Dry Snow Avalanche Blast Of Air Avalanches
517 wordsWhat is a avalanche? To most of you it is the fall of snow from the top of a slope. Well you are partially right. It is snow but it can also be several other things such as soil, rock, ice, or volcanic lava. Although most of the time a avalanche is snow it can be rock or soil. Most avalanches occur on slopes exceeding 30 degrees (Encarta 1. ) They are caused by temperature, creeping snow, or vibrations. There are three main types of avalanches (Walker 6 - 7. ) They are slab, dry-snow, and wet-sn...

Carbon Dioxide Dry Season
3,157 words... "The ants's unless lies in the evolutionary concept of kin selection" (Hoyt 1996). This concept occurs when members of a species work for the survival of relatives - genes by descent from a common ancestor rather than for one's survival of its own offspring (which is called individual selection). This is a very complicated process in which many people have devoted their lives to its study. The gathering of food by the leaf cutting ants is a complex series of interactions and communication wh...

Table Above Shows Time For 40 Vibrations Pendulum
701 wordsA simple pendulum consists of a mass called the pendulum bob suspended from a support by a thread. A complete vibration of a pendulum consists of one swing over and one swing back. The time for a complete vibration is called the period (T) of a pendulum. This is usually measured in seconds. When a pendulum swings through a small arc, its bob is undergoing sample harmonic motion. The force causing the bob to swing along its arc is greatest when its speed is least. The force is least when the spee...

Back Of The Head Optic Nerve
1,395 wordsToday, there are many forms of imaging available to the medical profession. Among the more well-known types include x-rays, ultrasounds, CT scans, PETscans, and the most groundbreaking, the MRI. One lesser known form of imaging is the technique of evoked potentials. The evoked potential uses stimulation of the body to force activity in the brain. Using electrodes, a clinician can take signals directly from the brain without any intrusive methods. The electrodes remain on the surface of the skin ...

Psychedelic Drugs Physical Body
1,003 words... on on the attention itself in a specific chakra, brings about a condition in that chakra, in which its vibration structure is harmonically and geometrically aligned in all of its planes of manifestation or rates of vibration. This creates common node points in the inner plane structure of the chakra. Vibrations of different frequencies and different wavelengths all begin and end together at these common node points. This is made possible by the fact that the wavelengths of the various vibrat...

Frank Herbert Final Battle
1,861 wordsThis book all started with the family Atreides landing on plant Arrakis, commonly known as Dune. The planet Dune was the centre of the universe due to its immense amounts of spice. This spice is greatly needed for all planets as fuel and for raw materials. The family Atreides were asked by Emperor himself to go and mine the spice on the planet. Their greatest enemy the Harkonnens's, were also on Dune. These two families mining the precious spice on the same plant would lead to great troubles and...

Fibre Crystal Mid Infrared Lasers
1,998 wordsFibre crystal mid-infrared lasers As we know, a laser is an optical oscillator made out of a gas, liquid or solid with mirrors at both ends (see, e. g. , The Computer Language Company Inc. , 2007 b). To make the laser work, the material is pumped with light or electricity. This pumping has excited the electrons and has caused them to jump to more high orbits. Some electrons do spontaneously drop back to lower energy levels what releases photons (i. e. quantum's of light). The photons do then sti...

Earths Surface Ground Motion
851 wordsAn earthquake, one of the most destructive natural phenomena, consists of rapid vibrations of rock near the surface of the earth. It is the most terrifying of all natural phenomena and has brought fear since ancient times because of its sudden unpredictable occurrence and enormous capacity of destruction. A single shock usually last no more than a few seconds, although several quakes may last for as much as a couple of minutes. The quake as felt on the surface is always the result never the caus...

Shake Or Tremble Intensity Is Measured By Testing Word
259 wordsAn earthquake is a natural disturbance, characterized by a convulsion or concussion of the ground. Earthquakes originate at a point within the crust, when a force pushing on a mass of rock causes it to slip suddenly. Energy is released and travels, through rock, to the surface in the form of waves causing vibrations and shaking. The word itself comes from the word earth, meaning ground or soil, and quake, meaning to shake or tremble. The word earth comes from the Middle English either, which com...

Hearing Loss Paying Attention
1,121 wordsThe ear is the organ of hearing and balance in vertebrates. The ear converts sound waves in the air, to nerve impulses which are sent to the brain, where the brain interprets them as sounds instead of vibrations. The innermost part of the ear maintains equilibrium or balance. The vestibular apparatus contains semicircular canals which in turn balance you. Any movement by the head, and this apparatus sends a signal to the brain so that your reflex action is to move your foot to balance you. The e...

Mid June Day Telling Your Brain Body
1,335 wordsHow does a human hear? When an object makes a noise, it sends vibrations (better known as sound waves) speeding through the air. These vibrations are then funneled into your ear canal by your outer ear. As the vibrations move into your middle ear, they hit your eardrum and cause it to vibrate as well. This sets off a chain reaction of vibrations. Your eardrum, which is smaller and thinner than the nail on your pinky finger, vibrates the three smallest bones in your body: first, the hammer, then ...

Charleston S C Volcanic Eruptions
2,884 wordstrembling or Natural Disasters earthquake, trembling or shaking movement of the earths surface. Most earthquakes are minor tremors. Larger earthquakes usually begin with slight tremors but rapidly take the form of one or more violent shocks, and end in vibrations of gradually diminishing force called aftershocks. The subterranean point of origin of an earthquake is called its focus; the point on the surface directly above the focus is the epicenter. The magnitude and intensity of an earthquake i...

Outer Ear Middle Ear
335 wordsWhen Sensing Sound Sensing Sound When we think of hearing, most only consider the outer ear. In reality, the inner ear is the part that does all of the work. The outer ear works as a reverse megaphone, which collects the sounds that we hear and brings them into the inner part of the ear. Ears are located on either side of the head to help with sound localization. Sound localization is how we determine where the different sounds are coming from. The outer ears also help to amplify sounds to diffe...

Nerve Endings Sound Waves
402 wordsWaves Sound Waves Sound Waves Waves are disturbances that travel through a space while changing its matter. A sound wave is what allows us to hear sounds. It is created by vibrations, which are made by the movement of matter. Sound waves must travel through a solid, a liquid, or a gas. The more tight the particles, the faster the wave will travel. This would mean that a sound wave travels fastest through solids and slowest through gases. The speed that it travels through a liquid would come some...
