Unit 10 Geologic Processes on Earth’s Surface

Weathering and Erosion

• Weathering is the process that refers to the breaking down of rocks into smaller pieces called sediments.
• Sediments are compacted and cemented to form sedimentary rocks.

Rock Transformation

• Metamorphism is the geologic process that involves the change in form in mineral assemblage and texture of rocks.

Landforms and Wonders

• The Underground River, one of the new seven wonders of nature, is located in a city.

Demonstrating Weathering

• Water, ice, and salt can be used to demonstrate weathering by water in a simple experiment.

Geologic Processes

• Denudation is the process that involves rocks being turned into sediments, transported through different media, and eventually deposited in riverbanks and shorelines.
• Weathering is responsible for creating several spectacular landforms through slow yet constant surface processes.

Transportation of Rocks

• Erosion is the geologic process that involves the breakdown of rocks into smaller particles and their transportation to new locations.

Weathering Process

• Weathering is the process by which rocks are physically and chemically broken down into smaller particles.

Landslides

• Landslides are the process that involves the sudden movement of a large mass of earth or rock down a slope.
