Van Allen belt Van Allen belt. n. (Physical Geography) either of two regions of charged particles above the earth, the inner one extending from 2400 to 5600 kilometres above the earth and the outer one from 13 000 to 19 000 kilometres. The charged particles result from cosmic rays and are trapped by the earth's magnetic field.

Serpentine/Drive Belt Replacement Service The serpentine/drive belt or v-belt is a rubber belt that connects the alternator, power steering, and AC to the part of the engine (crankshaft) which transfers the power from the engine to those components. Without this belt, the battery will not get charged and none of the electrical accessory components in the car will work.

Volksmarching (October 2009) (Learn how and when to remove this template message) Volksmarching (from German Volksmarsch, people's march) is a form of non-competitive fitness walking that developed in Europe. Participants typically walk 10 kilometers (6.2 mi) on an outdoor path. Volksmarching associations offer incentive awards (usually pins and patches) for participating in a certain number of events. Volksmarching participants enjoy recording distances and event participation in international record books.

- The way on which solar wind 'plasma' invades the Earth's magnetic field and seeps into the inner regions where the van Allen radiation belts are located, is not very well known. Also, in the direction opposite the Sun, the Earth's magnetic field is pulled way out into interplanetary space making it look like a comet.ll of this is made much more violent by the solar wind, especially the storm clouds that the Sun launches our way from time to time!

- The Sun Belt is a region of the United States generally considered to stretch across the Southeast and Southwest. Another rough definition of the region is the area south of the 36th parallel. The main defining feature of the Sun Belt is its warm climate, with extended summers and brief, relatively mild winters.

Sun Belt Sun Belt or Sunbelt, southern tier of the United States, focused on Florida, Texas, Arizona, and California, and extending as far north as Virginia. The term gained wide use in the 1970s, when the economic and political impact of the nation's overall shift in population to the south and west became conspicuous.

Chapter Six Vocabulary A material in which the total strain developed has elastic and viscous components. Part of the total strain recovers similar to elastic strain. Some part, though, recovers over a period of time. Examples: polymer melts, many polymers (Silly Putty). The term anelastic is used for metallic materials.

Van Allen radiation belt Van Allen Radiation Belt. The term Van Allen belts refers specifically to the radiation belts surrounding Earth; however, similar radiation belts have been discovered around other planets. The Sun itself does not support long-term radiation belts, as it lacks a stable, global dipole field.

Schatzki ring A Schatzki ring or Schatzki–Gary ring is a narrowing of the lower esophagus that can cause difficulty swallowing (dysphagia).The narrowing is caused by a ring of mucosal tissue (which lines the esophagus) or muscular tissue. Schatzki ring is usually diagnosed by esophagogastroduodenoscopy or barium swallow. Endoscopy usually shows a ring within the lumen of the esophagus which can be of variable size (see picture).

Van der Waals force Van der Waals force. Van der Waals forces include attraction and repulsions between atoms, molecules, and surfaces, as well as other intermolecular forces. They differ from covalent and ionic bonding in that they are caused by correlations in the fluctuating polarizations of nearby particles (a consequence of quantum dynamics[5]).

Van Allen radiation belt Van Allen radiation belt. A radiation belt is a layer of energetic charged particles that is held in place around a magnetized planet, such as the Earth, by the planet's magnetic field. The Earth has two such belts and sometimes others may be temporarily created. The discovery of the belts is credited to James Van Allen, and as a result the Earth's belts are known as the Van Allen belts. The main belts extend from an altitude of about 1,000 to 60,000 kilometers above the surface in which region radiation levels vary.

What Is The Kuiper Belt? The Kuiper Belt (also known as the Edgeworth–Kuiper belt) is a region of the Solar System that exists beyond the eight major planets, extending from the orbit of Neptune (at 30 AU) to approximately 50 AU from the Sun. It is similar to the asteroid belt, in that it contains many small bodies, all remnants from the Solar System’s formation.

The Hotly Contested History of the Seat Belt A Federal Motor Vehicle Safety Standard proposes that all vehicles made after January 1, 1973, include an automatic restraint system, i.e., air bags or automatic belts. The auto industry, knowing that it would have to increase production costs to meet the new standard, balks, leading to a decade of argument and delay.
