Answer:
by introducing new method s of agriculture like land reclamation
Fossils can tell you that Pangea time really happened. Let’s say you find a fossil in North America for something normally found in Africa or a fossil in Europe for something that would otherwise be in South America. Wouldn’t that explain continental drift happened (the continents split)? It most certainly does.

Answer: 10, 100
Explanation:
Magnitudes are based on a logarithmic scale (base 10). For each whole number you go up, the amplitude of the ground motion recorded by a seismograph goes up ten times. Using this scale, a magnitude 5 earthquake would result in ten times the level of ground shaking as a magnitude 4 earthquake (and 32 times as much energy would be released).
1 unit increase corresponds to 10 fold increase in magnitude.
