Aerodynamic
An aerodynamic design reduces air resistance, which in turn increases fuel efficiency and top speeds. These designs often feature curved, rounded surfaces rather than flat ones because the air can pass over a sleek shape with less resistance.
Cahulawassee River
Once a popular destination for canoeing, this river in the remote back hills of Georgia vanished when the valley it flowed through was flooded to make way for the construction of a dam.
Cubic Feet
A cubic foot is an American unit for measuring volume. It is defined as an area that is 1' long, by 1' wide, by 1' deep.
Cumulonimbus
Also know as thunderstorm clouds, these big, billowy masses form large, vertical columns that look like anvils. When you see a patch of Cumulonimbi forming, try and avoid trees and tall towers–lightning often accompanies these fluffy monsters.
Drag
Drag is the word for air resistance that slows down your vehicle while driving. The effect is more pronounced at higher speeds. Drag is reduced by aerodynamic shaping such as curved edges that reduce the air caught by your vehicle.
An Eskimo roll is a kayaking maneuver that experienced riders use to flip their capsized boats without having to leave their seat.
