Texas Ecoregions
Directions: Answer the following questions using the transparency of the ecoregions and the
laminated data maps.
1. Do all of the ecoregions receive the same amount of precipitation?
2. Why is East Texas shaded green and West Texas shaded brown?
3. Which two ecoregions generally receive the most amount of precipitation?
4. Which two regions receive the least amount of precipitation?
5. How many different soil types does Texas have?
6. Do you think rain amounts can effect soil type?
7. In general, describe the January temperatures in Texas.
8. In general, describe the July temperatures in Texas.
Directions: Complete the fact sheet for each ecoregion. First, color in the correct
region the same color as the map on page 1. When filling in the information,
make sure you use correct units (inches, feet, ⁰C etc…)
