Geo midterm 3.2

Hydrology and Landscape Denudation

• A topographic low spot on the landscape where water spills over when the lake or pond reaches a sufficient depth is called a spillway.
• When sediment or soil is upthrust due to the freezing of wet soil beneath, it is called frost heave.
• The concentration of natural drainage channels or streams within a given geographic area is referred to as drainage density.
• When two streams of the same order merge, the new stream is identified by increasing the stream order by one.
• The most common type of drainage system on the landscape is dendritic.
• The volume of discharge at any given place and time that is solely the product of groundwater seepage into the stream or river is called base flow.
• The frequency of a flood event and its magnitude is known as flood regime.
• Weathering and mass movement are two major components of landscape denudation.
• Perennial streams are streams with water flowing in them all year long, not ephemeral streams.
• Different weathering processes often act together.

Test your knowledge on hydrology terminology by answering questions related to water bodies and their behaviors. Identify the term used when the water level in a lake or pond reaches a sufficient depth and spills over at a low spot on the landscape.
