Question

The Trans-Pecos ecoregion in the western portion of Texas

receive less than 38 cm of rainfall a year and has little soil due
to overgrazing by farm animals. What catastrophic event is
most likely the cause the most weathering and erosion in the
least amount of time in this ecoregion?


1.Wildfire
2.Earthquake
3.Flood
4.Tornado

Answer 1

3.Flood

Step-by-step explanation:

Flood is the catastrophic event which is the main cause of the most weathering and erosion in the least amount of time in this ecoregion because there is no vegetation present in this region and the soil is vulnerable for erosion. Flash-flooding and rapid runoff are agents of erosion in the Trans-Pecos ecoregion of Texas whenever the rainfall occurs. Vegetative is very important for preventing soil erosion so the people of this region has to stop overgrazing in this area in order to avoid more erosion of the soil.
