question 25

Multiple Choice

What will the long term effect of mass wasting be on oversteepened slopes?

• A) It will fill in the lowland up to the level of the surrounding highland region.
• B) It will perpetuate catastrophic mass failures until the entire highland region is removed
• C) It will eventually restore an equilibrium profile by reducing the slope angle.

Definitions:

Resting Potential

The voltage difference across the neuron's plasma membrane when it is not transmitting a signal, providing the neuron with the potential energy needed for activation.

Voltage Gradient

Difference in charge between two regions that allows a flow of current if the two regions are connected.

Concentration Gradient

Difference in the relative abundance of a substance among regions of a container; allows the substance to diffuse from an area of higher concentration to an area of lower concentration.

Diffusion

The movement of molecules from an area of higher concentration to an area of lower concentration, a fundamental process in biology and chemistry.
