Explanation:
Why does the Earth spin faster at the equator than the poles?
a
Due to the temperature differences on Earth, the land/sea near the equator goes at a faster rate. The Earth spins faster there only during the summer months.
b
The Earth is much wider at the equator than at the poles. It must cover a larger distance in the same amount of time (24 hours).
c
Due to the tilt of the Earth on its axis, the equator gets more sunlight -- therefore making it spin faster.
Answer:
Specifically, Earth rotates faster at the Equator than it does at the poles. Earth is wider at the Equator, so to make a rotation in one 24-hour period, equatorial regions race nearly 1,600 kilometers (1,000 miles) per hour. Near the poles, Earth rotates at a sluggish 0.00008 kilometers (0.00005 miles) per hour.

When an earthquake occurs, two different types of waves are generated. These waves are called P waves and S waves. Examine the diagram, which shows how the waves travel through Earth. Which statement provides the best evidence of Earth’s structure, based on the information in the diagram?
A. The bending of S-waves shows that Earth has both an outer and an inner core.
B. Earthquakes provide no information because they cannot be detected all over Earth.
C. S-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.
D. P-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.
Answer:
Since S-waves do not travel through liquids, the evidence shows that Earth has an outer core layer made of liquid.
