There are lots of caves were the air is dangerous to breath but is not toxic to the skin. So you only need to furnish your own air to explore the cave. A cave explorer could use what the miners use in an emergency, for when they are cut off from the entrance.
No, hamsters cannot scuba dive because they are not adapted for underwater breathing. Their respiratory system is not designed for underwater environments, and they would drown if submerged in water for an extended period of time.
I would call it the Great White Pucker Factor.
I would say scuba diving. You can get the bends, or nitrogen narcosis. There is also the factor of running out oxygen during a dive.
Oceanography is like geography in the sea. You study the geography of the seabed and the nature of the water, such as salinity, turbidity currents etc. Although oceanographers may like scuba diving it is unlikely that is will be part of their job because using SCUBA you can only visit a tiny amount of the oceans. Lots of oceanographers are involved in oil exploration for example where the water would be far to deep to reach with scuba.
The Noble of gas of helium (He) allows for the Goodyear Blimp (an airship) to rise. Helium (heliox) mixtures also allow for deep scuba diving.
Me.
Becasue if a SCUBA diver didn't go underwater, they really wouldn't be a SCUBA diver. SCUBA stands for Self-Contained Underwater Breathing Apparatus.
Fins provide much greater force in water than your bare foot, due to the increased surface area. This increased force is necessary because the additional equipment needed for scuba diving (tank, buoyancy compensator, regulators, etc...) increases the amount of drag and weight of your body in the water. Without fins, you would use a great deal of energy and not get very far.
No. For as big as the whale shark is, the esophagus is only about he size of a QUARTER! So the whale shark would NOT be able to eat the scuba diver.
Yes. It would be more comfortable if it covers the nose as well. You can dive without a mask, but you would find it difficult to see and you wouldn't be able to read your instruments. Plus it wouldn't be very comfortable especially if diving in salt water
While scuba is an acronym, it is no longer necessary to capitalize every letter of the word.I would like to upgrade my scuba gear.
The costs for a good scuba mask ranges about $50 to $70
