Approximately 5 of the Earth's oceans have been explored by humans, while a larger portion of the land has been explored.
Um... yes. Humans pretty much have explored all the Earth's oceans. I get the feeling you were trying to ask a question to which the answer is less obvious.
As of now, approximately 80% of the Earth's land surface has been mapped and explored to some extent, but much of this exploration is superficial and does not account for detailed scientific study. Vast areas, particularly in remote regions like deep oceans, dense forests, and polar regions, remain largely uncharted or poorly understood. Additionally, many areas have not been thoroughly studied for their biodiversity or geological features. Thus, while humans have physically traversed much of the world, significant gaps in knowledge and understanding still exist.
Within Carlsbad Caverns itself, about thirty miles of tunnels have been explored. Within the park is Lechuguilla Cave, which is much longer at 138 explored miles.
I do not know too.
Being the longest cave explored (350 miles)
Approximately 15%.
I live on Earth, as do all other humans. Where are you from?
They are not needed at all, the earth would be much better place without them...
as much as humans on the earth
Atoms existed long before humans. Atoms are the basic building blocks of matter and have been present in the universe for billions of years. Humans, on the other hand, evolved much later in Earth's history.
None has been found yet, but it may still be found in the future - not much of space has been explored yet.
Animals reproduce much faster than humans and have more children at one time.
