Answer 1

Investigating the cleanliness of a local river or stream involves observing the water flow and collecting samples to analyze. The water can appear dirty due to sediment, pollutants, or organic matter. The source of the dirty water can be influenced by human activities or natural processes.

Step-by-step explanation:

When investigating a local river or stream, it is important to choose a part where the water is flowing fairly quickly. The cleanliness of the water can be observed by collecting some in a clear plastic jar and shaking it. If the water appears dirty, it could be due to sediment, pollutants, or organic matter such as leaves and debris.

The source of the dirty water can vary. It could be from runoff from nearby roads, agricultural activities, industrial discharge, or even natural processes like erosion. The water quality can be affected by both human activities and natural factors.
