Answer:
B. fossil content and spatial relationships among sedimentary rocks
Explanation:
Earth's geological scale. Geological division of the Earth from its origins 4.5 billion years ago, to the present. divided into four Hadeic, Archeozoic, Proterozoic and Phanerozoic eons, their names refer to the evolution of terrestrial life. These divisions do not have an exact temporal value, the extent of each division and subdivisions are marked by the geological evolution of the planet not by exact periods of time.
This division can be done thanks to the study of the different<u> fossils found and the analysis of the different sedimentary rocks found </u>and their relationship with the environment in which they are found.
The Phanerozoic eon, which we know best thanks to the existence of visible fossils, is divided into three ages: it was Paleozoic, it was Mesozoic and it was Cenozoic. The ages, in turn, are divided into periods, these in times and the latter in ages. Geological time is framed in a macro-temporal scale of variable stages that depend largely on large geological events that occurred during the history of the planet. It is called Precambrian all the time prior to the Phanerozoic eon, that is, it would include the three previous eons.
Recently the name Ediacariense has been added to designate a period (635Ma-540Ma), located at the end of the Precambrian, and whose name derives from the appearance of new animals and up to half a meter in size (Ediacara fauna). The precambrian is a supereón, which is the division on the geological scale above the eons, this being so large they lack importance for the study of the geological history of the planet.
Answer:so if 4.6M = 4.6 billion years, then 1m = 1billion years so...
1m = billion years
1cm= 1000 million years
1mm= 1million years.
Explanation: you can solve this by doing conversion or write down each years value. Since Cm is lower than M, so we know it will be in the thousands of millions. Since mm is lower than cm it will be in the one’s place.
The answer is A, severe weather is severe meaning dangerous
Yes, imperialism exists in the modern age. They are not exactly the same as the ones we read in our textbooks, but they do still exist in modern age. An example is Cultural imperialism. Where America influences others through the internet such as social media, music, brands, moves etc.
