Highlands or uplands are areas of high elevation such as a mountainous region, elevated mountainous plateau or high hills. Generally, upland refers to a range of hills, typically from 300 m (980 ft) up to 600 m (2,000 ft), while highland is usually reserved for ranges of low mountains. However, the two terms are interchangeable and also include regions that are transitional between hilly and mountainous terrain. (Full article...)

A dome is a feature in structural geology where a circular part of the Earth's surface has been pushed upward, tilting the pre-existing layers of earth away from the center. In technical terms, it consists of symmetrical anticlines that intersect each other at their respective apices. Intact, domes are distinct, rounded, spherical-to-ellipsoidal-shaped protrusions on the Earth's surface. A slice parallel to Earth's surface of a dome features concentric rings of strata. If the top of a dome has been eroded flat, the resulting structure in plan view appears as a bullseye, with the youngest rock layers at the outside, and each ring growing progressively older moving inwards. These strata would have been horizontal at the time of deposition, then later deformed by the uplift associated with dome formation. (Full article...)

The figure-eight knot or figure-of-eight knot is a type of stopper knot. It is very important in both sailing and rock climbing as a method of stopping ropes from running out of retaining devices. Like the overhand knot, which will jam under strain, often requiring the rope to be cut, the figure-eight will also jam, but is usually more easily undone than the overhand knot.

The stevedore knot is an extension of simple figure-eight knot with an additional turn before the end is finally tightened. (Full article...)

Ski jumping is a winter sport in which competitors aim to achieve the farthest jump after sliding down on their skis from a specially designed curved ramp. Along with jump length, competitor's aerial style and other factors also affect the final score. Ski jumping was first contested in Norway in the late 19th century, and later spread through Europe and North America in the early 20th century. Along with cross-country skiing, it constitutes the traditional group of Nordic skiing disciplines.

The ski jumping venue, commonly referred to as a hill, consists of the jumping ramp (in-run), take-off table, and a landing hill. Each jump is evaluated according to the distance covered and the style performed. The distance score is related to the construction point (also known as the K-point), which is a line drawn in the landing area and serves as a "target" for the competitors to reach.
