Why Is Death Valley a Desert?popular definition, desert is a place that receives less than 10 inches of rain a year AND has a high evaporation rate through ground or plants. Amazingly, about third of the Earth's world mass is arid or semi-arid, including many parts of the United States. But what makes Death Valley special is that so much of it is under the sea level, and it's stuck deep between two mountain ranges in a rain shadow from Sierra Nevada mountains. This is why it's one of the hottest and driest regions on Earth currently holding a world record of highest temperature ever recorded (in shade) of 134 degrees Fahrenheit or 54.6 degrees Celsius.
How Cold Does It Get?
Despite the popular image of Death Valley as impossibly hot, it actually gets quite cold in winter. We visited in January, and we most certainly needed sweaters during the day and warm jackets in the evening. We also happened to get an overcast weather during our stay and temperatures never rose above 65 degrees Fahrenheit.
Why Is There Salt in Death Valley?
The ranger also explained a bit about volcanic activity in the region and how Death Valley is still sinking down being pressed between two tectonic plates and at the same time it is filling up with debris from surrounding mountains. It was a great talk that Smarty listened to very attentively.
