This presentation will provide a review of CMEs: (1) intrinsic properties set at the Sun (e.g., orientation, trajectory, acceleration, etc.), (2) processes that may occur during propagation (e.g., shocks, compressions, magnetic erosion, etc.), and (3) in the specific interaction with Earth's magnetosphere (e.g., preconditioning mechanisms) that can have a significant influence on their geo-effectiveness. Their relative importance will be discussed.
