What Rocks formed by molten material?
a molten rock
How do rocks get magnetized?
They may contain naturally occurring magnetic minerals.
How are magnetic rocks magnetic?
They have the electromagnetic force in which two objects are attracted to one another in a specific field or range. It happens usually when the rocks contain iron which is the most important magnetic material.
When molten material hardens into rock on the ocean floor the domains of the iron it contains what?
When molten material hardens into rock on the ocean floor, the domains of the iron it contains align with the Earth's magnetic field at that time. This alignment occurs as the molten rock cools and solidifies, effectively locking in the magnetic orientation. As a result, the rocks serve as a historical record of the Earth’s magnetic field, allowing scientists to study past geomagnetic reversals and plate tectonics.
What three types of evidence provided support of the theory of sea-floor spreading?
three are : eruptions of molten material magnetic stripes in the rock of the ocean floor and the ages of the rocks themselves :)

Can Molten rock material from which minerals can crystallize be called magma?
Yes, molten rock material from which minerals can crystallize is called magma when it is below the Earth's surface. Once the molten rock material reaches the Earth's surface, it is referred to as lava.
Is basalt magnetic?
Basalt itself is not inherently magnetic, but it can contain magnetic minerals such as magnetite. These minerals can make some basaltic rocks exhibit magnetism, especially when they have been cooled from molten lava. The magnetic properties of basalt can also be influenced by the conditions under which it formed and the presence of other minerals. Overall, while basalt can have magnetic characteristics, it is not universally magnetic.
The molten material deep inside earth from which igneous rocks is called what?
magma
Which rocks would most likely contain a fossil in rock and minrol?
Sedimentary rocks, such as shale, sandstone, and limestone, are most likely to contain fossils. These rocks form from the accumulation of sediment and often preserve the remains of plants and animals. Fossils are less commonly found in igneous and metamorphic rocks, as these rocks form from molten material and intense pressure and heat, which usually destroy any existing fossils.
What common rock is formed from the solidification of molten material?
Igneous rock is formed from the solidification of molten material, such as lava or magma. This process can occur either above or below the Earth's surface and results in rocks like basalt, granite, and obsidian.
What happens to the rocks along the ridge when new molten material erupts?
The molten material then spreads out, pushing the older rock to both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. Then more molten material flows into the crack. The material splits apart the strip of solid rock that formed before, pushing it aside.
