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.
Answer:
Topographic maps are map that show elevation through lines. When a slop is steep, the lines on a topographic map will be closer together.

Answer:
On 9 January 1857, the San Andreas fault segment between Cholame and San Bernardino broke loose at its northwestern end, and the rupture propagated southeastward in the great Fort Tejon earthquake with a magnitude of about 7.9.
Explanation:
The Fort Tejon earthquake, which occurred on January 9, 1857, is considered the strongest earthquake that shook the state of California. It is estimated at a strength of 7.9. Its strength is therefore comparable to that of the 1906 San Francisco earthquake. It occurred along the San Andreas Fault 362 kilometers between Parkfield and San Bernardino. The two plates that meet along this disturbance shifted up to nine meters during this quake.
California was still sparsely populated in 1857. Unlike the New Madrid earthquake of 1811, there are hardly any records of people who have experienced this earthquake. For this reason it is only known among seismologists. According to current research, its epicenter was located near the California city of Parkfield. However, it got its name because of the army camp Fort Tejon, which was located on the Tejon Pass, reported it.
Only one death was reported as a result of the earthquake. The person died in the collapse of an adobe house at Reed’s Ranch in Gorman, very close to the fault. Most of the buildings in Fort Tejon were badly damaged and several people were injured. Some buildings in Los Angeles were destroyed, but no major damage was reported.
