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

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.

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

California Landforms
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

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

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