Forces inside and outside Earth produce Earth’s diverse landforms. 2.1 Landforms Landforms are features such as mountains, plateaus, and plains. 3

Uplift Is any process that moves the surface of Earth to a higher elevation –Mountains and plateaus are a result of uplift. 2.1 Landforms Earth’s internal energy produces uplift. When melted rock moves to the surface, a mountain called a volcano can form. 2

Landforms Shaped by Surface Processes Surface processes wear down the land. Weathering and erosion Most erosion is done by water (p. 78) 2.1 Landforms 1

California Landforms

Yosemite Valley National Park –Glaciers carved the U-shaped surface of the valley 2.1 Landforms Lassen Volcanic National Park –Features an active volcano –Part of Cascade Mountain Range –Shaped by Earth’s internal forces 4

Mt. Shasta –Cone-shaped volcano formed by sudden uplift Mountains of California Sierra Nevada and Costal Ranges –Formed by plate tectonic forces –Are evidence of slow uplift 2.1 Landforms 3

Valleys Some valleys are flat, nutrient rich land located next to mountain ranges. Some valleys are extremely important to agriculture. 2.1 Landforms 2

Beaches Are temporary features Require constant sediment deposits from rivers Without rivers continuously adding more sand, beaches would disappear. (p. 81) 2.1 Landforms 1
