Electrons are basically surrounding the nucleus (containing the protons and the neutrons), and are "swirling" around the nucleus, forming a cloud like shape around the nucleus.
Levels Levels
The accumulation of pollutants at successive levels of the food chain is known as biomagnification. This process occurs when toxic substances, such as heavy metals or pesticides, are taken up by organisms and become increasingly concentrated as they move up the food chain. Predators at higher trophic levels ingest multiple prey, leading to higher concentrations of these pollutants in their bodies. As a result, top predators can experience significant health risks and ecological impacts due to this accumulation.
There are no levels of scared. Only that you can get very freightened.NO! THere is shocked and others
The twice-daily event that causes water levels around Jamestown to rise and makes wells and fresh water streams become brackish is the tide. The tidal cycle brings in seawater, increasing the salinity of the water in wells and freshwater streams located in the vicinity of Jamestown.

The twice-daily event causing water levels to rise and affecting freshwater sources around Jamestown is the tidal cycle. During high tide, saltwater from the nearby ocean is pushed inland, raising water levels and mixing with freshwater sources like wells and streams, making them brackish.
I think something to do with saltwater.

Brackish water in Jamestown was primarily caused by the combination of rising sea levels and excessive groundwater extraction. The colony's reliance on wells for fresh water, coupled with drought conditions, led to saltwater intrusion from the nearby Chesapeake Bay. This intrusion resulted in a mix of saltwater and freshwater, creating brackish conditions that compromised the availability of potable water for the settlers. Additionally, poor site selection for the settlement, located on a peninsula, further exacerbated the issue.
Portuguese food is usually brackish.The doctor told him to avoid brackish food.
Brackish soils are soils that contain a mixture of saltwater and freshwater, with higher salinity levels than freshwater but lower salinity levels than seawater. These soils can be found in coastal areas, estuaries, and marshlands, and are typically a result of tidal influence and the mixing of saltwater and freshwater. Brackish soils can have specific challenges for plant growth and agriculture due to the unique salinity levels.
Brackish fauna refers to the diverse range of animal species that inhabit brackish water environments, which are characterized by a mix of freshwater and saltwater, typically found in areas such as estuaries, mangroves, and coastal lagoons. These organisms have adapted to the fluctuating salinity levels of brackish waters, allowing them to thrive in these unique ecosystems. Common examples include certain species of fish, crustaceans, and mollusks that can tolerate varying salinity. The health of brackish fauna is often indicative of the overall health of their aquatic habitats.
Brackish water is a mix of fresh and saltwater, typically found in estuaries or coastal areas. It has a salinity level higher than freshwater but lower than seawater. This type of water supports a unique ecosystem adapted to fluctuating salinity levels.
- after irrigation salt from the water remain in the soils- in some regions rivers carry salted waters from the mountains- a local contamination from an industrial activity- contamination from sea water or other bodies of salt water
Wells and freshwater streams become brackish primarily due to the intrusion of saltwater, often as a result of rising sea levels or excessive groundwater extraction. When the natural balance between freshwater and saltwater is disrupted, saline water can seep into aquifers or freshwater bodies. Additionally, coastal flooding and storm surges can also introduce saltwater into freshwater systems. This change in salinity can adversely affect aquatic ecosystems and water quality for human use.
