A geologist's job includes determining the history of an area.
Answer: Option C
<u>Explanation:</u>
Geologists are researchers who studies the materials available in the earth about their nature, characteristics and their age. Speaking of the age of the materials it helps to understand the history of the earth, Each area in the earth's history has undergone several civilizations and lifestyles.
Also, it has experienced various natural changes or special space happenings. By working on that with the founded specimens or collected evidence they can create reports. That can help to get a clear understanding of the climatic changes, history and topography of the species are in the world.
<u>Answer:</u>
<em>Cleavage is the splitting of minerals along natural planes of weakness
</em>
<em></em>
<u>Explanation:</u>
There are different physical features of a mineral that are used in the identification of species of fossils. The characteristics may include hardness, Fracture, tenacity, and, cleavage. The cleavage, therefore, occurs as a result of the strengthening of the weaker bonds and the greater lattice spacing that exist in the plane. The lattice accompanies the more fragile relationship along with the place because the link cannot maintain interatomic spacing.
The property of cleavage and positioning of fracture derived from structural species of the crystals.
Answer:
510
Explanation:
Recurrence interval involves the average estimated time or average spacing between events. It helps to estimate the time probability of an event taking place.
Calculating the recurrence interval we have:
![[(820 - 260) + (1200 - 820) + (2100 - 1200) + (2300 - 2100)] / 4](https://tex.z-dn.net/?f=%20%5B%28820%20-%20260%29%20%2B%20%281200%20-%20820%29%20%2B%20%282100%20-%201200%29%20%2B%20%282300%20-%202100%29%5D%20%2F%204%20)
After the calculations, the recurrence interval of the earthquake that caused the disruption is 510 years.
Answer:
North Africa is diverse. It is a myth that all North Africans have the typical Mediterranean look. It is the people you mostly see on TV and in movies.
Many North Africans can only be classified as North African Blacks. You rarely see them on TV or in the movies. They mainly live in the southern regions or as isolated communities, even in the north or the center of North African countries.
Genetically, the e1b1b haplogroup is shared by people in North Africa, in the Sahara and in Africa south of the Sahara. The palest Kabyles, the darkest Somali, the blackest Maasai and the “yellowish” San further south in Southern Africa carry the e1b1b hg.
The Sahara desert does not divide Africa genetically or phenotypically.
The differences between North Africa and Africa south of the Sahara are related to history and culture.
The history of North Africa is intertwined inseparably with European history (Roman Empire, the Greek Empire etc.), Persian history, Arab history and the history of the Ottoman Empire.
North Africa belongs to the Mediterranean world, northern coastal regions particularly (the food is typically Mediterrenean food). North Africa belongs to the Arab World. Arab culture is very strong and dominant. There is also a major influence of the Turkish culture.
