Astudent has been measuring the oxygen levels in a lake for one year. at the end of the year she graphs he oxygen levels by month. this is an example of which step of the scientific method?

This step is called analysis.

Explanation:

Analysis is when you record observations and analyze the meaning of the data. Often, you'll prepare a table or graph of the data.

a warm, wet climate will produce the highest rate of weathering. the warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering (figure below). this happens because plants and bacteria grow and multiply faster in warmer temperatures.
