Answer: Water carries nutrients to all cells in our body and oxygen to our brain. Water helps to regulate body temperature. Creation of saliva. Hydrates the skin,
It would be slightly worse than taking it off in space. The atmosphere on the surface of Mars is nearly a vacuum, so the astronaut would do well to notice the boiling saliva and tears and reseal the helmet immediately. Failing that, he or she would pass out in a few seconds, which is perhaps just as well. In space, you can only cool off by evaporation or by radiating infrared into space. On Mars, the tenuous air is just barely thick enough to conduct heat, and it’s generally colder than northern Siberia in the January. So…yeah. Don’t do that.
According to climate change scientists, the burning of fossil fuels (coal, oil, and the like) results in the releasing of carbon dioxide atoms into the atmosphere, which can cloud the atmosphere, obscuring sunlight, as well as deplete the ozone layer, resulting in an increase in global temperature. This change could potentially cause some cooler temperature-loving species to either migrate in search of cooler locations or possibly die out if they are unable to move (biosphere). It could also cause water levels in some areas to decrease due to evaporation, or increase due to the releasing of water into the oceans resulting from the melting of our polar ice caps (hydrosphere).
Hope that helped! =)
Answer:
1- Two tectonic plates separate as they are pulled apart by convection in the mantle.
2- Molten material from the mantle rises up towards the surface due to convection and fills in the rift.
3- New oceanic crust is formed.
4- The crust slowly moves away from the ridge equally on either side.
5- Overtime, the creation of oceanic crust will cause continents to move.
Explanation:
Oceanic plates get separated and the spaces left among them are filled with magma coming from the mantle. When the magma reaches the surface, it suffers physical and chemical changes at the moment it gets in touch with the cold ocean water. The magma temperature descends and turns into a new oceanic crust. Plates keep separating from each other, and the new oceanic crust moves forward each side of the crest making a place for the ascension of new fluid hot material from the mantle. This constant process is what makes the continents eventually get separated each time more.
