Earth is an active place and earthquakes are always happening somewhere. In fact, the National Earthquake Information Center locates about 12,000-14,000 earthquakes each year! This fact sheet illustrates information on the frequency of earthquakes of various magnitudes, along with details on the effects of earthquakes and the equivalent energy release.
On average, Magnitude 2 and smaller earthquakes occur several hundred times a day world wide. Major earthquakes, greater than magnitude 7, happen more than once per month. "Great earthquakes", magnitude 8 and higher, occur about once a year.

The planets in our solar system orbit around the sun. One orbit of the Earth takes one year. Meanwhile, our entire solar system – our sun with its family of planets, moon, asteroid and comets – orbits the center of the Milky Way galaxy. Our sun and solar system move at about about 500,000 miles an hour (800,000 km/hr) in this huge orbit. So in 90 seconds, for example, we all move some 12,500 miles (20,000 km) in orbit around the galaxy's center.
Our Milky Way galaxy is a big place. Even at this blazing speed, it takes the sun approximately 230 million years to complete one journey around the galaxy's center.
This amount of time – the time it takes us to orbit the center of the galaxy – is sometimes called a cosmic year.

Hitler's plan for Moscow was to kill all its residents and cover it with an artificial lake.
Hitler had some radical ideas prepared for Western Europe after he'd won World War II, but these plans were all pretty tame compared to what he had come up with for Russia and Eastern Europe. His intentions for this part of the world were merciless if not fiendish, and probably qualified as insane.

The world's most expensive spice is saffron.
Italian risotto, Spanish paella, and Indian curry all have something in common—saffron. People know the spice because of its very distinct flavor, bright color, and high price. Quality saffron can cost around $3,000 for just two pounds.
Saffron's reputation as the most expensive spice in the world is because of the growing process. Only a small part of the saffron flower—the stigmata—is actually used for the spice. So it takes some 75,000 saffron flowers to make just one pound of spice. The stigmata is delicate, so harvesting and drying them is a costly, manual job.

Strawberries are approximately 92% water.
Water makes up about 60% of the body's weight. For the body to function properly, we need to consume about two quarts of water (or liquid) per day. Every system in your body depends on water.
Water regulates body temperatures, eliminates toxins, carries nutrients and oxygen to the cells, and provides a moist environment for body tissues and joints.
Water needs vary but depend on the food a person eats, environmental temperature and humidity, a person's activity level and other factors. Fruits and vegetables contain large quantities of water in proportion to their weight. When these foods are eaten, the water can be absorbed by the body.
Strawberries contain 23 calories and are made up of approximately 92 percent water. Strawberries rank as the fourth strongest antioxidant rich fruit.The polyphenols found in strawberries aid in regulating the blood sugar response in active individuals.

Over 500 meteorites hit the Earth each year.To date, there have been nearly 1,100 recovered falls (meteorites seen to fall) and nearly 40,000 finds (found, but not seen to fall). It is estimated that probably 500 meteorites reach the surface of the Earth each year, but less than 10 are recovered. Also recently, an asteroid about 500 meters in diameter passed about 2 million km from the Earth (five times the distance to the Moon). It is estimated that each day one or two 5–10 meter objects pass within the Moon's orbit and that there are probably 30 million near-Earth objects! Most of these are too small to ever cause any damage.
