Iron ore consists mainly of iron atoms and oxygen atoms joined to each other to form several different possible forms of iron oxide. Which branch of physical science MOST directly deals with developing ways to remove the oxygen from iron oxide, thus leaving iron metal? - -earth science Which field of physical science MOST directly explains how the motion of the continents over 100 million years led to mountains and volcanoes in some places above land, and deep ocean trenches in other places beneath the ocean surface? - -Earth Science Which type of scientific study is BEST suited for collecting data that will be used to analyze statistical information about the kinds of meanders, or turns, in the path of rivers such as the one shown in the photograph below? Image of a rock arch formed by wind and rain. - -field study Geckos, like the one shown here, are known for being able to walk on very smooth surfaces, even upside-down. Tiny ridges on the gecko's feet allow it to stick to a smooth glass surface because of weak forces between the atoms in the gecko's foot and the atoms in the glass. Which two fields of physical science would be MOST relevant in investigating how a gecko sticks to glass? - -physics & chemistry A scientific procedure done in order to test a hypothesis is a(n) - -experiment While on a hiking trip, several children become sick after drinking water from a well. Which of the following is a hypothesis concerning this situation? - -Bacteria in the well may have caused the sickness
