What is an Oxbow Lake?

Back

An Oxbow Lake is a crescent-shaped lake formed when a river meanders and erodes its banks, eventually cutting off a bend to create a separate body of water.

Front

How does erosion contribute to the formation of an Oxbow Lake?

Back

Erosion occurs as the river curves, wearing away the outer bank and depositing sediment on the inner bank, leading to the eventual cutoff of the bend.

Front

What are tectonic plate boundaries?

Back

Tectonic plate boundaries are the edges where two tectonic plates meet, often associated with geological activity such as earthquakes and volcanic eruptions.

Front

What is Delta Formation?

Back

Delta Formation is the process by which sediment carried by a river is deposited as the river flows into a larger body of water, creating a landform.

Front

What is sedimentation?

Back

Sedimentation is the process of settling or being deposited as sediment, often occurring in bodies of water where particles accumulate.

Front

Where does the greatest amount of deposition occur in a stream?

Back

The greatest amount of deposition occurs at the mouth of the stream, where it enters a larger body of water, typically at Location 4.

Front

What is Freeze Thaw Erosion?

Back

Freeze Thaw Erosion is a geological process where water seeps into cracks in rocks, freezes, expands, and eventually breaks the rock apart.

Front

What role do rivers play in shaping the Earth's surface?

Back

Rivers shape the Earth's surface through erosion, transportation of sediments, and deposition, creating various landforms like valleys and deltas.

Front

What is the significance of volcanic activity in relation to tectonic plates?

Back

Volcanic activity often occurs at tectonic plate boundaries, where plates diverge or converge, leading to the formation of volcanoes.

Front

What is the difference between erosion and weathering?

Back

Erosion is the process of moving sediment from one location to another, while weathering is the breakdown of rocks into smaller pieces without movement.
