Landslides Due to the Melting of Permafrost ____

question 33

Multiple Choice

Landslides due to the melting of permafrost ____.

• A)are shallow and only affect a few meters as the thawed layer slides off the remaining permafrost
• B)create rotational slumps as deeper thawed areas loosen the connection of permafrost to the supporting layers
• C)are extensive and damaging, where lakes and streams warm the ground
• D)create large translational slumps as unthawed permafrost slides over subsurface meltwater
• E)can be avoided if vegetation maintains a deep snow cover

Definitions:

Hydraulic Circuits

Networks designed to use hydraulic fluid to transmit energy from one component to another within a hydraulic system.

Area Multiplied

The process of calculating the extended surface or space by multiplying dimensions, typically used in geometric calculations.

Work

When effort or force produces an observable result (movement), work results. In a hydraulic circuit, this means moving a load. To produce work in a hydraulic circuit, there must be flow. Work is measured in units of force multiplied by distance, for example, pound-feet.

Confined Hydraulic Circuit

A closed hydraulic system where the fluid is contained within specific boundaries, often used for precise control in machinery.
