Biogeochemical Cycles
Which cycle has evaporation as a process?
What is Water Cycle
It is the first step of the scientific method, often beginning with a question inspired by an observation.
What is the problem or question?
It's the state of matter that has a definite volume but no definite shape.
What is a liquid?
Is the ph of lemon juice 3?
What is No
How does water evaporate in the water cycle ?
what is heat from the sun
In an experiment, this is the factor that is being intentionally changed or tested by the scientist.
What is the independent variable?
The ability of a substance to dissolve in another substance is an example of this type of physical property.
What is solubility?
It's the process by which atmospheric CO2 is converted into organic compounds by plants, a crucial step in this cycle.
What is photosynthesis?
This final step of the scientific method is where you analyze the data and determine whether your hypothesis was correct.
What is the conclusion?
This phase change occurs when a liquid turns into a gas, such as when water boils.
What is vaporization or boiling?
Does water have a ph of 7?
What is yes
This element, which makes up about 78% of the atmosphere, needs to be converted by certain bacteria into a usable form for most living things.
What is nitrogen?
This is a well-substantiated explanation of some aspect of the natural world, acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation.
What is a scientific theory?
A pure substance that cannot be broken down into simpler substances by ordinary chemical means.
What is an element?
A substance with a pH of 7 on the scale, like pure water, is described as this.
What is neutral?
Unlike other major biogeochemical cycles, this one lacks a significant atmospheric phase and is primarily found in rocks and sediments.
What is the phosphorus cycle?
This is a control group's purpose: it provides a baseline to which you can compare the results of your experimental group.
What is a standard of comparison?
The ability of iron to rust is an example of this type of property, which can only be observed when the substance undergoes a chemical change.
What is a chemical property?
This type of substance has a pH less than 7, turns litmus paper red, and tastes sour.
What is an acid?
