Unit 8 Catastrophic Events/Tex Eco/Weathering

How does a water well affect ground water?

• Water will continue to fill the well

• Water and human waste will be washed out

• Water in the aquifer will decrease

• Water that is stored will evaporate at an accelerated rate

As a river enters a larger body of water, sediments are deposited over a wide area. Which of these landforms is likely to be formed at the site of deposition?

• Cave

• Mountain

• Delta

• Valley

The geotropism of plant roots cause rocks to break apart; this is an example of-

• Erosion

• Chemical Weathering

• Deposition

• Physical Weather

Soil conservation is extremely important to farmers and ranchers in Texas. Crop rotation is one method farmers use. What is the main reason for using this method?

• Slows down soil removal by wind erosion

• Slows down soil removal by water erosion

• Slows down soil compaction

• Slows down nutrient depletion

The Piney Woods ecoregion of Texas annually has an average of 50 or more inches of rain each year. If there is a significant drought over several years, which of the following is a likely outcome of the drought?

• Tree and plant life will remain constant causing no change in erosion or weathering

• Tree and plant life will decrease leaving the soil exposed to increased soil erosion

Because much of the land has been overgrazed and has a flat topography, wind is a major agent of erosion in which Texas EcoRegion?

• South Texas Plains

• Gulf Plains and Marshes

• Piney Woods

• Post Oak Savannah

In the Texas Panhandle, Palo Duro Canyon was formed by the Red River. What will happen to the canyon in the future?

• Due to the deposition of sediments, it will start to narrow

• Due to water and wind erosion, it will continue to widen over time

• Due to agents of erosion, it will not have any change over time

• Due to the deposition of sediments, it will fill in and form a plain over time

What is the primary agent of erosion that forms a sand dune in the Coastal Region of Texas?

• Evaporation

• Fire

• Water

• Wind

Most of the damage done by hurricanes is caused by...

• storm surges that flood coastal areas

• lightning from thunderstorms

• trees falling due to high winds

• windows blowing out of buildings

Hurricane Harvey caused a widespread devastation in the Houston area in 2017. The slow movement of Harvey contributed to the destruction of homes and businesses. What catastrophic event occurred as a result of the Category 4 hurricane?

• Earthquake

• Tornado

• Tsunami

• Flooding
