What is the leading source of pollution in U.S. water bodies?
Answers
Answer: Agricultural Run-off
Explanation:
Agriculture is the leading source of impairments in the Nation's rivers and lakes. About a half million tons of pesticides, 12 million tons of nitrogen, and 4 million tons of phosphorus fertilizer are applied annually to crops in the continental United States.
Final answer:
In the U.S., water pollution primarily stems from human activities including agriculture, industry, and urbanization. Key pollutants are nitrogen and phosphorus from agricultural fertilizers and various contaminants from industrial and urban waste. These impact the health of aquatic systems and can also affect humans and land animals through the food chain.
Explanation:
The leading source of pollution in U.S. water bodies is primarily due to human activities such as industrialization, agriculture, and urbanization. One key contributor is the use of artificial fertilizers in agriculture that contain nitrogen and phosphorus compounds. These compounds often end up in lakes, rivers, and streams via surface runoff, leading to a process known as eutrophication. This is characterized by the uncontrolled growth of aquatic algae, which can make the water anaerobic and inhospitable for other aquatic organisms, evident in the formation of 'dead zones' in certain water bodies.
Additionally, industrial and urban waste, including untreated or partially treated sewage, contributes significantly to water pollution. Chemicals, radioactivity, and heat levels from these sources can further degrade the quality of water and disrupt aquatic life. It's important to note that as these pollutants move along the food chain, they can also affect land animals and humans who consume these aquatic resources.
Efforts towards cleaner water are necessary to mitigate these effects, akin to actions taken after severe pollution incidents such as the multiple fires on the Cuyahoga River in Cleveland in the past.

Ocean currents affect the temperatures of some regions. Some ocean currents carry warm water into the north. The British Isles in western Europe, for example, has a warmer climate than other areas at the same latitude, such as Labrador, Canada. A current called the Gulf Stream brings warm water to the British Isles. The Gulf Stream helps keep the climate warmer than it would be otherwise. After reaching far north, the current cools and flows south. Other currents carry cold water away from polar regions and make the climate of areas they travel to colder than they would be. Currents can warm or cool the air over them. The wind can carry that air into neighboring land areas.

Answer:
Noontime shadows are longer in the Northern Hemisphere than in the South
Explanation:
- The angle that the sun's rays make with the earth depends on the latitude and altitude. As the amount of solar radiation reaching the earth is 90 degrees over the as smaller the angle the more is the intensity of heat.
- This fluctuation is seen in temperature and seasonal patterns The Sun in the Northern hemisphere sky is made a more steep angle with the ground a but the sunlight is equal for the north and southern hemisphere.
- The time of the day is thus an important factor in latitudinal heat distribution.

Explanation:
Use the slope formula:
m = (y2 -y1)/(x2 -x1) = (5 -(-2))/(3 -5) = 7/-2 = -3.5
The slope is -3 1/2.

Explanation:
Answer:
The Medellin Cartel was extremely wealthy and controlled almost all of the cocaine being imported into the US. They used their wealth and influence to bribe members of law enforcement and the government to escape justice. They also murdered witnesses, police officers, other members of law enforcement, and judges, and assassinated the head of the justice department. They even conducted a terrorist attack against the Colombian Supreme Court, killing many justices. The Colombian government realized that it would be very difficult to convict the traffickers in Colombian courts, so they agreed to hand over suspects to the US for questioning in trial, as the cartel had no such power in America.
