Why do earthworms bring piles of soil to the surface?
The piles of soil are the worm casts, (faeces) which the worm excretes after feeding. These may be pushed to the surface as the worm clears out his tunnel or deposited on the surface as the earthworm feeds above ground. As the worm will not venture far from its burrow it might explain as why they are situated around the opening of the hole.
What was the evidence that Earth was round before there were photos from space?
Before space photos confirmed Earth's roundness, evidence included observations such as the way ships disappear hull-first over the horizon, the curved shadow Earth casts on the Moon during a lunar eclipse, and variations in star visibility when traveling north or south. Additionally, early astronomers like Aristotle noted the circular shape of the Earth's shadow during eclipses and observed that different constellations are visible in different latitudes, supporting the idea of a spherical Earth.
How did they figure out the moon and earth was round?
The earth reflectsAnswer:The Earth was found out to be spherical because it always casts a shadow (during eclipses of the Moon) that was either circular or portion of a circle (partial eclipse). There's only one solid shape that always appears to be circular, regardless of view point, and that's a sphere.I'm not sure about the Moon, but I assume that it was pretty much the same process - it always appears as a circle or part of a circle.

What are color casts?
In photography, color casts are overall color shifts in the resulting image as compared to what is normally seen by the eye. If caused in the printing stage, it is due to deviations in time, temperature, chemistry, or exposure, or incorrect filtration in the enlarger. If caused in the image capturing stage, it is usually a mis-match of the color temperature of the dominant light source versus the color temperature rating of the film in use. This can usually be prevented or minimized by choosing the right film type for the color temperature of the lighting and proper filters on the lens, or by over-powering the dominant lighting with electronic flash.
