What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, characterized by sediment deposition that creates a triangular or fan-shaped area.

Which rock type is most easily eroded by rivers?

Back

Sandstone is the rock type that is most easily eroded by river action due to its composition and structure.

Front

Why are caves found in Virginia's Valley and Ridge province?

Back

Caves are found in this area because it is underlain by limestone, which is susceptible to erosion by water.

Front

What is the streak test in mineral identification?

Back

The streak test involves observing the color of the powdered form of a mineral when it is scraped across a porcelain plate.

Front

What is continental drift?

Back

Continental drift is the theory that continents have moved over geological time and were once joined together in a single landmass.

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various geological processes, including melting, cooling, erosion, and compaction.
