Surface craters refers to a short-term environmental change would a very small asteroid or comet impact on Earth most likely cause.
Experimenting. Experimenting is used in all three main branches of science, physics, chemistry, and biology, and is used in all the sub-branches of science, like marine biology, to make discoveries. Without experimenting, all we know about science would be random guesses.
I think the answer is organisms
I actually had a similar question on my test and this is the answer:
The reason the magnet loses its magnetic properties is is because when you drop the magnet or bump it against something, the domain can get bumped or dropped out of alignment.

The same way we never inject a full bag of anything quickly and intravenously. Your body would not be able to compensate for the amount of the substance. Alcohol or more importantly the Ethanol or Ethyl Alcohol in alcoholic beverages is the active ingredient of such beverages. It is also a drug called a CNS (Central Nervous System) depressant which means it is in the same class category of Opioids (Such as Heroin and Morphine) and Barbiturates (Rophynol). Your body processes alcohol via the liver, as it is also considered a toxin. By consuming a massive amount of alcohol without spacing it out, you will overload your system, not only literally overwhelming your liver and causing Alcohol Poisoning, but you also can go into a state similar to a Heroin overdose.
