Warm-Up
• Get out Concept Map & Grading Utensil
• Define and give an example of each
– Weathering
• Chemical
• Physical/Mechanical
– Erosion
– Deposition
Warm-Up
• Define and give an example of each
– Weathering
– Breaking of rock into sediments
• Chemical
– Change in chemical composition (color is evidence)
– Oxidation/rusting, acids
• Physical/Mechanical
– Change in physical properties (shape/size)
– Abrasion, Ice wedging, Roots wedging, animal burrowing
– Erosion
• Movement of sediment
• Wind, Water, Gravity, Glacier/Ice
– Deposition
• Dropping/dumping of sediment in a new location
• Sand dunes, beaches, mountains, river deltas
Today’s Tasks
• Tape in WED & EcoRegion Big Idea Notes
• Turn in Concept Map
• Get Test grade
– Sign up for tutoring if you need it
• EcoRegion Map & Characteristics
EcoRegion Chart
Major Cities
1. Use Temperature & Precipitation Maps to locate 7
major cities.
– Nacogdoches, Lubbock, Dallas, Brownsville, Houston, El
Paso, Austin
2. Place the name of the city in the appropriate
EcoRegion on the chart.
– South Texas Plains does not have a city
– Gulf Coast has 2 cities
3. Now add: Galveston, Fort Worth, Laredo, Amarillo
– Next slide has a map of city locations
– Now ever EcoRegion should have at least 1 city, some will
have more
Temperature & Precipitation
• Use the colored maps on the slides that follow to
figure out the next 3 columns…
– Average Temperature in July oF
– Average Temperature in January oF
– Average Yearly Precipitation (Inches/Year)
• Some EcoRegions have more than one answer. So
include a range (lowest – highest), like 70 -100oF
Warm-Up
• Which ecoregion would the following W.E.D.
most likely happen in?
– Wave erosion
– Limestone caves
– Sand dunes
Warm-Up
• Which ecoregion would the following W.E.D.
most likely happen in?
– Wave erosion
– Limestone caves
– Sand dunes
Today’s Goal
• Today I will complete the
–EcoRegion Chart & Map.
• So we can show that we can..
–Identify W.E.D. that happens in
ecoregions of Texas.
–Locate ecoregions of Texas on a map.

This is the MOST IMPORTANT section
Different EcoRegions experience weathering, erosion, and deposition differently.
Place examples of WED in the appropriate EcoRegion, use as many times as indicated in ()
– Mechanical Weathering: by roots wedging (lots of plants/vegetation)
– Mechanical Weathering: by sand abrasion (windy & sandy)
– Chemical Weathering: Limestone Caves
– Chemical Weathering: Occurs most often here b/c of High temperature & Moisture
levels
– Weathering & Erosion: by farming
– (4) Weathering & Erosion: by many rivers
– (4) Erosion: by Gravity due to elevation differences
– Erosion: by Ocean waves
– Erosion: Happens faster b/c less plants (vegetation)
– Erosion: Happens slow b/c dense plants (vegetation)
– Deposition: Mountains
– Deposition: Beaches
– Deposition: Sand Dunes
– Deposition: River Deltas
EcoRegion Map
Color code each EcoRegion a different color.
Identify the color you used in the Key / Legend.
You should be able to label a blank EcoRegion
map in the future.

1. Identify the
EcoRegions of
Texas by placing
the numbers in
the chart.
2. Identify 3 W.E.D.
events that
happen in the
ecoregion(s) of
your choice.
