Color

Color (American English) or colour (British English; see spelling differences) is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, and others. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. The science of color is sometimes called chromatics, colorimetry, or simply color science. Physics of color Perception

What Are Monsters?- Famous Monsters Explained Here What are Monsters? Dwelling around in dark places and corners, these famous monsters can be found under your bed, in your closet or behind closed bathroom doors. But most definitely, they are surely to be found living in your head. Creeping, lurking and lying in wait, their main motive is to scare anyone who may be crossing their path. But what are monsters actually? The word monster is derived from the Latin word "monstrum", which in literal terms means omen. It is a creature with an evil mind with structural defects or deformities physically, which inspires horror or disgust. Whether real or imaginary, these famous monsters are abnormal with deformed body parts which are frightening to look at. Some of these monsters have become real famous over time, because of their reputation for their fear factor capabilities and the eerie way of scaring people. Sometimes the monster can be a display of God’s anger, sometimes an omen of the future, or even a symbol of moral virtue or vice.

Alles over water - Water startpagina Mountain Introduction A mountain can be defined as an area of land that rises abruptly from the surrounding region. A mountain range is a succession of many closely spaced mountains covering a particular region of the Earth. Figure 1: This image shows the topography of both land and ocean surfaces. Some mountains are volcanic in origin forming where rising magma breaks through the Earth's surface. Figure 2: The following illustration classifies the Earth's mountainous areas by elevation. The Earth's mountain ranges have various ages of formation. Evolution of Mountains Figure 3: Volcanic rocks found in mountains often originate from magma plumes that have migrated up through oceanic crust. Geologists have developed a general model to explain how most mountain ranges form. accumulation of sediments; an orogenic period of rock deformation and crustal uplift; and, a period of crustal uplift caused by isostatic rebound and block-faulting.
