Answer:
The statement is not true.
Explanation:
Global warming is a process that is occurring naturally, with or without human activity. This is not to say that humans don't have an impact, on contrary, the human activities have managed to add enough greenhouse gases in the atmosphere so that the process is speeded up, and that becomes very alarming because the changes are much faster.
Very often, the finger is pointed to the most developed countries in the world when it comes to greenhouse gas emissions like they are the only ones that contribute to it. This is far from true though. All of the well-developed countries, except for the US, have been investing heavily in environmentally friendly energy sources and have had a decrease in greenhouse emissions. On the other hand, countries like China, India, Indonesia, Pakistan, Nigeria, are all among the top polluters when it comes to greenhouse gases emissions. Now to be fair, the countries that are now well developed did a lot of harm in the past while they were developing, so it is hard to criticize the developing countries for wanting to become richer except if they are helped in sorting out the issue.
Answer: A member of Congress might attach a rider to a bill in order to get a controversial provision in the bill get passed with the passage of the bill.
Explanation: A rider is nothing but another provision added to a bill that may otherwise be considered as a controversial bill in whole without the inclusion of the rider. The rider acts as a puller to the other controversial provisions of the bill that the member of Congress intends to get passed.
Answer:
D. magnetic polarity reversals
Explanation:
The marine magnetic anomalies are the result of two things; the seafloor spreading at the mid-ocean ridges and the magnetic polarity reversals.
The mid-ocean ridges are the places where the new crust forms. This places also have big influence on the magnetic anomalies, with the reason being that the magnetism has higher influence in this parts.
Also, the magnetic polarity reversals play a big role. The Earth has not always had the same magnetic polarity, and multiple times throughout its past the North and South Poles have been switching places when it comes to the magnetism.
The igneous rocks on the ocean floor have proof in them about this, as the metallic components are reacting to the magnetism and face toward the stronger magnetic field.
