Seven years war effects and causes

Effect: The war changed economic, political, governmental, and social relations between Britain, France, and Spain; their colonies and colonists; and the American Indians that inhabited the territories they claimed. France and Britain both suffered financially because of the war, with significant long-term consequences.

Causes: In the early 1750s, French expansion into the Ohio River valley repeatedly brought France into armed conflict with the British colonies. In 1756–the first official year of fighting in the Seven Years War–the British suffered a series of defeats against the French and their broad network of Native American alliances.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
