Geography and Climate ~Mountains,Deserts,Streams,Rivers,Rain and Snow Most of the mountains in the western region are cold because of altitude. Only some animals can survive on the mountains like mountain sheep.There are wet sides and dry sides of the mountains in the western region.On the dry sides of mountains you can see cactuses. Some of the peaks in the western are really cold; they can be as cold as the north pole.The Rocky Mountain go through the western states.They go through Montana,Wyoming and Utah. The Continental Divide follows the tops of the Rocky Mountains.They also call the Continental Divide the Great Divide. Rivers that are east of the Great Divide flows into the Atlantic Ocean or the gulf of Mexico. Deserts A desert is a place that gets less than 10 inches of snow and rain. North America has 4 main deserts but only 3 of them are in the western.Snow falls at the Great Basin Desert ,it is a cold desert.The Sonoran Desert is the hottest desert in North America. It has been as hot as 117 degrees. The Mojave Desert is also a hot desert,but is smaller than the other deserts in North America. There is another desert called the Kau desert in Hawaii.They call it a desert but it’s not a true desert.There is about 30 inches of rain that falls there every year but is still dry like a desert. Streams In the western states there are many streams. Some of the water that goes to streams is used for electric power and irrigation. Farmers use the water to water their crops.The towns use the water too, for showers,baths,drinking,washing clothes and washing dishes. Other Landforms~Rivers and Lakes~ Nevada~ Most of Nevada’s rivers are small,they only flow through wet season.They flow from December to June. The Virgin and the Muddy river join the Colorado in the Southeastern on the tip of Nevada.The rest of Nevadas rivers go to the Great Basin. During the summer the water evaporates from sinks and it leaves salty mud flats and also dry lakes. The Rocky Mountains~ Wyoming~ The Rocky Mountains sweep across Wyoming in its huge ranges. Some of the ranges extend from the north to the south. In the 1800’s the pioneers had traveled towards the westward on the trails through this area.The Granite Mountains extend eastward from near the southern tip of the wind river range Basin and Range Region~Utah`The Basin and Range Region covers several states. It includes the western part of Utah. It’s one of the driest regions in the United States. Higher ranges plateau are bordering on the east. West and Southwest of the Great Salt Lake is a barren area called the Great Salt Lake Desert.Rain and Snow In the Western mountains the mountains are very important. Mountain ranges in California keeps the rain from falling into deserts.When some air hits the mountains it rises up,as it rises it cools.That’s what causes rain to fall on the other side of the mountain.Then on the other side of the mountain air drops.When the air drops it will make a rain shadow .
