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 evidence supports seafloor spreading?
Evidence supporting seafloor spreading includes the symmetrical patterns of magnetic stripes on either side of mid-ocean ridges, which show reversals in Earth's magnetic field over time. Additionally, the age of oceanic crust increases with distance from the ridge, indicating that new crust is formed at the ridge and gradually moves outward. The presence of deep-sea sediments also supports this theory, as they are thinner and younger near the ridges and become thicker and older further away. Finally, the distribution of earthquakes and volcanic activity along mid-ocean ridges aligns with the movement of tectonic plates.

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 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.
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.
What happens when new basalt forms along mid ocean ridges?
Magma that has bubbled up through the crack in the Earth's surface.
Rock that makes up oceanic crust?
the answer is Basalt.i know this because i looked it up in a science book.
Where is basalt when it cools?
Basalt forms when lava cools and solidifies on the Earth's surface, often in volcanic regions. It is commonly found in areas with recent or ancient volcanic activity, such as volcanic islands or along mid-ocean ridges.

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.
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.
