Exam 27: the Earths Interior, Revisited: Seismic Layering, Gravity, and the Magnetic Field

Using the image below,explain why the P-wave velocity drops drastically at the core-mantle boundary.Also,explain why the P-wave velocity speeds up at the inner core-outer core boundary.

If a gravity anomaly is negative,what does that imply about the material underground?

In the picture below,when the ship is filled with cargo it sinks into the water until the mass of water displaced is equal to the mass of the cargo.The ship is then said to be ________.

If an S-wave is traveling through rock when it encounters a magma chamber,the S-wave will ________.

Which layer of the Earth has the highest density?

A positive magnetic anomaly is produced when the measured magnetic field strength is ________ the expected magnetic field strength.

Identify the layers of the Earth,from the outside to the interior,using the illustration below.

Using the graph below,why is the outer core liquid,but the inner core solid?

A mountain range made of basalt would produce a(n)________ gravity anomaly.

What causes the velocity of a P-wave to speed up when it enters the inner core?
