Water and Rocks

Let's look at forms seen as a result of The Water Cycle and Weathering Cycles.  I define the water cycle as "where water goes: evaporation forming clouds to falling, freezing, and running over and through the ground.

 A huge form in Texas is the Ogallala Aquifer and it isn't even visible!  Aquifers are basically underground pools of water.  The Ogallala Aquifer stretches from Texas through Nebraska.  Many people rely on this as a main source for water.

Water running all the way from the top of the Rocky Mountains seeps through the ground and fills this Aquifer

A little further south lie the artesian San Solomon Springs.  They feed a huge swimming pool that is home to catfish, turtles, and other plants and animals.  I visited this pool as a teenager, learned to snorkel, and have always dreamed of returning.

Artesian Springs are springs that are connected to an underground water source and flow from their own pressure.  They don't need a pump or a bucket.

Another key sight in Texas is the Red River.  It mostly creates the border between Texas and Oklahoma.  The river collects in reservoirs for man's use as well as feeds into the Mississippi River.  

The Red River clearly displays the streamflow aspect of the water cycle: it's a flowing stream.  Also, it is a major tributary of contributing stream feeding into a larger stream.  These are both aspects of the water cycle.

Moving on to weathering (the breaking down of rocks in place), let's look at Lighthouse Rock in Palo Duro Canyon.  This rock shoots into the sky in the second largest canyon in the USA.  People visit to view this rock, the canyon, and a musical.

Weathering plays a huge roll in the current shape of this rock.  There are joints (cracks in the rock)  which allow for  frost weathering to occur.  Also, the white colors and odd shape give evidence to salt weathering (salt literally breaking down the rock).  Below it looks like rock also sloughed off of the larger, solid piece above.
