2 or dioxygen. Ozone is formed from dioxygen by the action of ultraviolet light and also atmospheric electrical discharges, and is present in low concentrations throughout the Earth's atmosphere (stratosphere). In total, ozone makes up only 6993600000000000000â 0.6 ppm of the atmosphere.
Of the many car driving tips that might be offered, this one isn't intuitive-accelerate through curves to gain better traction. It seems that acceleration on a curve would cause a vehicle to loose traction and fishtail. It does if you apply too much, but limited acceleration improves traction when taking a curve.
The Moon's speed through the shadow during a lunar eclipse is about one kilometer per second (2,300 mph) and I suppose that would be the speed of its shadow on Earth too. As the earth continues to rotate, the umbra sweeps across the surface from west to east at a speed of about 1600 kilometers an hour.
