Scientists are able to understand the earth's interior by studying these seismic waves. They are waves of energy that travel through Earth, and actually move similarly to other types of waves, like sound waves, light waves, and water waves.

Answer: A group of scientists wants to determine whether a relationship exists between alcohol consumption and certain types of cancer. To this end, scientists provide study participants with a questionnaire asking them how many alcoholic drinks they have per week and what diseases they have (if any). These scientists provide subjects with a similar questionnaire annually (for a decade). These scientists are performing an ASSOCIATION STUDY.
Explanation: Association study is observational study in different individuals to see if a particular behavioral pattern (such as alcohol consumption) can be associated with certain type of disease (such as cancer).
Information collected from the questionnaires distributed will be subjected to statistical analysis and conclusion(s) will be made.
