What made the Great Plains difficult to settle?
Water shortages – low rainfall and few rivers and streams meant there was not enough water for crops or livestock. Few building materials – there were not many trees on the Great Plains so there was little timber to use for building houses or fences. Many had to build houses out of earth.

How do plains affect climate?
Because the Great Plains extend the entire north-south length of the United States, the region experiences a wide range of seasonal and average annual temperatures. Higher temperatures lead to greater evaporation and surface water losses, more heat stress, and increased energy demand for cooling.
What are the negative effects of mountains?
Challenges affecting mountain ranges The more people living in mountain areas, the more threats to native wildlife. Increased livestock on the alpine meadows leads to wild species living there being pushed further into the high mountains, and increasing the risk of predators preying on domestic livestock.
