facts about planet earth
Astronomy enthusiasts are always looking for facts about planet Earth, from discovering the nature of the Earth in which they live, and realizing all the facts and how true some of the myths circulated by some social media pioneers from time to time, which prompted many technology users to search again and again for those facts. Common and controversial.
facts about planet earth
There are facts about the planet that are difficult to enumerate, so we monitor the most prominent of them through the following report, according to the “live science” website.
Occupying the third place among the planets
It comes on top of facts about planet Earth, that it occupies the third planet from the sun, and the only world known to support the atmosphere with oxygen, and it covers large areas of oceans, seas and rivers on the planet’s surface, and it is also one of the four terrestrial planets, according to NASA, on the Like Mercury, Venus and Mars, it is distinguished by its rocky surface.
the earth is moving
The second thing about planet earth facts is that you feel like the earth around you isn’t moving, but that you’re constantly moving. Depending on where you are on the globe, you can spin with the planet at just over 1,000 miles per hour.
People on the equator move faster, while a person standing at the North or South Pole would be completely stationary, the way a basketball rolls on your finger. A random point on the equator has farther to travel in one turn than a point near your finger, Thus, the point on the equator is moving faster.
The planet moves around the sun
The Earth revolves around the sun at 67,000 miles or 107,826 kilometers per hour, according to the American Physics Association.
Earth is billions of years old
Researchers calculate the age of the Earth by dating both the oldest rocks on the planet and meteorites that have been discovered on Earth. To teach science.
Planet Earth is being recycled
The planet you walk on is recycled, as the terrestrial rock cycle turns igneous rocks into sedimentary rocks into metamorphic rocks and back again. The cycle isn’t a perfect circuit, but the basics work like this, magma emerges from deep in the earth and solidifies into rock, and that’s the volcanic part.
Tectonic processes raise these rocks to the surface, where erosion attaches small parts, and these small fragments are deposited and buried, and pressure is made from above in sedimentary rocks such as sandstone, and if the sedimentary rocks are buried deeper, they are represented in metamorphic rocks under a lot of pressure and heat .
Of course, sedimentary rocks can be re-eroded or metamorphic rocks re-uplifted, but if metamorphic rocks get stuck in a subduction zone, where one piece of crust pushes under the other, it may find itself turning back into magma.
moon earthquakes
Earth’s moon looks dead and inactive, but quakes on the moon actually make things shake up a bit, and quakes on the moon are less common and less intense than earthquakes that shake the Earth, according to the Encyclopedia of Physical Science and Technology, the total seismic energy released by the moon is about 80 times less than those emanating from the earth.
According to the Journal of Geophysical Research, lunar earthquakes appear to be related to tidal pressures related to the changing distance between the Earth and the Moon, as lunar earthquakes also tend to create great depths approximately midway between the surface and center of the Moon.
