Answer:
Options (1), (2) and (3)
Explanation:
Alfred Wegener was the person who first invented the continental drift theory. He observed that the continents move from one place to another with respect to a fixed point. He put forward many pieces of evidence but he was unable to explain the main mechanism that is responsible for these motion of continents.
The pieces of evidence that were given by Alfred Wegener supporting the continental drift theory are-
(a) The continents move slowly and continuously from one place to another and the edges of these continents perfectly match with the other.
(b) Similar fossil assemblages were found in currently separated continents.
(c) Similar rock types are also found and suggested that the continents were once all together forming a huge landmass which is known as the Pangaea.
Later this theory was modified into a more simple and universally accepted theory which is commonly known as the Plate tectonic theory.
Hence, the correct answers are options (1), (2) and (3).
Answer:
Usually famine causes angst between the weakened civilation so the owners of said territories usually hunt for more fertile land so they can sustain their growing population without having being thrown out of power and slain, its often better to satisfy the people who you govern rather than to exterminate to govern the population steadily.
and to own more land is more money and more power for such rulers, if they own more land they can tax more people, and if they own fertile land they can grow crops to sustain themselves, and the people they govern, satisfying the ruler AND the people.
Natural elements typically erode ancient ( and all ) buildings and structures overtime. That and an increasing amount of tourist attraction also doesn’t help the decaying... well everything. An article from the guardian supports this and even says that last year the EU threatened to remove the funding of the Great Pompeii Project which conserves and restores this ancient site.
