C. The French and American Revolutions were caused by a growing middle class. The middle classes in both societies were well educated and growing in wealth due to global trade and commerce. However, due to the monarchical rules, land owners typically received more benefits. The middle class was left with little to no voice in the government yet money to be taxed.
Haiti was a slave-led revolt leading to independence from France. Brazil was a peaceful negotiation giving Brazil independence from Portugal. Mexico was a poor/lower class movement to gain independence from Mexico. Leadership for the Mexican revolution were educated in American government and were middle class however.
Earthquakes and land drifting is caused by the movement/shifting of tectonic plates.
