TOP 10 AMAZING FACTS ABOUT ORB EARTH

ORB EARTH. THAT GLOSSY BLUE STONE THAT HAS CAPTIVATED HUMANKIND SINCE THEY FIRST INITIATED TO TRAVEL OVER ITS SURFACE. AND WHY SHOULDN’T IT CAPTIVATE US? IN ADDITION TO BEING OUR HOME AND THE PLACE WHERE LIFE AS WE KNOW IT CREATED, IT REMAINS THE ONLY ORB WE KNOW OF WHERE LIFE FLOURISHES. AND OVER THE COURSE OF THE PAST FEW GENERATIONS, WE HAVE LEARNED MUCH ABOUT ORB EARTH, WHICH HAS ONLY DEEPENED OUR INTENSIFIED WITH IT.

BUT HOW MUCH DOES THE ORDINARY HUMAN REALLY KNOW ABOUT THE EARTH? YOU’VE LIVED ON EARTH ALL OF YOUR LIFE, BUT HOW MUCH DO YOU ACTUALLY KNOW ABOUT THE LAND BENEATH YOUR PAW? YOU POSSIBLY HAVE LOTS OF EXCITING FACTS IN YOUR MIND, BUT HERE ARE 10 MORE FASCINATING FACTS ABOUT PLANET EARTH THAT YOU MAY, OR MAY NOT.

1. PLATE TECTONICS KEEP THE PLANET EASY:

EARTH IS THE ONLY ORB IN THE SOLAR SYSTEM WITH PLATE TECTONICS. FUNDAMENTALLY, THE EXTERNAL CRUST OF THE EARTH IS FRAGMENTARY UP INTO REGIONS KNOWN AS TECTONIC PLATES. THESE ARE AMBULATORY ON TOP OF THE MAGMA INTERIOR OF THE EARTH AND CAN MOVE AGAINST ONE ANOTHER. WHEN TWO PLATES BUMP INTO, ONE PLATE WILL SUBTRACT (GO DOWN ANOTHER), AND WHERE THEY PULL APART, THEY WILL ALLOW THE NEW CRUST TO FORM.

THIS PROCEDURE IS VERY NECESSARY, AND FOR A NUMBER OF COUSE. NOT ONLY DOES IT CONDUCT TO TECTONIC REBUILD AND GEOLOGICAL ACTIVITY (I.E. EARTHQUAKES, VOLCANIC ERUPTIONS, MOUNTAIN-BUILDING, AND OCEANIC TRENCH CREATION), IT IS ALSO ENORMOUS TO THE CARBON CYCLE. WHEN MICROSCOPICAL PLANTS IN THE OCEAN DIE, THEY FALL TO THE BASE OF THE SEA.

OVER LONG TERM OF TIME, THE RELICS OF THIS LIFE, RICH IN CARBON, ARE TAKE AWAY INTO THE INTERIOR OF THE EARTH AND REDUPLICATE. THIS MAGNETIZES CARBON OUT OF THE ENVIRONMENT, WHICH MAKES SURE WE DON’T TOLERATE A FUGITIVE GREENHOUSE EFFECT, WHICH IS WHAT HAPPENED ON VENUS. WITHOUT THE FUNCTION OF PLATE TECTONICS, THERE WOULD BE NO WAY TO REDUPLICATE THIS CARBON, AND THE EARTH WOULD BE AN OVERHEATED, SULFUROUS PLACE.

2. EARTH IS APPROXIMATELY LIKE A SPHERE:

MOST OF THE PEOPLE TEND TO THINK THAT THE EARTH IS A SPHERE. ACTUALLY, DURING THE 6TH CENTURY BCE AND THE MODERN TIME, THIS STAY THE SCIENTIFIC CONSENSUS. BUT THANKS TO RECENT ASTRONOMY AND SPACE JOURNEY, SCIENTISTS HAVE SINCE COME TO KNOW THAT THE EARTH IS REALLY SHAPED LIKE A FLATTENED SPHERE (AS AN OBLATE SPHEROID).

