What principle did the studies of James Hutton and Charles Lyell contribute to? Horizontality, which states that if sedimentary rocks are not found in horizontal
layers, they have been rearranged by the forces within Earth.
Superposition, or the fact that older rock layers are found below newer rock
layers in undisturbed sedimentary rock.
Uniformitarianism, or the fact that geological processes have always operated in
a similar way for the entire history of Earth.
Unconformities, which states that folding, tilting, erosion, or other breaks in the
rock record can provide clues to Earth's past.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

answer; the correct answer is conflict- related aggression; +

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
