baselevel

[Footnote: The term "baselevel" is also used to designate the close approximation to sea level to which streams are able to subdue the land.]

McCain and Powell had a slow rise of decades to garner the level of respect that they had achieved…..but in a heartbeat alignment with the baselevel calibration of Bush and Cheney – who, BTW, calibrate lower than 100 which is where pure evil resides – this peak of high spiritual calibration vanishes – never to return in this lifetime.

As streams grow old they approach more and more closely to baselevel, although they are never able to attain it.

While subaerial denudation reduces the land to baselevel, the sea is sawing its edges to WAVE BASE, i.e. the lowest limit of the wave's effective wear.

Usually a river first attains grade near its mouth, and here first sinks its bed to near baselevel.

Since rivers cannot cut their valleys farther below the baselevel of the sea than the depths of their channels, DROWNED VALLEYS are among the plainest proofs of depression.

So long a time is needed to reduce a land mass to baselevel that the process is seldom if ever completed during a single uninterrupted cycle of erosion.

This limit of the level of the sea beneath which they cannot erode is known as baselevel.

In a similar way the surface of a lake in a river's course constitutes for all inflowing streams a local baselevel, which disappears when the basin is filled or drained.
