Skepticism
Which part of scientific design occurs when an experiment is conducted by more than one scientist to determine the validity of results replication research trials variables?
The answer is: Trials.
Which of the following is the most likely reason that the scientists will use a model instead of creating an actual oil spill to study?
The scientists decide that the best way to complete the study is to create a model. Which of the following is the most likely reason that the scientists will use a model instead of creating an actual oil spill study? a. They think using a model will provide them with more accurate results.
Why was DDT intentionally released into the environment?
Why was DDT intentionally released into the environment? It was applied in swamps to kill mosquitos that spread malaria.
What are natural oil seeps?
An oil seep is a natural leak of crude oil and gas that migrates up through the seafloor and ocean depths. Seeps occur when crude oil leaks from fractures in the seafloor or rises up through seafloor sediments, in much the same way that a freshwater spring brings water to the surface.
Which ocean is the source of oil hub?
The most productive areas are currently the North Sea and the Gulf of Mexico, the Atlantic Ocean off Brazil and West Africa, the Arabian Gulf and the seas off South East Asia. For some years now the trend has been towards drilling in deeper and deeper water.
Is there WIFI on oil rigs?
Leisure facilities differ, but modern rigs often have games rooms, gyms and cinemas. Before internet, workers could only call home once a week for 6 minutes! These days most rigs have wifi for Skype, social media and emails on tablets and laptops, although mobile phones are often banned and phone signal is rare.
Do Wells cause sinkholes?
Well drilling generally triggers sinkholes when the water table fluctuates either because the well is being pumped clean with water or because water is being drawn out, Scott said. Additionally, if a well is being drilled into an area with a cavity, that cavity may collapse.
What are the warning signs of sinkholes?
What are the warning signs?
- Fresh cracks in the foundations of houses and buildings.
- Cracks in interior walls.
- Cracks in the ground outside.
- Depressions in the ground.
- Trees or fence posts that tilt or fall.
- Doors or windows become difficult to open or close.
- Rapid appearance of a hole in the ground.
What is the difference between a sinkhole and a depression?
Sinkholes are just one of many forms of ground collapse, or subsidence. Land subsidence is a gradual settling or sudden sinking of the Earth’s surface owing to subsurface movement of earth materials. A sinkhole is a depression in the ground that has no natural external surface drainage.
Whats at the bottom of a sinkhole?
Occasionally a sinkhole may exhibit a visible opening into a cave below. Sinkholes are common where the rock below the land surface is limestone or other carbonate rock, salt beds, or in other soluble rocks, such as gypsum, that can be dissolved naturally by circulating ground water.
How deep can a sinkhole be?
What is a “sinkhole”? A sinkhole is an area of ground that has no natural external surface drainage–when it rains, the water stays inside the sinkhole and typically drains into the subsurface. Sinkholes can vary from a few feet to hundreds of acres and from less than 1 to more than 100 feet deep.
How much does it cost to repair a sinkhole?
“When you make a sinkhole claim with an insurer, it costs $10,000 just to diagnose the problem,” says Brashear. “You have to go 30 to 100 feet below the ground level just to determine the hole is there. Then it will usually cost between $50,000 and $200,000 to fix.”
