The Water Cycle

The water cycle is a spontaneous process that transfers water from one place to another around the globe. How Does Water Move From Land To Sky? Water bodies present in lakes, dams, and rivers vaporize from the hotness of the earth. It is the sun's heat that dries up water in the form of vapors, The vapors in the atmosphere condense together to form clouds. The clouds move in the sky with the flow of air. When it is full of water, precipitates in the form of rain, snow, or hail. In this way, water comes back to the earth and completes the water cycle. Different Ways To Vaporization: Evaporation - Evaporation happens just on the water's surface. The Sun plays a key role in the evaporation process. The heat generated from the sun produces most of the vapors in the atmosphere. Evaporation is the main natural process of forming almost 90% of vapors in the atmosphere. Sublimation - Water can directly reach to the atmosphere from ice in extremely cold conditions, p

Explanation of Photosynthesis

Can you imagine sunlight can be the food for living beings? It may seem weird but it is true. Plants are living beings they get food from the sun.  The process to get energy from sunlight is called Photosynthesis. The term is composed of two separate words.  Photo + Synthesis  "Photo" stands for light "Synthesis" stands for the combination of more than one thing. Sunlight, water, soil, and carbon dioxide gas are the bare necessity of plants to survive. We rely heavily upon plants to survive. Not only we get food from plants but also the oxygen for breathing. As plants take carbon dioxide which is harmful to us and release oxygen which is essential for us to survive.    What makes plants absorb sunlight?  All plants have chlorophyll. Chlorophyll is the compound that is responsible for absorbing the light. It is a pigment which absorbs blue and red color from sunlight and emits green color. That is why plants look green.  Explanation of Photosynthesis
