    1. The problem statement, all variables and given/known data

    Name a strength and weakness of each technique.

    2. Relevant equations

    3. The attempt at a solution

    The two techniques that I came up with are:

    Magnetic Line of Force in rocks to analyze land-based paleomagnetic data.
    Strength: Well, it's easy to collect. [need help here]
    Weakness: Data collected by this method results in a loss of data as we do not acquire east/west data but only north/west data.

    Geomagnetism --> To measure magnetic anomalies of the sea-floor. This was marine based data.
    Strength: We get exact results as the information is hard-coded into the seafloor.
    Weakness: Don't have a good idea yet. I initially said that the data was difficult to collect, but that isn't the answer we were looking for. [help here?]

    What is "Earth data"?

    :P I didn't have room in the title to properly demonstrate what I needed. But by the title, I mean, We are looking at each method for strengths/weaknesses to collect data sets for movement of the india plate.

    Regarding a weakness of paleomagnetism think in terms of plate tectonics and how that affects the oceanic crust.
