Words Sparking Curiosity

I have been provided with several terms: places, trends, things, technologies, people, controversies, history, jobs, habits, and hobbies. Choosing four terms, I have been instructed to write down anything that comes to mind when I think of that term, no matter how crazy or random it may be.

PLACES: Amazon, forests, palaces, deserts, poverty, war, religious conflict, middle-east, Paris, boxes, my room, classrooms, libraries, what long term effect does salt have on skin?, the beach, seaweed
THINGS: yo-yo, pencils, health and medicine, flowers, sidewalks, city life, foreign languages, acceptance of foreign customs,black holes, myth versus fact, how much of the ocean has been explored?, what's the truth about the Bermuda Triangle?, How do people become known in the music business?
PEOPLE: Obama, Prime Ministers, terrorism, teachers, lock-downs, globe, the earth, interaction between the continents, allies, inventors, scientists, historians, archaeology, empires, how far away is cancer from being cured?, what science investigations are going on currently?
TRENDS: Twitter, Instagram, Seventeen Magazine, Sheetz, sports, World Cup, violence in sporting games across the world, Facebook, bookstores, caramel, Starbucks, effect of caffeine on teens and children.

The most promising item I found in my list may be "How much of the ocean has been explored?" I can expand from just the ocean to other parts of the world and uninhabited islands. This can spark scientific research as well, and the findings from what is explored can be answers to questions. Some people may be against exploring the unknown, while others may see the many benefits in it.

I have generated a list of questions for this topic:
What percentage of the ocean has been explored?
How many decently-sized islands could be waiting for discovery?
What groups or organizations go out and explore oceans or other parts?
What professions incorporate exploration?
How dangerous could it be?
What precautions should be taken before going out on an expedition?
How does a group determine whether to go out professionally exploring, or not?
What materials are needed?
Are there first aid services nearby?
Could groups go out exploring to search for an answer to a scientific question?
What scientific mysteries require more exploration?
How far are Americans allowed to explore on foreign lands?
How far can they go until they have disobeyed some type of law?
