The average age of a first-home buyer increased from 25 in the 1970s to 31, according to analysis by Genworth in 2011. This is expected to grow as soaring prices prevent a growing number of young buyers from entering the market.
A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism.he highest point in San Francisco, California, is called Mount Davidson, notwithstanding its height of 300 m (980 ft), which makes it twenty feet short of the minimum for a mountain by American designations. Similarly, Mount Scott outside Lawton, Oklahoma is only 251 m (823 ft) from its base to its highest point.
A mountain range (mountain chain, mountain belt) is a geographic area with many mountains. A 'mountain system' or 'system of mountain ranges' includes geological features that are in the same region as a mountain range.Mountain ranges usually include highlands or mountain passes and valleys.Individual mountains in the same range do not always have the same geology or petrology.ountain ranges outside of these two systems include the Arctic Cordillera, the world's northernmost mountain system. If the definition of a mountain range includes underwater mountains, then the ocean ridges form the longest continuous mountain system on Earth, with a length of 65,000 kilometres (40,400 mi).
