Answer:
Explanation:
Abyssal plain : very level area of the deep-ocean floor typically lying at the foot of the continental rise G
Guyot: A submerged flat-topped seamount H
Deep-ocean basin: portion of the seafloor between the continental margin and oceanic ridge; comprises 30 percent of Earth's surface C
Continental Volcanic Arc: Mountains are formed in part by igneous activity associated with the subduction of oceanic lithosphere beneath a continent A
Deep-Ocean Trench: Long, relatively narrow crease in the seafloor that forms the deepest parts of the ocean. D
Oceanic Plateau: extensive region of the ocean floor with thick accumulation of pillow basalts and other mafic rock E
Seamounts: An isolated volcanic peak that rises above the deep-ocean floor
Volcanic island arc: A chain of volcanic islands generally located a few hundred kilometers from a tench where active subduction of one oceanic slab beneath another is occuring; some trenches run parallel to an arc shapes row of active volcanoes
Answer:
Improvement in trensportation helped the city to get urbanized because many people could move to the city.
changes in communication helped the city to better communicate with each other, and lot of electric poll would have got built in
population growth helped made city over populated, and they had to make and apartment and more building to provide houses and many convenient place
migration to the city also makes the city over-populated
economic development could cause many changes to city, and there would be more building because of economic development
Couldn't read the last one pal, sorry.
Explanation:
Acculturation is the answer
Answer:
If the duration of life on Earth was on a scale of 20,000 days, the human species would be present in the Earth for approximately 9 days.
Explanation:
We can't be sure about the exactly age of the Earth, but we can base our calculus in a number between 4400 and 4600 million years, because the most accepted researches shows numbers in this span of time. We can take the average of those limits: 4500 million years.
On another hand the presence in the Earth of human species has not a precise date because of the it does not have a precise date for two main reasons, the scientific evidence does not include all the human species that existed on Earth but it is a very incomplete evidence and besides being an evolutionary phenomenon it is not easy to determine from what moment We can consider that a species belongs to the human race or not. In any case, we take the approximate date of the scientific evidence of the existence of human species in an age of 2 million years.
With both numbers we can calculate the proportion in the scale of 20 thousand years throw the following formula:
PHS = 20000 years . 2 million years / 4500 million years = 8.9 years
PHS: Presence of Human Species
