Earth Science Measurement Notes
SI Units • Metric system • Numbers based on a unit of 10
Base Units • Length • SI unit meter (m) • Measuring Distance • Weight and Mass • Weight is gravitational force and can change (Earth and Moon) • Mass is amount of matter in an object • SI Unit of mass kilogram (kg)
Units • Area • Amount of surface • Combination of lengths (length and width) • SI Unit is meter squared (m2) • Volume • Amount of space an object takes up • Solid (length x width x height) • SI Unit meters cubed (m3) • Liquid measured in Liters (L)
Units • Density • Amount of matter that occupies a given space • Mass/Volume (g/ml) or (g/cm3)
