1 Lesson 10.2: The Louisiana Purchase and Exploration Today’s Essential Question: What was the importance of the purchase and exploration of the Louisiana Territory?

2 Vocabulary surplus – more than what is needed or used nomadic – moving from place to place, without a permanent home expedition – a journey of exploration headwaters – where a river begins

3 Check for Understanding What is today’s essential question? What do some people do with their surplus clothing? What are some people or animals that might be described as nomadic? What is an expedition that you would like to be part of? Which direction would you go to find any river’s headwaters?

7 As Americans moved west, they entered three distinct geographic regions.

8 Trans- Appalachia Wooded; rolling hills and flatlands Well-watered Humid summers, cold winters Settlers by the thousands moving in, displacing the Native Americans

9 The Great Plains Flat, rolling plains Rocky Mountains Great Basin (desert) Treeless; few rivers Hot, dry summers; bitterly cold winters France and Spain Nomadic Plains Indians (horse culture) Non-migratory Indians in the Southwest

10 The Pacific Coast Mild weather; rainy in the Northwest, dry in the Southwest Sierra Mountains, Cascades, Coast Ranges, Central Valley Many natural harbors Spain, Russia, Britain, the United States in competition Many Indian groups of various cultures
