Activity diagrams :
are typically used for business process modeling,
for modeling the logic captured by a single use case
or usage scenario, or for modeling the detailed logic
of a business rule. This is the OOAD version of flowchart
or data flow diagram.

Sequence Diagrams:
model the flow of logic within your system in a visual manner,
enabling you both to document and validate your logic,
and are commonly used for both analysis and design purposes.
Sequence diagrams identify behavior within the system.
