Where do ice wedging mostly occur?
Sidewalks and roads where the ice matter gets forced into cracks. It occurs most often in moderately cold climates because the ice needs to melt and then re-freeze
What occurs when a cold air mass displaces a warmer air mass?
This is a cold front. The warm air is forced upwards by the cold air wedging underneath, often forming a narrow line of heavy precipitation.
Where is frost wedging most likely to occur?
Frost wedging occurs in small cracks in the rock where water seeps in. The water then freezes and expands (fun fact: water is the only knowns natural substance that expands when freezing, and is also the only substance capable of existing in all three basic states of matter--liquid, solid, and gas--at naturally occurring temperatures), which then splits--or "wedges--the rock apart. I've attached an image for graphic demonstration.
What makes potholes in the road?
A pothole is a depression in a roadway that can range from a few inches wide and a few inches deep, to several feet wide and sometimes a foot deep. Potholes jar the tires of cars driving over them sometimes causing handling and suspension problems.Since potholes form in both gravel and paved roads it is not a simple matter of rain washing the material away, and since rain falls equally on all the road the wearing effect should be equal over the whole surface. Another consideration is that potholes seem to appear in the spring. Furthermore, potholes can form in cold climates as well as hot climates only for different reasons. Potholes seem to be the result of several factors depending on where you live.In colder climates:The freezing and thawing of the road surface lifts the road material up making cracks in the surface.These cracks formed to fill with water which freezes and expands the cracks wider.The thawing water washes the broken material out of the cracksCars traveling the road hit the small cracks vibrating even more material loose from the area.As the holes continue to grow the bumping gets more severe, breaking more of the surface loose.As these breaks get wider the asphalt is able to rock loose leaving the pothole behind.In warmer climates:Over time as the sun heats up the asphalt it will start to dry out the oil and binders which hold the asphalt in place.Once the asphalt reaches a critical point of dryness it becomes less able to absorb shock from the cars traveling on the road or parking lot.Eventually the asphalt will form fine cracks, typically found in the drive path areas of roads and parking lots.When winter rains come these cracks fill with water and begin to widen.Once the cracks are large enough the asphalt will pop out do to vibrations from vehicular traffic.In either climate the pothole process is initiated by small breaks in the surface. Some are caused by freeze/thaw cycles and others are caused by asphalt drying out due to long term sun exposure. The potholes continue to form from exposure to rain and traffic. After time the original material becomes loosened and eventually fails completely. Leaving behind the pothole.The next question is why do potholes appear in the same places year after year. This results from the repair of potholes with cold pack asphalt. If the material is not installed properly (bonded in palace with tar and tamped and rolled into place) it is easier to break up than the rest of the road surface, Sort of like the problems with a poorly filled dental cavity. As a result the new pothole forms where the surface is weakest, the site of the poor repair.On gravel roads potholes often result from another cause, the natural frequency of the tire and shock absorber system of car. These potholes can be either individual depressions or ridges that run normal to the flow of traffic. This latter condition is more commonly known as a washboard road. In this case some minor irregularity of the road causes a car tire to bump up. When it comes down it impacts the clay and gravel compacting it slightly. This forms a depression which causes another compression and release of the suspension. The period of the movement is due to the natural frequency of the system. Eventually this causes a series of depressions each time the tires rise and fall.On the lighter side:It is caused by marijuana smokers throwing their roaches out the windows. That causes pot holes.
Is it true that air pollution from industry often causes rainwater to become acidic?
It is fairly common in some countries that air pollution causes acid rain.
What often causes potholes in streets?
ice wedging
Where does frost wedging occur most often?
In temperate climates
What special factors affect driving on residential streets?
Cities and suburbs can be hectic,crowded places. Cars, buses, trucks, and other vehicles crowd the streets. For much of the day, pedestrians may fill the sidewalks. People can cross the street at any time. Double-parked vehicles often block visibility, and potholes may interrupt traffic flow.
What often causes pothpoles in streets?
Potholes are holes created in the road due to various stresses. On tar roads, the tar can expand and contract considerably during the summer and the winter. As a result of this constant contraction and expansion, parts of the road can erode away. During the winter, ice can also form in the pores in the tar road and the freezing of the ice expands the road slightly. Over days, weeks, and months of exposure to such stresses, tar roads break away at weak points and form potholes. Continued driving and application of the weight of multiple cars and trucks can also facilitate the road's destruction. The same can occur on concrete roads, although not as often as on tar roads.
Oxbow lakes are formed in potholes?
Oxbow lake are usually formed in flat, low-lying plains close to where the river empties into another body of water. They are usually stillwater lakes and often they become swamps or bogs, not potholes.
What factors affect urban and suburban driving?
Cities and suburbs can be hectic,crowded places. Cars, buses, trucks, and other vehicles crowd the streets. For much of the day, pedestrians may fill the sidewalks. People can cross the street at any time. Double-parked vehicles often block visibility, and potholes may interrupt traffic flow.
What is the name of the material placed in the gaps between the concrete sections?
Cementanswer #2The material is an asphalt impregnated fiber material designed to block and penetration of water and be somewhat flexible. During the lifetime of the roadway the maintenance efforts will often fill the gaps with a liquid tar based sealant to keep water out and prevent the creation of potholes. Water gets through and washes out the supporting structures which causes cracking. Water and ice are the enemies that cause potholes and other problems.
What causes often erections?
often excitement.
Which city has the most potholes in the US?
There isn't a definitive answer to this question as it can vary depending on the year, location, and reporting methods. However, cities like Detroit, Los Angeles, and New York City are often cited for having a high number of potholes due to climate, traffic volume, and aging infrastructure.
Why is it better to drive on the main street instead of side streets?
Main streets are often wider, have better visibility, and are designed to handle higher traffic volumes compared to side streets. Main streets typically have traffic lights for better traffic flow and are more well-maintained for smoother driving experiences. Additionally, main streets tend to have fewer obstacles and potential hazards than side streets.
What makes pot holes?
Potholes are typically formed due to a combination of factors such as water seeping into cracks in the road, freezing and expanding during cold weather, along with the constant wear and tear from vehicle traffic. Over time, this weakens the pavement, leading to the formation of potholes.
Where did krumping come from?
Kumping originated from the streets of america, t was often used as a subsitute to violence.
