The Coriolis effect (also called the Coriolis force) is defined as the apparent deflection of objects (such as airplanes, wind, missiles, and ocean currents) moving in a straight path relative to the earth's surface.s latitude increases and the speed of the earth's rotation decreases, Coriolis effect increases. A pilot flying along the equator itself would be able to continue flying on the equator without any apparent deflection.
LOUISIANA PURCHASE. LOUISIANA PURCHASE. A watershed event in American history, the purchase of the Louisiana Territory from France in 1803 nearly doubled the land mass of the young nation: for a purchase price of $15 million, the United States increased its size by some 828,000 square miles.
The Louisiana Purchase of fifty years earlier, the biggest land sale in history, had transferred an area of 827,000 square miles between the Mississippi and the Rocky Mountains from theoretical French sovereignty to the United States.
