Trail Riding
Trail riding is riding outdoors on trails, bridle paths, and forest roads, but not on roads regularly used by motorised traffic. A trail ride can be of any length, including a long distance, multi-day trip. It originated with horse riding, and in North America, the equestrian form is usually called "trail riding," or, less often "hacking." In the UK and Europe, the practice is usually called horse or pony trekking. The modern term also encompasses mountain biking, mixed terrain cycle-touring, and the use of motorcycles and other motorized all-terrain vehicles. It may be informal activities of an individual or small group, or larger events organized by a club. Some equestrian trail rides in the USA are directed by professional guides or outfitters, particularly at guest ranches, while many equestrians who own horses trail ride on their own in local, state, and national trail systems. In some parts of the world, trail riding (of whatever kind) is limited by law to recognized, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orienteering
Orienteering is a group of sports that require navigational skills using a map and compass to navigate from point to point in diverse and usually unfamiliar terrain whilst moving at speed. Participants are given a topographical map, usually a specially prepared orienteering map, which they use to find control points. Originally a training exercise in land navigation for military officers, orienteering has developed many variations. Among these, the oldest and the most popular is foot orienteering. For the purposes of this article, foot orienteering serves as a point of departure for discussion of all other variations, but almost any sport that involves racing against a clock and requires navigation with a map is a type of orienteering. Orienteering is included in the programs of world sporting events including the World Games (see Orienteering at the World Games) and World Police and Fire Games. History The history of orienteering begins in the late 19th century in Swede ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Plant
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England And Wales
England and Wales () is one of the three legal jurisdictions of the United Kingdom. It covers the constituent countries England and Wales and was formed by the Laws in Wales Acts 1535 and 1542. The substantive law of the jurisdiction is English law. The devolved Senedd (Welsh Parliament; cy, Senedd Cymru) – previously named the National Assembly of Wales – was created in 1999 by the Parliament of the United Kingdom under the Government of Wales Act 1998 and provides a degree of self-government in Wales. The powers of the Parliament were expanded by the Government of Wales Act 2006, which allows it to pass its own laws, and the Act also formally separated the Welsh Government from the Senedd. There is no equivalent body for England, which is directly governed by the parliament and government of the United Kingdom. History of jurisdiction During the Roman occupation of Britain, the area of present-day England and Wales was administered as a single unit, except f ...
