What does modality refer to? How does it appear on ER diagram? - ANSWERRefers to the MINIMUM number of times an instance in one entity can be associated with instance of another entity (minima) Appears as a 0 or 1 on the relationship line, next to cardinality Define: Referential Integrity - ANSWER- Requires that ALL foreign key values must either be fully NULL or match some primary key value 4 Ways Referential Integrity can be violated: - ANSWER- 1. Primary key is updated 2. Foreign key i...

Employee Assistance Programs | EAPS 100 Final Exam Which of the following atmospheric layers is where weather occurs? Troposphere Solar radiation transmits energy to the Earth's surface. True Solar radiation can be absorbed by the Earth's surface or reflected back into space. The ratio of reflected radiation to absorbed radiation is known as albedo. Which of the following surfaces has the highest albedo? Glacial Ice Asphalt Road Ocean Forest Canopy The Earth's surface absorbs solar radiatio...
