3. High Places What are the differences between hills… These are the Clay Hills in West Texas. Trees can grow at their tops and they would be easy to climb. … and mountains? K2, the world’s second highest mountain
4. Glaciers As the snow collects over many years, an ice field forms. Ice flows down the valleys and slopes of the mountains to the lower elevations, and glaciers are born.
5. Glaciers spread and recede
6. Alaska glaciers Glaciers in Alaska’s Denali National Park.
7. Continental Divide A series of mountain ridges extending from Alaska to Mexico that forms the watershed of North America. Most of it runs along peaks of the Rocky Mountains and is often called the Great Divide in the United States.

9. Relief map of the world’s mountain ranges
10. How are mountains formed? Fold mountains are caused by the pressure of two plates compressing upwards and downwards to create mountain ranges such as the Himalayas.
11. Mt. Everest At 29,048 ft., Mt. Everest in the Himalayan range is the world’s highest peak. As of 2002, almost 1,500 people have stood on the summit and 173 climbers have died trying.
12. The Himalayas Mountains like the Himalaya Range of Tibet resulted from the collision of the continents. About 50 millions years ago moving tectonic plates brought the continents of Asia and India into contact with one another.
13. Mauna Loa rises 16, 400 ft. from the sea floor giving it a total height of 30,080 ft. Mauna Loa – World’s tallest mountain
14. V-shaped valleys become U-shaped valleys As glacial ice squeezes into V-shaped river valleys from the upper mountains, the grinding rock-filled ice carves out the valley bottom. After the ice melts away, the valley appears U-shaped.
15. The Appalachian mountain chain was once much taller, but the forces of erosion have reduced them to “hills” by most definitions. The part of that chain is known as the Alleghenies in western New York. Appalachian “Mountains”

17. Only one in ten days are clear of rain on this side of Mt. Rainier
19. Rain shadow This area on the side of Washington State’s Mt. Rainier is sheltered from prevailing winds and rain-bearing clouds, resulting in relatively dry conditions.
