Explanation:
Wegener noticed while looking at the maps that some parts of the continents, especially South America and Africa, seem to match up perfectly. This led him to think that maybe the continents in the past were actually connected, but because of some force they moved apart. He went out public with his hypothesis, but it was largely rejected, and he was laughed at and ridiculed, as the scientists thought that there's no force that can move the continents. Wegener didn't stop there, and he continued to look for clues, and finally managed to find some clues at the topography of the Atlantic Ocean. He noticed that the mid-ocean ridge is the highest, but as you move away from it, the sea mounds are becoming flatter and lower, thus a sign of erosion, and he actually turned out to be right.
Answer:
Explanation:
Simplify -3\times -5−3×−5 to 1515.
15=-2\times -20
15=−2×−20
2 Simplify 2\times -202×−20 to -40−40.
15=-(-40)
15=−(−40)
3 Remove parentheses.
15=40
15=40
4 Since 15=4015=40 is false, there is no solution.
No Solution
Flooding because of dam failures, subsidence, etc. are secondary effects, whereas shaking of structures, liquefaction, etc. by faulting are direct damage.
<h3>What are secondary catastrophic effects?</h3>
Secondary effects are indirectly associated with the occurrence of a catastrophic event (in this case, a earthquake).
Moreover, direct damage makes reference to eventual immediate effects that such catastrophic events may have.
In conclusion, flooding because of dam failures, subsidence, etc. are secondary effects, whereas shaking of structures, liquefaction, etc. by faulting are direct damage.
