Notes:
Stars twinkle because they are point light sources. Passing through the atmosphere, the small beam of light constantly shifts by bouncing off particles in the air. The much closer planets appear instead as tiny disks in the sky. Their apparent sizes are usually larger than the pockets of air that would distort their light, so the effects of scintillation are negligible. Being closer, planets appear as discs, with the shifting of light from one side cancelling out the other.

Notes:
In geology, a nappe or thrust sheet is a large sheet like body of rock that has been moved more than 2 km or 5 km from its original position by faulting or folding. They form when a mass of rock is forced (or “thrust”) over another rock mass, typically on a low angle fault plane. The resulting structure may include large-scale recumbent folds, shearing along the fault plane.

Notes:
Day and night is caused by the rotation of the Earth on its axis. Earth takes about 24 hours to rotate around its axis once. When a place on Earth faces the sun, it has daytime. When it faces away from the sun, it has night.
