• Two of the four cubes are soluble in water.

• All four cubes have different masses.

• Each cube is made of a different type of solid material.

• One of the cubes is more dense than the other three.

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?

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

• 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.
