Answer:
Convection in the asthenosphere.
Explanation:
Convection in the asthenosphere
Heat which is present in the Earth maintain the malleability of the asthenosphere , and hence provides lubrication to the Earth's tectonic plates for movement .
The convection current that is generated in the asthenosphere , tries to push the magma upward via the vents that are present in the volcanoes and thereby spreads and create a new crust .
And this generates a hotspots on the Earth's crust .
Answer: Body waves travel through earths interior while surface waves travel along the earths surface. Body waves travel more rapidly than surface waves.
Explanation:
Given:
O, P, and Q be distinct collinear points with PQ=3.
P′ and Q′ be the images of points P and Q under dilation from point O with scale factor 4.
To find:
The length of the image segment P'Q'.
Solution:
We know that,

P′ and Q′ be the images of points P and Q under dilation from point O with scale factor 4. So, Segment P'Q' is the image of segment PQ and the scale factor is 4.

It is given that PQ=3.

Multiply both sides by 3.


Therefore, the length of the image segment P'Q' is 12 units.

Pretty sure its called the 38th Parallel, or the Demilitarized Zone. :)
