To determine the natural cause that broke the sediment off the side of a valley, we need to consider several factors and processes that shape the Earth's landscapes. Here's a step-by-step guide on how to identify the natural cause:

1. Study the geological context: Start by examining the geological characteristics of the valley. Consider the type of rocks and soils present, as well as the overall geological history of the area. This information can provide clues about the forces that may have caused the sediment to break off.

2. Analyze the valley's formation: Understanding how the valley was formed can shed light on the possible causes of sediment collapse. For instance, valleys can be created through erosion by rivers, glaciers, or tectonic activity like faulting or folding. Each of these processes may have different mechanisms for sediment detachment.

3. Assess weathering and erosion: Examine the weathering patterns in the valley. Weathering refers to the breakdown of rocks and sediments over time due to natural elements, such as water, wind, ice, or temperature changes. Erosion, on the other hand, involves the removal and transportation of the weathered materials. Evaluating the intensity and type of weathering and erosion can provide insights into the potential causes of sediment detachment.

4. Consider external factors: Take into account the external factors that might play a role in the sediment detachment. For example, seismic activity such as earthquakes or landslides can cause significant disturbances in the landscape. Additionally, natural processes like freeze-thaw cycles, gravity, or vegetation growth might contribute to sediment detachment.

5. Analyze evidence: Look for physical evidence, such as fractured rocks, tilted layers, or debris deposits, which can provide additional clues about the cause of sediment detachment. Consulting geological maps, aerial photographs, or satellite imagery might help in identifying any significant landscape changes.

By examining these factors and processes, combined with a detailed analysis of the geological context, you can identify the natural cause that broke the sediment off the side of the valley.
