Roofs of the World

Mountains are land formations that are useful for people in many ways including forestry, logging, rainfalls, glaciers, rivers, lakes, ponds, tourism, recreation, mountaineering, camping, hiking, skiing, mining and even strategic tactical protection.

Earth�s tallest mountain is Everest at 8,848 m. However, Mount Olympus on Mars holds the record of the tallest mountain in the entire Solar System known to Man (21,171 m).

Interestingly, mountains cover 1/5 of Planet Earth�s terrestrial surface, and occur in 75% of the world�s countries.

Beside the numerous benefits we get from mountains, they can still pose many challenges. For example, mountainous terrain requires more difficult engineering and higher costs to plant infrastructure than on plain ground. The southern European country of Andorra is the sole country in the world which doesn�t have airports, and the reason is that the country�s entire terrain is mountainous, making it unable to receive landings.

Satellites also find it more difficult to peer into mountains than regular crust. Mountains are generally not suitable habitat for agriculture. Higher elevation also witness less protection against Ultra Violet rays and harmful solar radiations, not to mention lower levels of oxygen which, at such altitudes, could cause Acute Mountain Sickness Hypoxia.
