Thermal protection - water at depth can be very cold.
Both astronauts and sea divers wear special sits because they travel into atmospheres that are strange to our bodies. Our bodies were not built to stand extremely deep waters and outer space. The suits protect them as they go about their business in those places.
Free divers do but scuba divers do not need to. Scuba divers take their air with them and would have no need to hyperventilate.
they need to know how long they can be underwater, and how deep they can go with the air in the tank.
What they wear depends on what events they are competing in. Most athletes wear modern athletic attire that can include warm up suits, shorts and tanks.
for protection, as astronauts need to wear space suits to do space walks. Humans are fragile beings. Our skeletons and bone structure can only work in a narrow range of pressure around the atmospheric pressure [~1x105 Pa at sea level] -- we have adapted to earth's atmosphere. In deep seas, the human body will encounter a pressure [Pa], in addition to atmospheric pressure, equals to rho*g*h, where rho = water density [~ 1000 kg/m3]; g = 9.8 [m/s2]; and h is the water depth [m].
Deep sea divers wear diving suits in order to prevent their body by the harmful effects of maximum pressure at greater depth in seas and ocean.
Because fish have gills,giving them the ability to breath under water and divers dont.
Special suits, like wetsuits or drysuits, are essential for underwater activities because they provide thermal insulation, protect against cold water, and shield the body from abrasions and marine life. Wetsuits allow a thin layer of water to be trapped between the suit and the skin, which warms up with body heat, while drysuits keep the wearer completely dry by using an airtight seal. Additionally, these suits often have buoyancy control features, enhancing safety and comfort during dives. Overall, they help ensure divers can safely explore underwater environments.
We need air to breath. Otherwise we would suffocate and die. That is why scuba divers have special equipment to allow them to have air to breath underwater.
Yes, astronauts wear specialized clothing while living and working inside the space station. They wear comfortable clothes for daily activities and special space suits for spacewalks or emergencies. These suits provide protection from extreme temperatures, radiation, and microgravity conditions.
In "The Great Waldo Search," the scroll on the Deep Sea Divers page is located near the bottom right corner of the scene. It is partially obscured by some seaweed and a diver, so players may need to look closely to spot it. Make sure to check around the various sea creatures and objects for a clearer view.
