Question

The change in the physical properties of earths interior at the mantle core boundary makes p waves ____ as they pass through the boundary

Answer 1

it makes p waves bend or reflect but they make them bend so the answer is bend. 

Answer 2

Bend

Step-by-step explanation:

P wave is a longitudinal earthquake wave that travels through the interior of the earth and is usually the first wave to be recorded by a seismograph. This is actually a wave that shakes the ground back and forth in the same direction and the opposite direction as the direction the wave is moving. But the change in any physical properties of earths interior at the mantle core boundary makes p waves bend through its boundaries.
