  2. Mount Thor - Wikipedia

    en.wikipedia.org/wiki/Mount_Thor

    The mountain is located 46 km (29 mi) northeast of Pangnirtung and features Earth's greatest vertical drop of 1,200 m (4,100 ft), with the cliff overhanging at an average angle of 105 degrees (15 degrees from vertical). [6] Despite its remoteness, this feature makes the mountain a popular rock climbing site. Camping is allowed, with several ...

    The point on the surface of Earth's crust closest to the Earth's centre (interpreted as a land surface or sea floor) is the bottom of Litke Deep, in the Arctic Ocean, at 6,351.7043 km (3,947 mi) from Earth's centre; the deep's depth relative to sea level is 5,449 m (17,877 ft).

    The factors that have been used for landslide hazard analysis can usually be grouped into geomorphology, geology, land use/land cover, and hydrogeology. Since many factors are considered for landslide hazard mapping, GIS is an appropriate tool because it has functions of collection, storage, manipulation, display, and analysis of large amounts ...

    This is commonly regarded as being the largest vertical drop on Earth [4] at 1,250 metres (4,100 ft). The sheer north face of Polar Sun Spire, Baffin Island, rises 4,300 ft above the flat frozen fjord, although the lower portion of the face breaks from the vertical wall with a series of ledges and buttresses.

    The following sortable table lists land surface elevation extremes by country or dependent territory. Topographic elevation is the vertical distance above the reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface.

    The original calculations assumed that the Earth has the same density throughout - and the gravitational force changes as you approach the center, much like the weight of a spring that bounces up ...

  8. Cliff - Wikipedia

    en.wikipedia.org/wiki/Cliff

    For example, given a truly vertical rock wall above a very steep slope, one could count just the rock wall or the combination. Listings of cliffs are thus inherently uncertain. Some of the largest cliffs on Earth are found underwater. For example, an 8,000 m drop over a 4,250 m span can be found at a ridge sitting inside the Kermadec Trench.
