You again ? Short-cutting your home work ?
Well, the answers are :
** At the equator. Because any point on equator will travel the largest distance than any point on the other options.
** 82. If you add up all the electrons in different shells (2+8+18+31+18+4) it gives you total number of electrons, each carrying a unit negative charge. To keep the atom neutral, we have to balance the total negative charge due to this 82 electrons by equivalent positive charge. This can only be done by 82 protons, each having a unit positive charge.
** Mafic magma has a low silica content, low viscosity (although not always) and forms mafic rocks which are dark coloured. So your third option is correct.
**Both diamond and graphite are different forms of carbon (Polymorphs). They are basically nothing but carbon, but the difference is in their molecular structure. So the answer is your third option.
**Calculate yourself. A complete rotation of earth, i.e., 360 degrees takes 24 hours (24 X 60 minutes). So 1 degree is (24X60)/360 =4 minutes.
Next, time do it yourself. Depending on others is going to harm you.

Epicenter is the point on the Earth's surface where the earthquake originiates. Within the earth it is called the focus.

Use the Mercalli scale to determine the strength of an earthquake based on damage, etc.

That's all I can remember about Geology, sorry.
