Which of these statements is correct about P and S seismic waves?

Both P and S waves travel along Earth's surface and their amplitude decreases with depth into Earth.

Both P and S waves travel with the same speed through Earth and their amplitude increases with time.

P waves are radiated along a single direction but S waves are radiated along all directions.

P waves change the volume of the medium through which they travel but S waves do not change the volume of the medium.

Answer 5

P waves change the volume of the medium through which they travel but S waves do not change the volume of the medium.

Answer 6

The first three steps in the formation of the sun are listed below.
1.A cloud of gas and dust called nebula spins slowly.
2.The nebula collapses due to condensation of gases.
3.The cloud spins faster as it collapses.
Which of these statements best describes the next step in the formation of the sun?
The contracting nebula flattens into a disk with a bulge at the center.

The gas particles in the nebula repel each other and move apart.

The nuclear fission of the gas molecules releases large amount of energy.

The sun is created at the outermost portion of the condensed nebula.
