WED in Ecoregions of Texas

Which of the following best explains the lack of extremely diverse landforms in this ecoregion?

• The high vegetation decreases erosion from water and wind.

• The trees in this region hide the diverse landforms underneath them.

• The trees broke down all of the previous landforms through weathering.

• The high amount of vegetation soaks up most of the corrosive water into their leaves.

Which of the following best explains how these islands formed in the Gulf Coast Prairies and Marshes Region?

• They formed as sand from the shore was deposited in a location where water movement slowed down.

• They formed as underwater volcanoes erupted and deposited lava

• They formed as a reef built up deposits so high that it created an above-water mass.

• They formed as hurricanes deposited sand from distant regions.

The formation of the Palo Duro Canyon in the High Plains Region was mostly due to —

• the erosion of land over millions of years by the swift-moving water of a river.

• tectonic plates causing the uplift of land.

• wind storms blowing away large chunks of land over millions of years.

• the chemical weathering of land from acidic rainfall.

The sand dunes in the in the Gulf Coast Prairies and Marshes ecoregion most likely formed by —

• the deposition of sand carried by swift wind blowing along the coast.

• land that slightly uplifted when tectonic plates moved under the beach sand.

• a primitive river that flowed toward the ocean and carved out the sand dunes.

• strong waves dumping chunks of the ocean floor onto the beach.

This ecoregion is characterized by having a dry climate, poor soil, large numbers of grazing animals, grasses, and oak trees. Which of the following plays the largest factor in the formation of this ecoregion?

• Wildfires and the constant wildlife grazing that erodes the soil

• Winds from hurricanes blowing down trees and weathering the land

• Chemical weathering of limestone and granite

• Flash floods that prevent diverse plant growth

The picture shows the Inner Space Cavern in Georgetown, Texas, that formed under the Edwards plateau. The formation of this cavern was most likely due to —

• the erosion of limestone, as carbon dioxide in the air and soil mixed with rainwater to form carbonic acid.

• the erosion of soil, as ocean waves hit land so far inland that they carried soil and created openings and caves underground.

• weathering of rock, as plant roots traveled deep into the soil and created spaces that grew larger as water washed soil away.

• weathering by wind, as tornadoes in this area scooped up large chunks of land and formed caves that filled with water.
