All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil's properties – its texture, structure, porosity, chemistry and colour. Soil is made up of different-sized particles.
The moon's gravitational force pulls on water in the oceans so that there are "bulges" in the ocean on both sides of the planet. The moon pulls water toward it, and this causes the bulge toward the moon. The bulge on the side of the Earth opposite the moon is caused by the moon "pulling the Earth away" from the water on that side.If you are on the coast and the moon is directly overhead, you should experience a high tide. If the moon is directly overhead on the opposite side of the planet, you should also experience a high tide.
During the day, the Earth rotates 180 degrees in 12 hours. The moon, meanwhile, rotates 6 degrees around the earth in 12 hours. The twin bulges and the moon's rotation mean that any given coastal city experiences a high tide every 12 hours and 25 minutes or so.

All mass isn't all together in one area but is actually more spread out.
Answer:
b) About 31 times more energy
Explanation:
Lot of people get confused with the way in which the earthquake magnitude is calculated. The scale for measuring the earthquakes is logarithmic, so every whole number increase in magnitude represents a tenfold increase in the measured amplitude. This results in every consecutive whole number the earthquake to be 33 times more powerful than the previous one, so the difference in power between magnitude 7 and magnitude 8 is 33 times. If we take magnitudes that are not consecutive numbers, like magnitude 6 and magnitude 8, then the difference in power will be around 1,000 times.
