Answer:
C. P waves move matter back and forth, in a direction parallel to the direction of the wave, while S waves move matter up and down, perpendicular to the direction of the wave.
Explanation:
P and S - waves are both called seismic waves. They are produced during deformation within the earth.
Usually, P or Primary waves have the fastest velocity and arrives at the seismic station first. Secondary, Shear or S-waves follows P-waves.
- P-waves are body waves that propagates within a body. They cause movement internally.
- Secondary waves are surface waves. They move on the surface of earth.
- One way to also distinguish between these two seismic waves is that, P-waves are longitudinal waves that travels parallel or longitudinally to the source.
- Secondary waves moves in an up and down motion pattern. They propagate transversely to their source.
Vast, circular to elliptical dark-colored areas on the moon called maria represent <u>very large impact</u><u> craters </u><u>filled with </u><u>basaltic lava</u>.
As the brightest and largest object in our night sky, the Moon softens the axial wobble of our home planet, making it a more habitable planet, resulting in a relatively stable climate. It also causes the tides, creating rhythms that have guided humans for thousands of years.
Without the Moon, a day on Earth would only last 6 to 12 hours. A year can be more than 1000 days. This is because the earth's rotation slows down over time thanks to gravity (or the gravitational pull of the moon). Without it, the days would fly by.
