EARTH ENVIRONMENTAL STUDY GUIDE KEY Intro Unit The branch of earth science that deals with the Earth’s history and structure is called? Geology Can a metric ruler be used to find the volume of a regular solid? If so, HOW? Yes. Length X width X height Can meters be used to measure the volume of a liquid? If so, HOW? Yes 1 mL = 1 cm3 A unit for density is g/L. Give an example of how this information can be used. The mass of an object divided by the volume ; D = m/v If we were to measure the distance from Charlotte to Mobile, AL, what metric unit of measurement should we use? km Oil floats on top of water. What does this mean with regards to its DENSITY? Oil is less dense than water. Can meters be used to measure the volume of a liquid? If so, HOW? Yes 1 mL = 1 cm3 Identify and describe the steps of the Scientific Method? What would a scientist do to test a hypothesis? Determine the independent and dependent variables. Control as much as possible. Recorded observations or measurements are called data and can be displayed…HOW? Quantitatively (Numerical in a chart) or Qualitatively (in descriptive words) At the end of an experiment, a scientist forms a conclusion. A visual display of data or information is called a Graph For statements A-D, determine which step in the scientific method is being described. Hypothesis A.
