1.75 m – (5 feet 8 inches) – height of average U.S. male human as of 2002 (source: U.S. CDC as per female above) 2.4 m – wingspan of a mute swan; 2.5 m – height of a sunflower; 2.7 m – length of a leatherback sea turtle, the largest living turtle; 2.72 m – (8 feet 11 inches) – tallest-known human (Robert Wadlow) [31]
Mauna Loa (4,169 m or 13,678 ft) is the largest mountain on Earth in terms of base area (about 5,200 km 2 or 2,000 sq mi) and volume (about 42,000 km 3 or 10,000 cu mi), although, due to the intergrade of lava from Kilauea, Hualalai and Mauna Kea, the volume can only be estimated based on surface area and height of the edifice.
(Some people have claimed there are six more 8,000m peaks in Nepal, making for a total of 20. [1]) All are in the two highest mountain ranges in the world, the Himalayas and the Karakoram. Mount Everest - 8,848 m (29,029 ft) K2 - 8,611 m (28,251 ft) Kanchenjunga - 8,586 m (28,169 ft)
Kincheloe flew 2000 miles per hour (3,200 km/h) at 126,000 feet (38,500 m), or 24 miles up. At this altitude and speed, aerodynamic lift still carries 98 percent of the weight of the plane, and only two percent is carried by inertia, or Kepler force , as space scientists call it.
When each equatorial degree was divided into 18 leagues, the geographical mile was equal to 1 / 54 degree or about 2.06 kilometres (1.28 mi); when divided into 20 leagues, the geographical mile was equal to 1 / 60 degree, approximating the values provided above; and when divided into 25 leagues, the geographical mile was equal ...
Winds commonly attain 160 km/h (100 mph); [90] in February 2004, a wind speed of 280 km/h (175 mph) was recorded at the summit. These winds can hamper or endanger climbers, by blowing them into chasms [ 90 ] or (by Bernoulli's principle ) by lowering the air pressure further, reducing available oxygen by up to 14 percent.
Earth radius (denoted as R 🜨 or R E) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid (an oblate ellipsoid), the radius ranges from a maximum (equatorial radius, denoted a) of nearly 6,378 km (3,963 mi) to a minimum (polar radius, denoted b) of nearly 6,357 km (3,950 mi).
The bottom of the crater is 100–130 m (330–430 ft) in diameter. Slope angles from the crater to a distance of 1.5–2 km (0.93–1.24 mi) are 31°–35°, the angle of repose for dry gravel. Beyond this distance, slope angles are about 27°, which is caused by an increase in scoria .
