Factors Affecting ours Ecoregions Weathering – chemical and physical failure of rocks right into sediment Erosion – the activity of sediment from one location to one more Deposition – the placement of sediment after ~ being carried from place of beginning
You are watching: Piney woods weathering erosion and deposition
CHEMICAL WEATHERING • THE process THAT BREAKS under ROCKS B Y CHEMICAL changes OR REACTIONS.
i. Piney Woods 1. This ecoregion is discovered in southeast Texas. 2. That is the wettest an ar of the state. This permits for a high rate of decomposition to happen resulting in healthy, nutrient-rich soils. 3. The topography is gently rolling to near level through out the region. 4. Pine trees, woody vines, and hardwood trees overcome the vegetation. 1. The is a fire climax system. Fire is important in order for pines come maintain supremacy in the area. 1. Uneven an area has actually been clear-cut of vegetation for construction, the amount of trees and plants have the right to prevent erosion.
ii. Western Gulf coastal Plain 1. Soil in the region is generally sand-based. 2. If there isn’t sufficient vegetation to save the soil in place, rainfall received can cause severe erosion. 3. Catastrophic occasions such as hurricanes can increase tide erosion and deposition.
iii. Blackland Prairie & write-up Oak Savannah 1. These areas have nutrientrich soils and receive great amounts of rainfall through the year. 2. If the land is clear-cut of organic vegetation because that construction, nutrient can quickly be eroded. 3. If the floor is provided for farming and it is not controlled well, nutrients will certainly be quickly used up.
iv. Edwards Plateau 1. This an ar is located in between dry west plains and moist prairies and woods. 2. Unfortunately, erosion has left most of the an ar with an extremely shallow soils (less 보다 10 inches) lined v limestone absent layers. 3. High quantities of rain in a quick amount that time can reason flash flooding.
v. Rolling levels 1. This an ar is component of the an excellent Plains of the main United States. 2. Soils in this area are most fertile and sought after for crop production. 3. Durations of drought and then sudden boost in rainfall causes large amounts the erosion and deplete the soil of nutrients.
vi. Western and also Eastern cross Timbers 1. This is a small, thin region running phibìc to southern on either next of the prairies and plains. 2. The soil is no as susceptible to flooding because it permits water come infiltrate very easily. 3. The an ar is explained as rough, hilly terrain.
vii. High plains 1. “Texas Panhandle” 2. Largest and most totally flat locations of it size in the world! 3. The an ar extends come the Palo Duro Canyon-the nation’s 2 nd biggest canyon. 4. Palo Duro Canyon was formed by water erosion native the Prairie Dog town Fork of the Red River. 5. The water deepens the canyon by relocating sediment downstream. 6. Wind and water erosion progressively widen the canyon.
vii. Southern Texas plains 1. The area is known as “Brush Country” because of the much shorter trees and many shrubs. 2. Overgrazing of the floor has enabled nutrient-rich topsoil to erode way. 3. Rocky, dry soil cannot support grasses, trees have the right to thrive because of your deeper source system.

ix. Trans-Pecos • Rain does not autumn evenly end the area. • “Desert portion” that Texas. • The weathered radical in this area has actually high quantities of calcium. • together a an outcome of erosion and deposition in the area, the soil has high quantities of calcium referred to as caliche.
x. Mountain woodland / West Texas 1. Residence of the tallest mountain in Texas, Guadalupe Peak. Elevation is 8, 749 feet. 2. Pines and also Oaks overcome the tree species. 3. Soils are shallow and rocky. Weathering continues to pat a role in occurring soil and also will for thousands of years come come. 4. Soils in the canyon bottoms and also valleys room deeper together a result of
