The Sky

The sky is one of the most fascinating and beautiful phenomena in nature. It can change its color, shape, and mood depending on the time of day, the season, and the weather. The sky is the expanse of air and atmosphere that appears above the Earth's surface when one looks upward. The sky is part of the Earth's environment, and when we talk about the sky, we usually refer to what is visible from our planet's surface. It includes the region where one sees clouds, the sun, the moon, stars, and other celestial objects as well as atmospheric phenomena like rainbows and lightning. 

The sky is composed of different layers of gases, mainly nitrogen and oxygen, that are held by the Earth's gravity. The sun, the moon, and the stars are visible in the sky because they are much farther away than the atmosphere. The sun is the main source of light for the sky, and its position and angle affect how we perceive the color and brightness of the sky.

One of the most common phenomena that we observe in the sky is the blue color. The blue color is caused by a process, which occurs when sunlight interacts with the molecules of air. The sunlight consists of different wavelengths of light, each corresponding to a different color. The shorter wavelengths, such as blue and violet, are scattered more than the longer wavelengths, such as red and orange. This means that more blue light reaches our eyes from all directions, creating the impression of a blue sky.

However, the sky is not always blue. Sometimes, the Sky can have different shades of red, orange, yellow, pink, purple, and even green. These colors are caused by another process, which occurs when sunlight interacts with larger particles in the atmosphere, such as dust, smoke, pollution, or water droplets. This scattering affects all wavelengths of light equally, so the color of the sky depends on the angle of the sun and the type and amount of particles in the air.

In summary, the sky is the part of our environment visible from the Earth's surface and includes the atmosphere and celestial objects we see from our planet. Sky exists with delicate details that makes possible for all objects to function in a meaningful way for sustaining life.

The Universe: Origin & Constituents

Image
The Universe is a gigantic area of space and the whole lot that is found within it containing entire Matter, Energy, Clusters, Galaxies, Stars, Asteroids, Planets, and Living Creatures. It includes all that can be observed by telescopes as well as other scientific tools; besides, all other objects and phenomenon that we cannot detect directly like dark matter, dark energy, non-material etc...  It is estimated that the universe emerged somewhat around 14 billion years ago because of cosmological incident called as Big Bang. From that moment on, new galaxies, stars and other cosmic objects are being created and expanded continously.  Multiverse: Here briefly like to mention a speculative concept in cosmology and theoretical physics known as Multiverse that suggests the existence of multiple universes or domains, each with potentially different physical laws, constants, or conditions. These separate universes may exist alongside or parallel to our own.  The idea of a multiverse arises fro

CELL: FUNCTIONS

Image
The functions of cells Cells perform a variety of functions that are essential for the survival and reproduction of living organisms. Some of the main functions of cells are: -  Metabolism : The  sum of all the chemical reactions  that take place in the cell  to convert or use energy . Metabolism includes  catabolism , which is the  breakdown of molecules to release energy ; and  anabolism , which is the  synthesis of molecules to store or use energy . -  Growth : The  increase in size or number  of cells. Growth can be achieved by  cell enlargement or cell division .  Cell division  is the process by which a  cell splits into two identical daughter cells . There are two types of cell division:  mitosis , which  produces two diploid (2n) cells that are genetically identical to the parent cell ; and  meiosis , which  produces four haploid (n) cells that are genetically different from the parent cell and each other . -  Differentiation : The  process  by which a  cell changes its structu

Earth: Hydrosphere

Image
The hydrosphere is the term used to describe all the water on Earth, in any form. A planet's hydrosphere can be liquid, vapor, or ice . The hydrosphere includes water that is on the surface of the planet , underground , and in the air .  It includes oceans, seas, lakes, rivers, glaciers, ice caps, snow, groundwater, clouds, and water vapor. The hydrosphere covers about 71% of the Earth's surface and contains about 97% of the Earth's water . Some of the factors that affect the hydrosphere are precipitation, evaporation, transpiration, runoff, infiltration, percolation, melting, freezing, erosion, sedimentation, pollution, and climate change. Water Cycle The water cycle, also known as the hydrologic cycle , is the continuous movement of water between the Earth's surface and the atmosphere . The water cycle is essential for life on Earth, as it regulates the climate , distributes freshwater , and shapes the landscape. The water cycle has four main stages: evaporation, con
