<span>Alright.. this is what I have in mind... then you can judge if I'm totally crazy:
As in any other experiment we wish to only hold 1 variable, while other thinkable variables are held constant.
In addtion to that we need to ref. soil and call that 0.
Now some theory: We know from medicals they can have synergetic effect if mixed. Same can go for nutrients, we therefor test each soil mixed and alone and see the effect.
We call the nutrients A, B and C, (continue with more if you like)
Now this is our setups:
0, A, B, C, AB, AC, BC, ABC.
In this way we can make compare to a ref soil (0) and also check for synergetic effects... this is a bit considered a multivariable experiment, but we also have A, B and C as ref. against the mixed soils.</span>
The formation of an atoll is a slow process that can take millions of years. It begins when an underwater volcano erupts, creating a buildup of lava on the seafloor. With continued eruptions, the lava continues to build until it breaks through the ocean's surface and forms an island.
Answer:
The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time.
Answer:
Birth rate.
Explanation:
Countries such as Japan are dealing with a low Birth Rate, meaning the population is aging due to the lack of births to lower the average age.
Earthquakes and tsunamis are caused by pressure building up in the Earth's crust along the intersection of tectonic plates, while tornadoes are created by updrafts and downdrafts interacting with wind.
