Seven Things About Our Planet Earth

As usual here are Seven things about the Earth you never knew.



EXPLOSIVE FACTS
An amazing feature of the earth is that it has almost 500 volcanoes worldwide. About 80% of the earth, that which is found above and below the surface, are made of volcano soil.

THE COLOUR OF THE EARTH
The earth is popularly dubbed as the blue planet. Astronauts who first went to space described the entirety of earth as blue. This is due to the fact that 71% of the planet is covered by bodies of water.

THE EARTH IS HOT
Aside from the sun as earth's main source of heat energy , humans could theoretically survive without the sun's heat as the planet's inner core is hot enough to supply energy to its inhabitants. It is estimated that the core temperature is between 5,000 to 7,000 degrees Celsius. It's just as hot as the sun's surface too!

UNIQUE TECTONICS
Planet earth is the only planet of the milky way which features tectonic plates.

SPACE DUST
 There are approximately 30,000 space particles and dust that enter the earth's atmosphere annually. Fortunately, the majority of this debris burns up when it enters the earth's atmosphere ,resulting in shooting stars instead of giant craters.

SPEEDS OF EARTH
The earth surface rotates on it's axis at 1,000 miles per hour. Consequently, the planet travels through space at 66,700 miles per hour. But how come we do not feel that our planet is moving at a dizzying rate? This is due to the fact that the earth is rotating at a constant speed and is partly due to the gravitational pull of earth.

THE BRIGHTEST OF THEM ALL
Although it is known that Venus is the brightest celestial body in the sky, earth is comparatively brighter when observed from outer space. The factor which makes our planet brightest among all the planets of the milky way is water. The oceans which cover almost 71 percent of the earths surface, contain close to 20 million tons of gold.
