How does weathering affect the topography of each Texas eco-region?
It reshapes the topography and gives each eco-region unique landforms.

What does deposition do to harm the many different eco-regions of Texas?
It lays down sediment in areas which block off supporting streams.
100
How has erosion affected the Llano uplift eco-region?
It has carried away the broken down granite of the area.

What is the difference between physical and chemical weathering?
Physical weathering is the physical breaking down of rock were as chemical weathering is the breaking down of rock due to chemical changes.
