What is a Water Cycle ?

Water Cycle is a naturally occurring Hydrological cycle by which water is recycled back to the earth in the form of rain to help sustain life on the planet because water is the main ingredient without which life does not exist on this planet.

"The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it flows back into the oceans, where it will once more evaporate. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth." - https://pmm.nasa.gov/education/water-cycle

Hence the Water cycle essentially tell us the evaporation of water in the gaseous form (water vapor) into the atmosphere and due to temperature changes condenses and falls back on earth in the form of rain thus sustaining life on earth.

What is Reflection of Light ?

Reflection is a very common word and is related to the fields of physics and mathematics. The basic meaning of a reflection is  ‘Something Returned in Response’ . Even in our conversation we use this term at times, to mean a some one’s reaction. In optics, it relates to an image of an object. Light rays are basically wave motions and they are capable of being reflected by an interface in between two mediums. Such interfaces are called  Light Reflectors .  The most common Light reflector is the one we use many times a day, which is nothing but a plane mirror. But it is not only a plane mirror reflects light. Even a curved mirror does that though the nature of reflection of light by curved mirrors is different.

What is a Harvest Moon ?

The Harvest Moon is the full Moon nearest the start of fall or the autumnal equinox. This usually means it coincides with the September full Moon, though it can also fall nearer to the October full Moon, occurring anywhere from two weeks before to two weeks after the equinox. In  2017 , the Harvest Moon will rise on  October 5  at 2:40  P.M. EDT. WHY IS IT CALLED THE HARVEST MOON? For several evenings, the moon rise comes soon after sunset. This results in an   abundance of bright moonlight early in the evening , which was a traditional aide to farmers and crews harvesting their summer-grown crops. Hence, it’s called the “Harvest” Moon!

What is a Blue Moon ?

A "Blue Moon" is a fairly infrequent phenomenon involving the appearance of an additional full moon within a given period. But which period — there are two definitions of the term, and one was borne out of a misunderstanding of the other. The older meaning defines a Blue Moon as the third full moon in a season that has four full moons. Called a seasonal Blue Moon, this occurs about every 2.7 years. Why the third moon? Seasons normally have three full moons, and some of them, for traditional and religious reasons, must occur at specific times of the year. The other meaning is that a Blue Moon is the second full moon within a single calendar month. This definition — a monthly Blue Moon — has gained popularity in recent years because of a misinterpretation of an almanac's original definition. Blue Moons are not typically blue in color — that happens only, well,  once in a Blue Moon , but there is the possibility for a hint of blue in any full moon. YouTube Li...
