how are coastal waters and deeper ocean waters polluted? provide examples for each. the more you provide, the more you are likely to recall some of them.
Coastal waters and deeper ocean waters are polluted in a variety of ways, both from natural and human-made sources.
Some examples of pollution in coastal waters include:
Sewage and wastewater discharge: Many coastal cities and towns discharge untreated or partially treated sewage into the ocean, which can contain bacteria and pathogens that can harm marine life and make the water unsafe for swimming or other recreational activities.
Agricultural runoff: In coastal areas where agriculture is prevalent, runoff from farms and fields can carry fertilizers, pesticides, and other chemicals into the ocean, which can harm marine life and disrupt delicate ecosystems.
Oil spills: Coastal waters are particularly vulnerable to oil spills, which can happen due to accidents involving ships or oil drilling operations. Oil can smother and suffocate marine life, and can be difficult to clean up, especially in remote areas.
Plastic pollution: Plastic debris, such as plastic bottles, bags, and microplastics, are a major problem in coastal waters. These materials can harm marine life and damage ecosystems, and can take hundreds of years to degrade.

Match the processes of the water cycle with its correct description.
Evaporation Condensation [Choose ] Water in clouds becomes too heavy and must fall to Earth Water flowing along the top of Earth Loss of water by plants to the atmosphere Water moving through soil and rock layers to groundwater below Water in the atmosphere forms droplets that create clouds Water moves from oceans and other water bodies into the atmosphere [Choose Precipitation Transpiration [Choose) LL Surface runoff [Choose ] + la te Infiltration [Choose]
The process of the water cycle, with an accurate description, is "evaporation" which means "water moves from oceans and other water bodies into the atmosphere".
Evaporation is the process of water changing from a liquid state to a gaseous state. It occurs when the sun's energy heats the water in oceans, lakes, rivers, and other bodies of water, causing the water molecules to escape into the air as water vapor. This process is an important part of the water cycle, as the water vapor then rises into the atmosphere and can be cooled to form clouds, which can then precipitate back to the surface as rain or snow. Evaporation is a natural process that keeps the amount of water on Earth in balance.

compared to historical trends, what is different about contemporary climate change?
Answer:
Today's global warming is happening at a much faster rate today than it did in the warm periods between ice ages over the last million years. The transition from the last ice age to the current interglacial period is estimated to have spanned 5,000 years. Humans could witness the same magnitude of global warming within a span of about 110 years. In other words, if our world warms by as much as 7°F (4.1°C) from 1990 to 2100, as some climate models project could happen, then that warming rate is about 45 times faster than the warming Earth experienced when it emerged from the last ice age.

Explanation:
Type in the box below.
Describe a real-life occurrence in which human activity has caused a major flood. Make sure to describe in detail the cause and the impact of this flood. You may need to conduct some research to enrich your knowledge. Complete at least two well developed paragraphs, 5-7 sentences long. Check your grammar and spelling to avoid point deductions.
The Johnstown Flood of 1889. The storm sprang from the combined actions of the South Fork Fishing and Hunting Club, who had significantly altered the landscape of the area around the South Fork Dam. The South Fork Dam was built in the mid 1800s to create a lake as a recreational area for the wealthy members of the club. However, the dam had been poorly maintained since its construction, and was not up to modern safety standards.
The storm that caused the flood began on May 31, 1889 and continued through June 1 of the same year. This storm, comprised of several days of heavy rain, caused the Little Conemaugh and Stony Creek River to swell beyond the capacity of the ill-kept South Fork Dam. At approximately 3:10pm on June 1, 1889, the dam breached and released a wall of water over 14ft high which surged downstream towards Johnstown.
The flood, in combination with the debris it swept along, caused devastating damage to the city of Johnstown, of which 2,209 people were killed and many left homeless. In the aftermath of the disaster, assessments of the cause determined that the South Fork Dam, poorly maintained for the past 30 years, was to blame for the flood’s severity.
The Johnstown Flood serves as a potent reminder of the importance of proper maintenance and upkeep of man-made structures, particularly those related to flood control and management. Had the South Fork Dam been maintained to modern safety standards, the severity of the flood and its destructive impact on the city of Johnstown would have likely been reduced.

Channels with gradual slopes often develop a sinuous form called a ______ pattern. A) straight B) braided stream C) anabranching D) meandering stream.
Meandering streams are created when a channel with gradual slopes forms a sinuous pattern.
The Benefits of Meandering Streams
The sinuous form of a river channel with a gradual slope is called a meandering stream. This type of river pattern develops over time as the flow of water erodes and transports sediment, creating curves and bends in the channel. The curves of a meandering stream are often wide, looping back and forth across the landscape in a sinuous pattern.
The erosional forces of a meandering stream are highly effective in shaping the landscape. As the stream curves and shifts, it erodes banks and deposits sediment in new areas, creating wetlands, oxbow lakes, and other features along its course. This process can create lush floodplains, which are often rich in biodiversity and provide valuable habitat for wildlife. In addition, meandering streams can help to protect against flooding by dissipating the energy of a flood, reducing its severity.
