What is the explains the shape of the earth ?

So the shape of the Earth is round.

Explanation:

You know how when you look straight ahead out on the beach? The horizon is a line, right? Well, if the Earth were flat, that line would not exist. Instead, you would see a lot more of the ocean. Try it now and see what I mean. There is a limit to how far you can see, that is because if you stand on a sphere, and someone were to behind standing on the side of it, you wouldn't see them because you would be looking ahead, not down.

sadness is not good

explanation:

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
