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 happens when new basalt forms along mid ocean ridges?
Magma that has bubbled up through the crack in the Earth's surface.
What of the magnetic poles change over time?
Along the ocean ridges, as they spread and make new ocean floor, the minerals that can become magnetized point to the positive north pole. In past eons, the magnetized metals have pointed in the opposite direction.

What is the relationship between Chielo and Ekwefi?
Chielo is friends with Ekwefi, and they get along well. Chielo sometimes gives bean cakes to Ekwefi to give to Ezinma. However, when Chielo becomes the priestess, she becomes like a completely separate person with no empathetic relationship with Ekwefi. Ekwefi is afraid of this incarnation of Chielo.
What is main artery?
The aorta. This leaves the heart (left ventricle) loops over (aortic arch) and becomes the descending aorta. Their are other arteries that branch off along the way, carotid, brachial, etc. then the aorta splits into the femoral arteries.

What are 2 metamorphic minerals formed along oceanic ridges?
Minerals are not classified as metamorphic. The mid-oceanic ridges are generally considered to be areas where new basaltic crust is formed from uprising magma. The basalt is considered an igneous rock in classification.
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.

Why is so much basaltic magma erupted along mid-ocean ridges?
Lowered pressures decrease the temperatures at which basalt magma can partially melt from a rising plume of mantle peridotite.
What happens when new basalt forms along mid ocean ridges?

The magnetized coil running along the track called?
That is a linear motor.
Hardens to form new rock at mid-ocean ridges?
Sea- Floor Spreading molten material erupts through the valley that runs along the center of some mid-ocean ridges. This material hardens to form the rock of the ocean floor. Mid-ocean ridges an undersea mountain chain where new ocean floor is produced.
What are the medial ridges along the sacrum called?
The medial ridges along the sacrum are called the sacral crest. It is a series of tubercles that represent the processes of the sacral vertebrae.
Are mid-ocean ridges located mostly along coastlines?
No, mid-ocean ridges are not located mostly along coastlines. Mid-ocean ridges are underwater mountain ranges that form where tectonic plates are pulling apart. They are located in the middle of the ocean and can extend for thousands of kilometers.
