Why do scientists usually look at average speed instead of specific speed in labs?
1. averages take care of some of the errors in data OR
2. it takes into account stops and starts, slowing and speeding

Describe the energy transfer that takes place as a person rides a bicycle up a hill and down the other side.
Potential energy builds as the person gets to the top of the hill. Potential energy transfers to kinetic energy as the bicycle goes over the top of the hill. Kinetic energy builds as the person approaches the bottom of the hill.

Minerals, such as quartz, calcite, and even diamonds, naturally form in different colors.
What is the difference in the formation of each mineral that could change its color?
Chemical Impurities

Why are fossils rarely found in metamorphic or igneous rocks?
Heat and pressure destroy the structure of the fossils.
