Gas molecules in the air absorb energy from the sun, or from the energy that is absorbed and re-radiated by materials in the Earth's surface. The molecules gain kinetic energy and the temperature of the air rises. They also gain energy when they bump into, and share, the kinetic energy of other molecules. We need it for survival. Too much of a good thing causes problems.
Statistics often support environmental decision-making.
In fieldwork you sampled local areas using transects and quadrats. Transects are lines and quadrats are areas you hope represent the whole area. You may have counted a higher or lower proportion of a species than is truly the case. Conclusions may be problematic. Suppose three classmates say they never eat chocolate.
