MOUNTAINS OF NORTH AND SOUTH AMERICA AND MEXICO

 
  1. Mountains are usually formed at convergent tectonic plate boundaries when two plates move toward one another, and an upheaval (a mountain range) results.
  2. Tectonic plates press against each other, which causes the land to rise into a mountainous form.
  3. When the mountains stop forming, that boundary changes to a rift.
  4. Mountains play a significant role in providing water and food to millions of people worldwide.
  5. Mountains cover around 22 percent of the surface of the Earth.
  6. The Andes are the world’s most extended above-water mountain range. The range stretches from North to South in South America. They run through 7 countries:  Venezuela, Columbia, Ecuador, Peru, Bolivia, Chile, and Argentina.
  7. The Himalayas are one the youngest mountain ranges.
  8. Rocks and fossils are dated by using a carbon dating procedure. It is a radiometric dating method based on the natural radioactive decay of certain elements, such as potassium and carbon.
IT’S www.vernbender.com GETTING BEYOND EVIL IS A START NAME THE MOUNTAINS  The mountain systems of the Earth are characterized by a tree structure, where mountain ranges can contain sub-ranges. The sub-range relationship is often expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains. Equivalently, the Appalachians are the parent of the White Mountains and the Blue Ridge Mountains, and the White Mountains and the Blue Ridge Mountains are children of the Appalachians. The parent-child expression extends to the sub-ranges themselves: the Sandwich Range and the Presidential Range are children of the White Mountains. At the same time, the Presidential Range is a parent to the Northern Presidential Range and Southern Presidential Range. Alaska Range   VERN BENDER     VERN BENDER          VERN BENDER
