What else can I help you with?
When new basalt forms along mid-ocean ridges it become magnetized?
accorsing to the earths magnetic field
What types of rock are mid ocean ridges made of?
The mid-ocean ridges are made almost entirely of basalt, because this is where new oceanic lithosphere is being formed. In fact, oceanic plates in there entirety are made up almost entirely of basalt.(igneous rock)
Can you get primary basalt at subduction zone?
Basalts tend normally to form at mid-ocean ridges or at inter plate hotspots. However a specific type of Basalt known as Boninite which has a high silica and magnesium content and which is formed in the fore-arc and back-arc basins of subduction zones. This however is NOT a primary basalt.
Where is the most of the basalt found on earth?
Most Basalt is found mostly in oceanic plates of Earth.
How do strips of magnetized rock on the ocean floor provide evidence of sea-floor spreading?
Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.

When new basalt forms along ocean ridges it becomes magnetized how?
While it is molten it is above the Curie temperature and is not magnetic, as it cools below this temperature the ambient magnetic field becomes "frozen" into the basalt.

What is the connection between high temperatures measured at ocean ridges and the formation of basalt ridges?
realate the high tempertures measured at the mid-ocean to the formation of basalt at the ridges
What makes up the bedrock under the oceans?
The bedrock under the oceans is primarily composed of basalt, a type of volcanic rock that forms from the solidification of magma beneath the Earth's crust. Basalt is rich in iron and magnesium minerals and is commonly found in oceanic crust. It is created through the process of seafloor spreading at mid-ocean ridges.
Does basalt form on the oceanic crust?
Yes, basalt forms on oceanic crust through volcanic activity at mid-ocean ridges and hotspot volcanoes. It is the most common rock type on the ocean floor and is created from the solidification of molten lava.
How old is basalt?
Basalt can be hundreds of millions of years old or it can be minutes old, just solidified from basaltic magma at the mid-ocean ridges.
What do the Atlantic and pacific oceans have in common?
there both oceans and They both have mid-ocean ridges.
Can you see a picture of ocean that has ridges?
go to google and type mid ocean ridge, and there will be pictures of oceans with ridges!
Is there evidance that there are ridges of solidifies magma near the centres of many oceans?
yes
What kinds of rocks are associated with ocean ridges?
Basalt rocks are commonly associated with ocean ridges due to the process of seafloor spreading where magma rises to the surface, cools, and solidifies. These basaltic rocks form the oceanic crust along the ridges.
What types of rock are mid ocean ridges made of?
The mid-ocean ridges are made almost entirely of basalt, because this is where new oceanic lithosphere is being formed. In fact, oceanic plates in there entirety are made up almost entirely of basalt.(igneous rock)
