Because of the need for water and other resources. Central Australia is mainly desert, and has a hot, dry climate.
The difference between the two mentioned magnitudes is 4.
A magnitude 1 earth-quack is 10000 times bigger than a magnitude -3 earth-quack. On the other hand, it is 1000000 times stronger in terms of energy release.
Note: To calculate the difference in energy between two earth-quacks, first you calculate the difference between their magnitudes and then you raise 10 to the output you obtain.
Answer: If the sin 30° = 0.5, then the cos 60° = 0.5 (same as 1/2)
It’s obviously round first piece of evidence is the countless accounts of people in space stating it is round, and you’ve got to think about it. Why would they lie and create this international conspiracy? What would be the point in saying the earth is round when it’s flat? Furthermore, second piece of evidence is that you can see the curvature of the earth from an airplane, if you go into the cockpit of a commercial airplane when at a cruising altitude of around 40,000feet you can see the curvature! So it wouldn’t just be people who have been In space lying it would be countless pilots, videos, photographic evidence falsified and for what?!
Overall, the earth is round.
