Those links are completely bogus. The first one for instance starts with a fake picture of the globe earth, what a complete joke.
Maybe you can fool flat earth society with these links, not the real flat earth truth movement. Is this all you can get?
Instead of that:
Show me the curvature. Genuine footage in real time, not fake nasa paintings or artist impressions. No go pro camera footage with fisheye lenses.
71% of earth is water. Show me how and where exactly water starts to curve. Give me a genuine footage of that, not nasa paintings and cgi manipulation fakery.
Pacific ocean occupy almost 1/3 of earth. Show me real time footage how it is curving.
Show me live feed of people in Australia walking upside down on the bottom side of the imaginary globe.
Demonstrate me how water can stick to a 1000+mph spinning ball. (hint: if you put water in a cup it become a cup. If you put water on a ball, it falls off)

fuck your teacher... wtf !!!!!! did u ever go school??
what you missing is that there is no UP there is no DOWN
gravity = DOWN, less-gravity=UP
center of earth = a lot of gravity = down
SKY = less gravity = up
that's why the water pressure is big and that's why the water is in curvature , and that's why people in australia are not UPSIDE down,
