Is exploring space important?
Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system. Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations.
Is the ocean more important than space?
The ocean is critical to human life—more than 50 percent of the oxygen we breathe comes from it. We believe ocean exploration is more exciting and more important than space exploration. Yet it only receives about one-one hundredth as much funding.
What is in the deepest ocean?
The average ocean depth is 2.3 miles . The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.
What are the 2 main reasons for the development of ocean currents?
Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.
What are deep currents caused by?
In contrast to wind-driven surface currents, deep-ocean currents are caused by differences in water density. The process that creates deep currents is called thermohaline circulation—“thermo” referring to temperature and “haline” to saltiness.
What would happen if the ocean circulation stopped?
The ocean currents carry warmth from the tropics up to these places, which would no longer happen. If the currents were to stop completely, the average temperature of Europe would cool 5 to 10 degrees Celsius. There would also be impacts on fisheries and hurricanes in the region.
What are the causes of currents?
Causes of Ocean Currents
- Solar heating. it causes water to expand.
- Wind. The Wind is responsible for ocean currents as it blows the water on the surface, causing the currents.
- Gravity. Gravity tends to pull items towards the surface of the earth.
- The salinity of the water.
- Temperature.
- Coriolis effect.
- Underwater earthquakes.
What is the strongest current in the ocean?
Antarctic Circumpolar Current
Why can’t Mars have oceans?
No large standing bodies of liquid water exist on the planet’s surface, because the atmospheric pressure there averages just 610 pascals (0.088 psi), a figure slightly below the vapor pressure of water at its triple point; under average Martian conditions, warming water on the Martian surface would sublime meaning …
What is the longest current in the world?
How fast is the EAC current?
about 5.6 miles per hour
Do turtles actually ride the EAC?
New research has revealed that the EAC plays a critical role in transporting turtles between habitats across the southern Pacific Ocean. Nesting female sea turtles show a high degree of fidelity to their natal beaches; as a result, turtles hatched in the same place bear the same genetic signatures.
Does EAC exist?
The East Australian Current (EAC) is the southward western boundary current that is formed from the South Equatorial Current (SEC) crossing the Coral Sea and reaching the eastern coast of Australia. At around 15° S near the Australian coast the SEC divides forming the southward flow of the EAC.
What animals ride the EAC?
Aussie turtles ‘ride the EAC’ to Peru.
