General Knowledge
These shallow, fast-flowing areas of a stream help increase dissolved oxygen.
What are riffles?
This stage of the water cycle occurs when water vapor cools and turns into liquid droplets to form clouds.
What is condensation?
The land area that drains into a common body of water, such as a river, lake, or ocean.
What is a watershed?
This large Ohio salamander, known for its wrinkled skin, breathes primarily through its skin rather than lungs.
What is the Eastern Hellbender?
These aquatic organisms, such as mayflies and stoneflies, are used to assess water quality due to their sensitivity to pollution.
What are bioindicators?
Large rocks in a stream, typically over 10 inches in diameter, that create eddies and provide shelter.
What are boulders and slabs?
The process by which water seeps into the ground and replenishes underground reservoirs.
What is infiltration?
A slow-moving, deeper section of a stream located between riffles and runs, providing refuge for aquatic life.
What is a pool?
(200 pts) This species retains its external gills throughout its life, giving it a permanent larval appearance.
What is the Common Mudpuppy?
This measure of water clarity is affected by suspended particles such as silt, algae, and organic matter.
What is turbidity?
This winding feature of a stream develops naturally over time and plays a role in slowing water velocity and reducing erosion.
What are meanders?
This phase of the water cycle involves water being absorbed and released by plants back into the atmosphere.
What is transpiration?
These overhanging streambank features provide shelter for fish, reptiles, and amphibians, while also preventing bank erosion.
What are undercut banks?
(300 pts) This salamander has two rows of yellow spots running down its dark-colored back and only emerges in early spring to breed.
What is the Spotted Salamander?
A high level of this type of pollution can reduce oxygen levels in a stream, making it difficult for aquatic life to survive.
What is nutrient pollution (or excessive nitrogen and phosphorus)?
Often seen clumped along gravel bars, this aquatic plant stabilizes sediment, helps create islands, and provides essential cover for aquatic species.
What is Water-Willow?
The term for water moving across the surface of the land rather than being absorbed into the ground, often leading to erosion.
What is runoff?
This natural process within streams allows sediment to be transported, sorted, and deposited in different areas, shaping the streambed over time.
What is sediment transport?
Name the Ohio salamander that has a striking orange juvenile stage, known as the Red Eft, before returning to aquatic life as an adult.
What is the Red-spotted Newt?
A large population of these indicates clean water, free of pollution.
What is mayfly larvae?
This type of forest along a streambank provides shade, filters pollutants, and helps prevent erosion.
What is a streamside forest?
Name the three main ways water returns to the atmosphere as vapor, excluding human activities.
What are evaporation, transpiration, and sublimation?
hen excess sediment from upstream sources accumulates in a stream, it can degrade water quality and suffocate aquatic life. What is this harmful process called?
What is sedimentation?
This animals scientific name is Necturus maculosus
What is the common mudpuppy?
A large population of these, with a lack of biodiversity indicates highly polluted water.
What are bloodworms?
