1- The terrestrial lithosphere is composed almost of 80% by igneous rocks, they are also known as magmatic rocks and are formed at high temperatures due to magma solidification, they come from the superior mantle and terrestrial coast. Its texture is super resistant with significant hardness to obtain minerals and other derived materials. They can be divided into extrusive and intrusive.
2- Through experiments, Bowen has defined a sequence of mineral formation when a magma begins to cool. There are two types of magmatic differentiation defined by Bowen, the continuous series and the discontinuous series. In the continuous series the internal structure of the magma is not altered and all minerals have iron and magnesium, they are formed: aluminum, silica and sodium and calcium.
In the discontinuous series decreasing the temperature reacts the previously formed mineral with the existing liquid, and thus a new mineral with different internal structure and composition is formed. They are formed: olivine, pyroxena, amphibole and biotite.
These contributions allowed humans to develop and function better in their daily lives; thus societies managed to make big leaps in their economic and political development, as well as cultural production and their religion, whilst simultaneously leaving a legacy in evolutionary history for future generations.
Answer:
⇒The major lines of latitude are The EQUATOR, the TROPIC OF CANCER & CAPRICORN and none other than ARCTIC & ANTARCTIC CIRCLES!!
⇒ The major lines of longitude are The PRIME MERIDIAN (0 degrees) which runs through the Greenwich in London.
For seismograph A, the lag time is
5 minutes (difference between 6:10 and 6:05)
For seismograph B, the lag time is
15 minutes (difference between 6:25 and 6:10)
Assuming that earthquake waves have a constant velocity during the earthquake, then the seismograph with the shorter lag time is closer to the epicenter. So,
Seismograph is closes to the earthquake's epicenter