THIS SHAPE IS EQUAL TO A SPHERE, BUT WHERE THE POLES ARE OBLATE AND THE EQUATOR BULGES. IN THE CASE OF THE EARTH, THIS BULGE IS DUE TO OUR PLANET’S STAGGERING. THIS MEANS THAT THE SIZE FROM POLE TO POLE IS ABOUT 43 KM LESS THAN THE DIAMETER OF THE EARTH ACROSS THE EQUATOR. EVEN THOUGH THE LONGEST MOUNTAIN ON EARTH IS MOUNT EVEREST, THE SYMPTOM THAT’S FURTHEST FROM THE CENTER OF THE EARTH IS ACTUALLY MOUNT CHIMBORAZO IN ECUADOR.

3. EARTH IS CHIEFLY IRON, OXYGEN, AND SILICON:

IF YOU DETACHED THE PLANET EARTH OUT INTO PILES OF SUBSTANCE, YOU GET 32.2 % IRON, 30.2% OXYGEN, 15.2% SILICON, AND 13.6% MAGNESIUM. SURELY, A MAJOR PART OF THIS IRON IS ACTUALLY STATIONED AT THE CORE OF THE EARTH. IF YOU COULD ACTUALLY GET DOWN AND SPECIMEN THE CORE, IT WOULD BE 88% IRON. AND IF YOU SAMPLED THE EARTH’S SCAB, YOU’D DISCOVER THAT 47% OF IT IS OXYGEN

4.  EARTH’S 70%  LEVEL IS HIDDEN IN WATER:

WHEN ASTRONAUTS FIRST WENT INTO THE SKY, THEY VIEW BACK AT THE PLANET EARTH WITH HUMAN EYES FOR THE FIRST TIME. BASED ON THEIR EXPERIENCE, THE EARTH OBTAINED THE NICKNAME THE “BLUE PLANET: AND IT’S NO WONDER, SEEING AS HOW 70% OF OUR PLANET IS HIDDEN WITH OCEANS. THE REST 30% IS THE HARD CRUST THAT IS STATIONED AT SEA LEVEL, HENCE WHY IT IS CALLED THE “CONTINENTAL CRUST”.

5. THE EARTH’S ENVIRONMENT EXTENDS TO A DISTANCE OF 10,200 KM:

THE EARTH’S ENVIRONMENT IS WIDEST WITHIN THE FIRST 50 KM FROM THE BOTTOM LEVEL, BUT IT ACTUALLY EXPANDS OUT TO ABOUT 10,200 KM INTO THE SKY. IT IS CONSTITUTED UP OF FIVE PRIME LAYERS – THE TROPOSPHERE, THE STRATOSPHERE, THE MESOSPHERE, THE THERMOSPHERE, AND THE EXOSPHERE. ALMOST, AIR PRESSURE AND DENSITY DECREASE THE HIGHER ONE GOES INTO THE ENVIRONMENT AND THE FARTHER ONE IS FROM THE BOTTOM LEVEL.

THE BULK OF THE EARTH’S ENVIRONMENT IS DOWN NEAR THE EARTH ITSELF. IN FACT, 74% OF THE EARTH’S ENVIRONMENT IS AN ACCEPTANCE WITHIN THE FIRST 11 KM ABOVE THE PLANET’S LEVEL. HOWEVER, THE OUTERMOST LAYER (THE EXOSPHERE) IS THE HUGE, DISPERSION FROM THE EXO BASE – STATIONED AT THE TOP OF THE THERMOSPHERE AT AN ELEVATION OF ABOUT 700 KM ABOVE SEA LEVEL – TO ABOUT 10,200 KM (6,200 MI). THE EXOSPHERE CONVERGES WITH THE VOID OF OUTER SPACE, WHERE THERE IS NO ENVIRONMENT.

