Slow and Rapid Changes

The Rio Grande Valley is located at the southern tip of Texas at the end of a long river known as the Rio Grande. How did the delta at the end of the Rio Grande form? (5.7B)

• Sand and mud from the Gulf of Mexico were washed ashore by tsunamis.

• The river cut through the solid bedrock of the valley.

• The river deposited large amounts of sediment from land erosion.

• Hurricanes pushed soil and debris from the Gulf of Mexico onto the land.

A scientist was studying a type of event that occurred on Earth in various places within a 30-day period. The circles indicate where the events happened. The events being studied involved rapid changes to Earth's surface at the locations shown on the map. What type of event do the circles on the map most likely represent? (3.7B)

• Landslides, because they are all located along ocean coastlines

• Volcanoes, because they occur only near the equator

• Earthquakes, because they occur on land and on the ocean floor

• Floods, because heavy rains can make riverbeds deeper and create deltas
