that the magnetic poles switch. scientists look at the magnetic alignment and where these bands of magnetism lie. also they use carbon dating

What happen to iron bearing minerals that are heated at curie point?
Iron-bearing minerals lose their magnetic properties when they are heated to the Curie point.
How the ages of the rocks on the ocean floor support the theory of seafloor spreading?

What is a synonym for a metal bearing mineral?
The word for unrefined rock or raw minerals is "ore." There is no single-word synonym.
What type of rock is lead?
Lead is an elemental mineral but is most often found in lead bearing minerals like galena and wulfenite.
Paleomagnetism is proven by evidence of changes in?
Evidence of paleomagnetism can be found in basalt that has cooled from lava. Other evidence is that any rock with magnetic minerals are presents, and sedimentary rocks where minerals form from ion bearing ground water.

Where do you get minerals from?
From their ore's, ie from their individual mineral bearing rocks.
What is the meaning of tale-bearing?
Tale-bearing means spreading gossip or secrets that might cause harm or trouble. It is considered a sin of the tongue and is a serious sin in Judaism.
What does red soil have in it?
Iron bearing minerals which oxidise to red/brown Iron Oxides (rusts).

What is a water-bearing layer of rock sand and gravel?
I have never heard a specific noun for it but but the adjectives hydrated, saturated, or water-bearing could apply. Many minerals will adsorb water directly into their molecular crystalline structure, they are called "hydrated" minerals. If the water is simply soaked into pores in the rock like wet sand then we say it is saturated or water bearing.
