Weathering Environments Part 1: Fluvial Processes

The video tutorial explores various weathering environments, focusing on fluvial, aeolian, and glacial processes. It delves into the dynamics of sediment transport in streams, highlighting the roles of saltation and traction. The tutorial also covers mass wasting, including creep and landslides, and discusses the impact of mud and debris flows, particularly lahars, during volcanic eruptions.

What determines whether a weathering environment is depositional or erosional?

• The type of sediment present

• The presence of vegetation

• The energy level of the environment

• The temperature of the environment

In fluvial environments, what primarily influences the water velocity?

• The type of sediment

• The slope of the land

• The amount of rainfall

• The temperature of the water

What is the main factor that affects a stream's ability to transport sediment?

• The depth of the stream

• The temperature of the water

• The diameter of the sediment

• The color of the sediment

Which process involves sediment bouncing along the stream bed?

• Traction

• Suspension

• Erosion

• Saltation

What is the term for the slow and steady movement of soil downhill?

• Landslide

• Creep

• Erosion

• Avalanche

What event can trigger a landslide?

• A drought

• An earthquake

• A sunny day

• A cold front

What is a lahar?

• A volcanic mudflow

• A type of rock fall

• A type of debris flow

• A type of landslide
