Longitudinal studies are carried out over the period of time. A cross sectional study is a one contact program with the target population having the outcome but the longitudinal study needs a constant follow up with the sample. A cross sectional study is conducted at a given point in time.
Some cross sectional studies take place regularly each time including a large number of repeat questions. Longitudinal studies may vary from a few years to even decades. A longitudinal study requires a researcher to revisit participants of the study at proper.

Cross sectional studies allow the researcher to look at one independent variable as the focus of the cross sectional study and one or more dependent. It provides a snapshot of the situation.
