You know that Mt. Erin is more than 350 m above sea level because the mountain has been measured and mapped. You can find the information regarding elevation on most maps.
Discovery is NASA's oldest space shuttle and it has been in flight for more than 25 years. Currently, it has traveled 148,221,675 miles.
Not by people.Exploratory space vehicles carrying robotic scientific instrumentation and communications equipment have surveyed Mars from orbit, and have landed and explored its surface. But there has been no "manned" (peopled) voyage to that planet.A NASA program has been proposed that could lead to a manned landing on Mars some time after 2020; but the chances of it being adopted are considered slim, mainly because of budgetary considerations.
Tornadoes can vary greatly in size, with most being around 50 to 100 meters wide. The largest tornadoes on record have been over 2 miles wide and can stay on the ground for over 100 miles. These are very rare and extreme cases.
The greatest distance a tornado is recorded to have traveled is 219 miles.

As of the latest data, over 1,000 miles of passage have been mapped and surveyed in the extensive cave systems around the world, particularly in areas like the United States. This includes significant cave networks such as Mammoth Cave in Kentucky, which is one of the longest in the world. Ongoing exploration and advancements in technology continue to expand our understanding of these subterranean environments.
With more than 350 miles of surveyed passageways, Mammoth Cave is at least 3 times longer than any cave known. How long might it be? Geologists estimate that there could be as many as 600 miles of yet undiscovered passageways.
* Stalactites grow from the top down. * Stalagmites grow from the bottom up. * When they join you have a column. The other forms of speleothems include: * Flowstone * Dripstone * Anthodites * Helicites * Chandeliers * Straws and * Draperies Cave popcorn, snotties and cave pearls also exist and 10 mm cave pearls and larger are special finds for speleologists,
