Ecoregions in Texas

1
Ecoregions in Texas

• Defined by weathering, erosion, deposition
  forming a variety of landforms (such as beaches,
  plateaus, mountains and canyons) and soil types
  (fertile, clay rich, sandy)
• The combination of topography, soil and climatic
  conditions have formed 10 different regions in
  Texas

Water is an agent of weathering and erosion

• The precipitation trend goes from wet to dry when
  moving from the east part of Texas to the west
  part.
• So eastern ecoregions will have more signs of
  water erosion/deposition than western ecoregions.

The temperatures can affect the type of vegetation

WEATHERING

• The breaking down of rock by physical or chemical
  means wind, ice, plants, water, gravity, oxygen,
  carbon dioxide, other rock particles, animals.

9
EROSION

• The movement of rock particles by wind, water,
  ice or gravity

10
DEPOSITION

• The dropping of sediment

Each Ecoregion is unique in

• Amount of precipitation
• Soil
• Vegetation
• Elevation
• Topographic features
• Agents of weathering and erosion
