因いん果が
因果関係 is the precise technical term for a 'causal relationship', while 因果 alone can be used more loosely for causality or even karma/fate.
因いん果が律りつN1
因果関係 describes a specific causal connection between events, while 因果律 is the abstract philosophical law that every event must have a cause.

相そう関かん関かん係けい
因果関係 means a direct cause-and-effect link, while 相関関係 only means two things vary together without necessarily one causing the other.

Compound of 因果 (cause and effect) and 関係 (relation). The term is a straightforward Sino-Japanese construction.
