Earth science review questions?

A student incorrectly measured the volume of a mineral sample as 83 cubic centimeters when the actual volume was 89 cubic centimeters. What was the student's approximate percent deviation (percentage of error)?





1. 6.7%


2. 7.2%


3. 9.3%


4. 14.8%








Where is metamorphic rock frequently found?





1. on mountaintops that have horizontal layers containing marine fossils


2. within large lava flows


3.as a thin surface layer covering huge areas of the continents


4. along the interface between igneous intrusions and sedimentary rocks








A student incorrectly converted 20°C to 64°F instead of 68°F. What is the student's approximate percent error?





1. 44%


2. 5.9%


3. 6.3%


4. 4%





An igneous rock contains large mineral crystals. The best conclusion to make about this rock is that it





1. contains plagioclase and pyroxene


2. is felsic and has a low density


3. once contained small crystal which eroded


4. cooled slowly as it formed

The formula for percent error is:





The accepted or actual value - the experimental value divided by the accepted or actual value.








I am not going to give you the answer, but I have given you the information to figure it out.
