Answer:
1. Most Submarines are created solely for military purposes
Submarines according to the text, are created primarily for warfare with their main weapons being torpedoes that are like mini self-propelled submarines carrying an explosive charge.
2. Submarines either rise or submerge by displacing water.
Submarines use the Archimedes principle which works by displacing water that weighs more than the boat to rise.
3. Some submarines are used for Oceanic Exploration
Some or at least 1 at that moment being the Argonaut was built for oceanic exploration and is equipped with diving appliances and equipment to enable it save wreckage.
4. All submarines must be sure not to descend too far underwater.
Every submarine has a limit in terms of the depth it can submerge to and it should not go beyond this point. Water bodies have their pressure in them as sink deeper and if the submarines go beyond the point where the submarine can no longer withstand the pressure it will be battered.
The answer is B textual evidence. Hope this helps! : D
[] Answer(s) []
Disposal to landfill
Thermal treatment
[] Explanation \ Reasoning
Disposal to landfill is also known as a dump. When you take your trash or garbage to a garbage dump, you probably wonder what they do with it. Well, they take it away then throw it over an edge to never be dealt with again. There are heaps upon heaps of just trash from us humans. They don't burn it, bury it, or anything else. They just let it sit there. People are all against littering, but this is beyond littering. We are ruining our environment when we do this.
Thermal treatment is the way we use heat to get rid of our garbage. These methods of thermal treatment include: Incineration, Gasification and Pyrolysis and open burning. For example, instead of dumping or burying our trash, we burn it. This is not good for the air or for the earth. We pollute ourselves and our air when we do this. People burn their trash in their backyard, not even at a burning site. This is extremely bad.

Answer:
"curr"

The root curr is easily recalled via an ocean current, which “runs” by itself since it is surrounded by waters that are relatively still.
