Stealthily

Reptiles tend to avoid confrontation through camouflage. Two major groups of reptile predators are birds and other reptiles, both of which have well developed color vision. Thus the skins of many reptiles have cryptic coloration of plain or mottled gray, green, and brown to allow them to blend into the background of their natural environment. Aided by the reptiles’ capacity for remaining motionless for long periods, the camouflage of many snakes is so effective that people or domestic animals are most typically bitten because they accidentally step on them.

Poppy in the sunset

Sunset or sundown is the daily disappearance of the Sun below the horizon as a result of Earth’s rotation.
The time of sunset is defined in astronomy as the moment when the trailing edge of the Sun’s disk disappears below the horizon. Near to the horizon, atmospheric refraction causes the ray path of light from the Sun to be distorted to such an extent that geometrically the Sun’s disk is already about one diameter below the horizon when sunset is observed.

Surface Tension

The shape of the drops is caused by the surface tension of the water. The only reason the drop of water isn’t completely spherical is because of the force of gravity pulling down on it. In the absence of gravity, the drop would minimize the surface area in order to minimize tension, which would result in a perfectly spherical shape.

Raindrops

Raindrops begin forming when water vapor condenses on micrometer-sized particles of dust floating in the atmosphere. The dust particles grow to millimeter-sized droplets, which are heavy enough to begin falling. As they fall, the droplets accumulate more and more moisture, until they become the large raindrops that we see here on the ground.