THE EXOSPHERE IS PRIMARILY COMPOSED OF ENORMOUSLY LOW THICKNESS OF HYDROGEN, HELIUM AND SEVERAL HEAVIER PARTICLES – INCLUDING NITROGEN, OXYGEN AND CARBON DIOXIDE. THE ATOMS AND PARTICLES ARE SO FAR APART THAT THE EXOSPHERE NO LONGER CONDUCTS LIKE A GAS, AND THE MOLECULES INCESSANTLY ELOPEMENT INTO SPACE. THESE MOVING PARTIALS FOLLOW BALLISTIC TRAJECTORIES AND MAY EMIGRATE IN AND OUT OF THE MAGNETOSPHERE OR WITH THE SOLAR AIR.

6. THE EARTH’S MELTED IRON CORE MAKES A MAGNETIC ZONE:

THE EARTH IS LIKE A HUGE MAGNET, WITH POLES AT THE TOP AND BOTTOM NEAR TO THE ACTUAL GEOGRAPHIC POLES. THE MAGNETIC FIELD IT MAKES FILL THOUSANDS OF KILOMETERS OUT FROM THE LEVEL OF THE EARTH – FORMING A ZONE CALLED THE “MAGNETOSPHERE“. SCIENTISTS THINK THAT THIS MAGNETIC ZONE IS PRODUCED BY THE MELTED OUTER CORE OF THE EARTH, WHERE HEAT MAKES CONVECTION MOTIONS OF CONDUCTING PARAPHERNALIA TO GENERATE ELECTRIC CURRENTS.

BE GRATEFUL FOR THE MAGNETOSPHERE. WITHOUT IT, PARTICLES FROM THE SUN’S SOLAR AIR WOULD HURT THE EARTH STRAIGHT, EXPOSING THE LEVEL OF THE EARTH TO VALUABLE AMOUNTS OF RADIATION. INSTEAD, THE MAGNETOSPHERE CHANNELS THE SOLAR WIND AROUND THE PLANET, PROTECTING US FROM HARM. SCIENTISTS HAVE ALSO THEORIZED THAT MARS’ THIN ENVIRONMENT IS DUE TO IT KEEPING A WEAK MAGNETOSPHERE COMPARED TO EARTH’S, WHICH ALLOWED SOLAR WIND TO SLOWLY STRIP IT AWAY.7.

7. EARTH DOES NOT TAKE 24 HOURS TO ROTATE ON ITS AXIS:

IN FACT, IT TAKES 23 HOURS, 56 MINUTES AND 3 SECONDS FOR THE EARTH TO ROTATE ONCE PERFECTLY ON ITS AXIS, WHICH ASTRONOMERS REFER TO AS A SIDEREAL DAY. NOW WAIT FOR A SECOND, DOESN’T THAT MEAN THAT A DAY IS 4 MINUTES LESS THAN WE THINK IT IS? YOU’D THINK THAT THIS TIME WOULD ADD UP, DAY BY DAY, AND WITHIN A FEW MONTHS, THE DAY WOULD BE NIGHT, AND NIGHT WOULD BE THE DAY.

BUT REMEMBER THAT THE EARTH ORBITS AROUND THE SUN. EVERY DAY, THE SUN MOVES COMPARED TO THE BACKGROUND STARS BY ABOUT 1° – AND THE SIZE OF THE MOON IN THE SKY. AND SO, IF YOU ADD UP THAT SMALL MOTION FROM THE SUN THAT WE SEE BECAUSE THE EARTH IS ORBITING AROUND IT, AS WELL AS THE ROTATION ON ITS AXIS, YOU GET A TOTAL OF 24 HOURS.

