I got this from NationalGeographic.org

"Decompression melting involves the upward movement of Earth's mosty-solid mantle..."The rifting movement causes the buoyant magma below to rise and fill the space of the lower pressure. The rock then cools into new crust."
I hope this helps you!!!:)

What is the meaning of life. Is it to live, is it to die. I don't understand what is it.

Vilka [71]

Answer:

it depends on each person and that's what makes it so unique. You as a person gives your own life meaning. If your an artist maybe you live to share your passion of art with other people, if you have a partner you love maybe your meaning of life is to spend your time with them as happily and lengthly as possible. So in my opinion the meaning of life depends on the person, each person decides their meaning of life.

According to fossil studies episodic speciation is what mass extinction leads to. I think this is the best choice because mass extinction is a chain of events were a huge portion of species are killed. This process generates new species every time it occurs.

The right answer is D. Episodic Speciation
