How can groundwater erosion result in the formation of a sinkhole?
When too much erosion occurs in a cave the of the cave will collapse and create a sinkhole.
Chemicals and pesticides get into groundwater supplies through?
Sometimes referred to as groundwater contamination, groundwater pollution is not as easily classified as surface water pollution, as contamination may not be easy to recognise. Groundwater, by it's very nature, is more susceptable to contamination from sources that may not directly affect surface water bodies. Groundwater can become contaminated by those drilling for oil or gas wells. Groundwater may be polluted through a spill or ongoing realease of chemical or radionuclide contaminents into soil, polluting the aquifer below yet not the surface water body above. This is defined as a toxin plume, and as it travels it is defined as a plume front. Analysis of groundwater pollution usually focuses on the soil characteristics, geology, hydrogeology, hydrolgy and the nature of the contaminants at the site.
Is flood plain not an example of a wetland?
No, not necessarily. A flood plain is a situation which occurs when a body of water floods its banks. It is a temporary situation. A wetland is a situation that occurs when water from springs, streams, and so forth stays in place for years, allowing certain water-loving plants and animals to grow and thrive.
How are the process of weathering erosion and doposition related?
Weathering occurs when rocks are broken down into smaller particles but not moved When natural forces begin to move weathered particles, called sediments, we say that they are being eroded, or undergoing erosion. Most of earth's erosion is done by flowing water in streams which carry tons of sediment to the oceans each day Deposition occurs when movement slows or stops and suspended sediments are dropped.
What is the scientific definition of weathering?
Any of the chemical or mechanical processes by which rocks exposed to the weather undergo chemical decomposition and physical disintegration. Although weathering usually occurs at the Earth's surface, it can also occur at significant depths, for example through the percolation of groundwater through fractures in bedrock. It usually results in changes in the color, texture, composition, or hardness of the affected rocks.
Where a streams curves deposition occurs?

What step occurs next after extraction in the mineral resource cycle?
Refining!
Groundwater is the most effective erosion agent in what areas?
Groundwater erosion occurs most often in areas with an abundance of limestone and rainfall. This erosion can create large cavities and caves.
What occurs when two streams flow perpendicular to each other?
Ground that stands still
What is manifest conflict?
passive aggressive conflict occurs in what stage?
How can groundwater erosion result in the formation of a sinkhole?
When too much erosion occurs in a cave the of the cave will collapse and create a sinkhole.
Can you get a dry socket 4 days after a tooth extraction?
Yes. It usually happens at least 24 hours after an extraction. But this is also the time period when an extraction hurts the most - see your dentist who can tell you whether it's actually dry socket or just post-op pain.
What are the reactions that occurs in the blast furnace during extraction of iron?
C + O2 --> CO 3CO + Fe2O3 --> 2Fe + 3CO2
What drainage pattern occurs when streams diverge from a central high area like spokes from the hub of a wheel?
radial
What are the role of bacteria in the purification of streams and rivers?
There is a field of study call self-purification, that occurs in streams, rivers and ponds. The biological factors that enhance self-purification are the friendly bacteria that are part of the natural eco-system.
What is the natural habitat of Eastern Indigo Snake?
The Western Indigo Snake occurs in grasslands or bushy areas near rivers and streams.
