What is the title of this map? (Ecoregions of Texas) What two words are joined together to create the word ecoregion? (ecological + region = ecoregion) What is the root word for ecological? (ecology) What does ecology mean? (Ecology is the study of the environment. This includes the study of the interactions of living organisms with their natural environment.)
What does region mean? (A region is an area of land.) What do you think ecoregion means? (the study of the environment of a particular area of land) How many ecoregions are shown on this map? (eleven)
A. Locate the Piney Woods ecoregion on the map. Color the area green and label the ecoregion. B. Repeat the step for the Gulf Coast Prairies and Marshes (blue), the Edwards Plateau(tan),Llano Uplift (yellow), the High Plains (orange), and the Trans Pecos(grey),etc. until you have completed coloring the map and key. Use the next slide to help you.
Look at the next two maps and identify patterns. Be prepared to share what you notice.
Which part of Texas is coldest in January? Which part of Texas is warmest in January?
Which part of Texas is coolest in July? Which part of Texas is hottest in July? Which part of Texas has the biggest changes in temperature from season to season? Which part of Texas has the least change in temperature from season to season? Record information.
Why analyze the data of these two months when studying the environments of the Texas ecoregions? (January is in winter. July is in summer. An inference could be made that these two months show the extremes in temperature—coldest and hottest.) What valid conclusion can be drawn from the data represented in these maps? (The northern and northwestern areas of the state have a wide range in temperature. The summers are hotter and the winters are colder than the southern and southeastern areas of the state. On average, the temperatures of the southern and southeastern areas of the state are less extreme.)
What does Precipitation mean? What patterns of precipitation does this map show?
Do all the ecoregions receive the same amount of precipitation? Justify your answer. (No. The map is shaded in different colors to indicate the amount of rainfall an area receives according to the map key. ) Why is East Texas shaded green and West Texas shaded brown? (In general, East Texas receives more rain than West Texas.)
Satellite Map of Texas Showing Evidence of Plant Growth Why is East Texas shaded green and West Texas shaded brown? Why is central Texas shaded yellow? Which two ecoregions generally receive the most rainfall? Which two ecoregions generally receive the least rainfall?
Which two ecoregions generally receive the most amount of precipitation? (ecoregions 1— Piney Woods and 4—Gulf Coast Prairies and Marshes) Which two regions generally receive the least amount of precipitation? (ecoregions 10—High Plains and 11—Trans Pecos/Chihuahuan) Record information about Annual Precipitation for each ecoregion.
How does precipitation affect soil? (The greater/more frequent the precipitation, the moister the soil; lesser precipitation results in a drier soil.) How does precipitation affect plants? (The greater/more frequent the precipitation, the greater the number and types of plants; lesser precipitation the fewer the number and types of plants.) What is the role(s) of plants in a particular environment? (hold soil in place to prevent erosion, provide food for animals, shelter/habitat)
What are some characteristics of the Piney Woods ecoregion? (tall pine trees, swamp, maple trees, sandy soil, shrubs, broad-leaved plants, grasses, etc.) What are some characteristics of the Gulf Coast Plains and Marshes/Coastal Sand Plains ecoregions? (barrier islands, marshes, flat plains, grasses, etc.)
The pink area centered below represents the igneous rock Granite that is found in the Llano Uplift.
What are some characteristics of the Edwards Plateau/Llano Uplift ecoregion? (Enchanted Rock—a dome of granite, canyonlands, streams, deciduous forests, etc.) What are some characteristics of the High Plains ecoregion? (hills, mountains, short grasses, not as many trees) What are some characteristics of the Trans Pecos ecoregion? (mountain ranges, desert, desert valleys, cactus, etc.)
