Compared to the surrounding material, mantle plumes rise toward Earth’s surface from the core-mantle

1 answer:

4 0

Compared to the surrounding material, mantle plumes rise towards the Earth's surface from the core-mantle boundary because they are hotter and less dense (3) than the surrounding material. A mantle plume is a large column of hot rock that rises through the earth's mantle. This plume is hot enough to cause the rocks in the lower lithosphere to melt. When the plume reaches the bottom of the lithosphere, it spreads out forming a mushroom shape cap. The lithosphere is then pushed up and stretched out. This forms magma chambers which feed the surrounding surface volcanos.

Answer: strong positive correlation

Explanation:

A positive correlation exists when the correlation coefficient that we've is greater than 0. This means that both variables that are given move in the same direction.

Since the correlation between the number of hours Brad studies and the grades he gets is 0.8, it means that there's a strong positive correlation due to the fact that the value is close to +1.

This means that the number of hours that Brad studied is a good predictor of

the grade that he gets in his examination but it's not perfect.
