Explain why.2.Seamounts are either active or dormant volcanoes that rise dramatically from the bottom of the ocean and never reach the surface. They are hotspots for marine life because they carry nutrient-rich water upward from the sea floor. Seamounts are believed to cover about1 million s!uare miles of the planet. hat conclusion can be drawn from this passa#e$%.%. &o you thin' underwater exploration is a valid use of scientific funds$ hy does this type of exploration matter to us$1. The part when they #o to the seamount is scientifically valuable since they collect data (ima#es) s'etches) drawin#s* to help answer !uestions. They may also have collected samples of the water and species livin# there. 2. + can conclude that most of the world is covered by volcanoes. hich is #ood since they help marine life by providin# nutrient-rich water.%. + thin' it is valid since science is where you as' a !uestion and answer it) as'in# yourself what,s under water and findin# out what is really there is science. +t helps answer !uestions that need to be answered.
