How does current affect biodiversity in rivers and streams? It prevents bacteria and algae from living in rivers and streams. It causes a decrease in biodiversity by preventing organisms from remaining in rivers and streams. It mixes the nutrients for plant and animal use and determines location of organisms.
Do streams have a detectable current while rivers?
Streams have a detectable current, while rivers do not. Currents shape rivers over long periods of time.
Which statement is characteristic of streams and rivers?
Key Characteristics of Rivers and Streams. Streams or rivers form when water that does not find an underground aquifer, drains off the land by either seeping through the soil or spilling over the surface into the river or stream bed. Water in streams and rivers is in constant motion.
Which of the following is a way that humans impact rivers and streams quizlet?
Which of the following is a way that humans impact rivers and streams? Dams have a limited effect on rivers and streams.
Where does the water in streams and rivers originate a precipitation?
Most of the water you see flowing in rivers comes from precipitation runoff from the land surface alongside the river. Of course, not all runoff ends up in rivers.
Where does the water in rivers come from what causes rivers to flow quizlet?
In the case of rivers, the water comes from precipitation that falls over mountains or hills. It flows downhill and forms tiny streams called tributaries.
How the conversion of wetlands to farmland has impacted streams and rivers?
Explain how the conversion of wetlands to farmland has impacted streams and rivers. Wetland reduction has caused a decrease in the absorption zones for excess water. If the excess water cannot be absorbed by the soil, it increases the incidence and magnitude of flooding.
How do rivers and streams transport matter?
Streams move downslope under the influence of gravity, the passage of water is called stream flow. … Sediments are moved by streams in different ways. Fine grained particles and dissolved components are carried in suspension (called the suspended load). With increasing turbulence, the suspended load increases.
What is the importance of keeping water flowing in streams and rivers?
Streams, headwaters and streams that flow only part of the year provide many upstream and downstream benefits. They protect against floods, filter pollutants, recycle potentially-harmful nutrients, and provide food and habitat for many types of fish.
How surface rivers and streams produce erosion?
Rivers and streams erode the land as they move from higher elevations to the sea. Eroded materials can be carried in a river as dissolved load, suspended load, or bed load. A river will deeply erode the land when it is far from its base level, the elevation where it enters standing water like the ocean.
Is a way that humans impact rivers and streams?
Pollution enters the river, sometimes in small amounts, at many different locations along the length of the river. … Sewage and effluent are discharged into rivers in some areas. Pollution can lower the pH of the water, affecting all organisms from algae to vertebrates. Biodiversity decreases with decreasing pH.
How can an increase in biodiversity lead to an increase in ecosystem stability?
How can an increase in biodiversity lead to an increase in ecosystem stability? … An increase in the biodiversity of an ecosystem leads to an increase in its productivity. T. Ecosystems with greater biodiversity have an increased stability.
What contributes to the high level of biodiversity found in wetlands?
Terms in this set (14) The abundance and variety of foods available in wetlands is a large contributor to their biodiversity. … Wetlands help slow the process of erosion by trapping sediments.
