The Gulf Prairies and Marshes ecoregion experience significant soil erosion. One would expect the climate in this region to be –

• dry and hot.
• cold and snowy.
• wet and rainy.
• warm and humid.

In Galveston, the beaches are often exposed to hurricanes originating in the Gulf of Mexico. It is reasonable to predict that hurricane activity may...

• create new rivers near Galveston
• move sand from the beach to offshore sand bars
• cause local earthquakes after the storm
• create new river deltas along the beaches

The Edwards Plateau has limestone and granite that go through oxidation and rust. What type of weathering is this?

• Physical Weathering

• Chemical Weathering

• Biological Weathering

• Mechanical Weathering

Which ecoregion of Texas is most likely to be most affected by wind erosion creating sand dunes and does receive rain, it can lead to flash floods, which can weather and erode the rocks and sediment.

• Region 4 Gulf Coast Prairies and Marshes
• Region 7 Edwards Plateau
• Region 10 High Plans
• Region 11 Trans Peco

Plants prevent soil erosion by-

• holding dirt in place with their roots
• providing food for herbivores
• the process of photosynthesis
• releasing water into the atmosphere through transpiration

Why would there be less erosion in this ecoregion of Texas?

• not enough rain so the soil isn't washed away

• Tree and plant roots holds onto the soil

• tree and plant roots absorb the rain

• This ecoregion is one of the wettest
