Mass Movement Concepts and Factors

The video tutorial explains how landforms on Earth are shaped by tectonic and erosional forces. It defines erosion, weathering, and deposition, and focuses on gravity as an erosional agent. The tutorial describes various types of mass movements, including creep, rock falls, slides, and slumps, and discusses how water affects these processes. It also covers factors influencing hillside stability and potential triggers for mass movements, emphasizing the importance of understanding these concepts for safety and planning.

What is the process called when rock fragments are physically removed from one location and transported to another?

• Erosion

• Deposition

• Weathering

• Sedimentation

Which force must be overcome for an object to move downhill due to gravity?

• Centrifugal

• Tension

• Compression

• Friction

What is the slowest type of mass movement that involves the gradual downhill movement of soil?

• Slide

• Flow

• Creep

• Slump

What is the term for a rapid mass movement where rocks fall and collect at the base of a cliff?

• Rock slide

• Rock fall

• Creep

• Slump

What type of mass movement occurs when material moves downhill along a curved surface?

• Slide

• Flow

• Slump

• Creep

How does water influence the likelihood of mass movements?

• It increases friction and reduces weight.

• It reduces friction and adds weight.

• It decreases gravity's pull.

• It has no effect.

Which type of mass movement is characterized by high water content causing the material to liquefy and flow?

• Creep

• Slide

• Flow

• Slump

What is a key factor to consider when assessing the stability of a hillside?

• The color of the soil

• The steepness of the slope

• The presence of wildlife

• The amount of sunlight

What can trigger a mass movement on a hillside?

• Walking on flat ground

• Planting trees

• Painting rocks

• Building a house at the top

In which state do mass movements cause the greatest financial and human impact?

• New York

• Florida

• California

• Texas
