7.8B Weathering, Erosion, Deposition POST

From the distinct shapes of sand dunes and their features in a desert, a geologist could most likely determine which of the following?

• The direction of the prevailing wind

• Daily high and low temperatures

• Amount of water nearby

• Age of the formations

The map shows the various ecoregions of Texas. Which ecoregion is most vulnerable to wind erosion from hurricanes originating in the Gulf of Mexico?

• Post Oak Savannah

• Blackland Prairies

• Edwards Plateau

• Gulf Prairies and Marshes

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.

The tall rock formations with smooth surfaces in Big Bend National Park were formed over time by -

• rock deposition.

• water erosion.

• wind weathering.

• local vegetation.
