Where should you aim your boat to find the deepest water?
Look for the area of the bar or inlet that has the smallest waves. This is usually the area with the deepest water. When returning in a big following sea, keep the boat straight and on the backside of a wave, experts suggest.
Where along a meandering stream would erosion occur most intensely?
Due to the slope of the channel, erosion is more effective on the downstream side of a meander. Therefore, in addition to growing laterally, the bends also gradually migrate down the valley.
What is the best paddling route to maximize your speed upstream?
Assuming you don’t want to go backwards, what is the best paddling route to maximize your speed upstream? Stay on the inside bend of meanders, crossing over whenever the meander turns so you can stay on the inside bend.
What term refers to the volume of water moving past a given point in a certain amount of time?
We know that the oceans contain most of Earth’s water. The amount of water flowing past a certain point in a given unit of time is termed the infiltration capacity.
What do you call the movement of the surface of the water?
it is called hydrologic cycle, or water cycle, Surface movement includes. rivers, streams, creeks, lakes, ponds, and human-made “flood” control.
What is the load of a stream?
Stream load is a geologic term referring to the solid matter carried by a stream (Strahler and Strahler, 2006). Erosion and bed shear stress continually remove mineral material from the bed and banks of the stream channel, adding this material to the regular flow of water.
What type of load is sand?
Suspended load generally consists of fine sand, silt and clay size particles although larger particles (coarser sands) may be carried in the lower water column in more intense flows.
What happens when a stream slows down?
When a stream or river slows down, it starts dropping its sediments. Larger sediments are dropped in steep areas. Some smaller sediments can still be carried by a slow moving stream or river. Smaller sediments are dropped as the slope becomes less steep.
What is the difference between bed load and suspended load?
Bed load consists of sediments that are moving along in a river bottom, or just above the bottom, essentially by either rolling or “saltation,” where particles bounce along the bottom. Suspended load consists of generally finer, smaller particles than bed load (like silt and clay).
Under what conditions is it safe to stand on a suspended load?
The fall zone as defined by OSHA is “the area including, but not limited to, the area directly beneath the load in which it is reasonably foreseeable that partially or completely suspended materials could fall in the event of an accident.” OSHA goes on to state that standing under a suspended load is prohibited and …
What is bed load transport?
Bedload transport is a specific form of sediment transport, which involves coarse particles (sand, gravel or coarser particles) rolling or saltating along the streambed.
What terms are associated with a stream’s bed load?
Streams carry dissolved ions as dissolved load, fine clay and silt particles as suspended load, and coarse sands and gravels as bed load.
Which is the most common type of drainage pattern?
dendritic drainage pattern
What are the three ways in which rivers and streams carry their bed load?
Streams transport their load of sediment in three ways: in solution (dissolved load), in suspension (suspended load), or scooting or rolling along the river bottom (bed load).
Which agent of erosion is most likely to move sand dunes?
Wind can move soil, sand, and small pieces of rock. Therefore, wind can cause erosion. However, some areas are more likely to have wind erosion than other areas. For example, plant roots help to hold soil and rock in place.
What are 5 erosion agents?
Five agents of erosion are gravity, running water, glaciers, waves, and wind.
What is the slowest agent of weathering and erosion?
Wind- the least powerful can only move small pieces of rock. It is the slowest agent of erosion.
What is the biggest agent of erosion?
Liquid water
What are the 3 main agents of erosion?
Water, wind, ice, and waves are the agents of erosion that wear away at the surface of the Earth.
What are 4 major agents of erosion?
Erosion is the transportation of sediment at the Earth’s surface. 4 agents move sediment: Water, Wind, Glaciers, and Mass Wasting (gravity).
What is the most powerful agent of erosion and why?
Moving water is the strongest agent of erosion that has shaped Earth’s land surface.
Which 2 agents are responsible for most soil erosion?
The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away.
What is the most powerful agent of weathering?
Water is the most important agent of chemical weathering. Two other important agents of chemical weathering are carbon dioxide and oxygen.
What is the most important factor in erosion?
The most important erosion factors include the climatic, hydrological, topographic, soil, geological and vegetation conditions, as well as the economic and technical and the socioeconomic conditions of the human society.
What are the nine factors that aid erosion?
Factors that Influence or Cause Soil Erosion
- RAINFALL: Consistent heavy rains usually causes erosion of soil at a faster rate.
- TOPOGRAPHY: It refers to the extent to which a land slopes.
- PRESENCE OF ORGANIC MATTER IN SOIL:
- HUMAN ACTIVITIES:
- OVERGRAZING:
- DEFORESTATION:
Where is erosion greatest in a river?
Most river erosion happens nearer to the mouth of a river. On a river bend, the longest least sharp side has slower moving water. Here deposits build up. On the narrowest sharpest side of the bend, there is faster moving water so this side tends to erode away mostly.
What are three factors that affect water erosion?
Objective. Climate, soil properties, vegetation, soil cover, and land management practices are factors that influence both water and wind erosion.
What affects the rate of erosion?
The more erodible the soil, the greater the rate of erosion and the shorter the distance to maximum soil movement. Major factors that affect the amount of erosion are soil cloddiness, surface roughness, wind speed, soil moisture, field size, and vegetative cover.
What factors can increase the amount of erosion by water?
Human factors include run-off from farm fields and parking lots and water releases from dams that increase the amount of water flowing in streams. Removal of trees and shrubs from stream banks and deadfall from within the stream makes them more susceptible to erosion and increases stream flow.
What are the factors affecting wind erosion?
