The 3 major mountain ranges in the United States are the Pacific ranges and Rocky Mountains in the west and the Appalachian mountains in the east. The Pacific ranges are on the northwestern coast of the United States. The Rocky Mountains are in the western United States but east of the Pacific ranges. They extend all the way from Canada into Mexico and cover 8 states. The Appalachian Mountains are near the East Coast of the United States. They extend from Canada to Alabama. The main difference between the eastern mountain ranges and the western mountain ranges is their ages and heights. The Appalachian Mountain range is the oldest range in the United States. Because of this, the range has faced weathering and erosion, which has worn the mountains down. The highest peaks in the Appalachians are only 6,000 feet. The ranges in the west are much younger and in some cases still growing. The mountains in the west are much higher than those in the east, with peaks over 14,000 ft.
Homo ergaster may have been the first human species to leave Africa and fossil remains show this species had expanded its range into southern Eurasia by 1.75 million years ago. Their descendents, Homo erectus, then spread eastward and were established in South East Asia by at least 1.6 million years ago.Oct 30, 2015
The countries that adopt the International Model Forest Program will benefit from sustainable forest management.
Explanation:
The International Model Forest Program is a program that promotes sustainable forest management, thus the countries that adopt benefit from developing sustainable forest management. This is excellent from several different perspectives, such as:
- recreation
- economy
- ecology
- biodiversity
If the forests are sustainable, than it means that they will be able to prosper, thus maintaining their well being, as well as the well being of the communities of animals and plants in them. Also, this means that there can be economic benefits without destroying the forests, and this can be done by planting new saplings on the places were trees have been cut, and also by gathering forest fruits, herbs, and mushrooms.
The recreation part is too very important. The people will have a beautiful place in nature for recreation, where they can relax and enjoy, have fresh air, and educate themselves about nature first hand.