THIS IS WHAT IS AWARE OF A SOLAR DAY, WHICH CONTRARY TO A SIDEREAL DAY IS THE AMOUNT OF TIME IT TAKES THE SUN TO RETURN TO THE SAME PLACE IN THE SPACE. KNOWING THE DIFFERENCE AMID THE TWO IS TO KNOW THE DIFFERENCE AMID HOW LONG IT TAKES THE STARS TO SHOW UP IN THE SAME PLACE IN THE SKY, AND THEN IT TAKES FOR THE SUN TO RISE AND SET ONCE

8. A YEAR IS NOT COMPLETED IN 365 DAYS:-

IT’S ACTUALLY 365.1/4 DAYS. IT’S THIS EXTRA .1/4 DAYS THAT MAKES THE NEED FOR A LEAP YEAR ONCE EVERY FOUR YEARS. THAT’S WHY WE NAIL ON AN EXTRA DAY IN FEBRUARY EVERY FOUR YEARS – 1996, 1998, 2000, ETC. THE EXCEPTIONS TO THIS RULE ARE IF THE YEAR IN QUESTION IS DIVISIBLE BY 100 (1800, 1900, ETC) UNLESS IT DIVISIBLE BY 400 (1600, 2000, ETC).

9. EARTH HAS 1 MOON AND 2 CO-ORBITAL SATELLITES:

AS YOU’RE PROBABLY KNOWN, EARTH HAS 1 MOON. BUT DID YOU KNOW THERE IS 2 EXTRA STARLET LOCKED INTO CO-ORBITAL ORBITS WITH EARTH? THEY’RE CALLED 3753 CRUITHNE AND 2002 AA29, WHICH ARE PART OF A LARGER POPULATION STARLET KNOWN AS NEAR-EARTH OBJECTS (NEOS).

THE STARLET KNOWN AS 3753 CRUITHNE MEASURES 5 KM ACROSS, AND IS OCCASIONALLY CALLED “SECOND MOON OF EARTH”. IN FACT, IT DOESN’T ORBIT THE EARTH BUT HAS A SYNCHRONIZED ORBIT WITH OUR HOME PLANET. BUT IT HAS ALSO AN ORBIT THAT TEXTURE LOOKS LIKE IT’S FOLLOWING THE EARTH IN ORBIT, IN FACT, IT FOLLOWING ITS OWN, SEPARATE PATH AROUND THE SUN.

2002 AA29 IS ONLY 61 METERS ACROSS AND DESIGN A HORSESHOE ORBIT AROUND THE EARTH THAT INTRODUCES IT CLOSE TO THE PLANET EVERY 95 YEARS.IT WILL APPEAR TO SCANSION EARTH IN A QUASI-SATELLITE ORBIT. SCIENTISTS HAVE SUGGESTED THAT IT MIGHT MAKE A GOOD TARGET FOR A SPACE INVESTIGATION.

10. ONLY PLANET EARTH HAVE LIFE:

WE’VE DISCOVERED PAST DEMONSTRATION OF WATER AND ORGANIC PARTIALS ON MARS, AND THE BUILDING BLOCKS OF LIFE ON SATURN’S MOON TITAN. WE CAN SEE AMINO ACIDS IN NEBULAE IN DEEP SPACE. AND SCIENTISTS HAVE SPECULATED ABOUT THE POSSIBLE EXISTENCE OF LIFE BENEATH THE ICY CRUST OF JUPITER’S MOON EUROPA AND SATURN’S MOON TITAN. BUT THE EARTH IS THE ONLY PLANET LIFE HAS ACTUALLY BEEN SEARCH.

BUT IF THERE IS LIFE ON OTHER PLANETS, SCIENTISTS ARE CONSTRUCTION THE EXPERIMENTS THAT WILL HELP FIND IT. FOR EXAMPLE, NASA JUST DECLARES THE CREATION OF THE NEXUS FOR EXOPLANET SYSTEM SCIENCE (NSS), WHICH WILL LIVE THE COMING YEARS GOING THROUGH THE DATA SENT BACK BY THE KEPLER SPACE TELESCOPE (AND OTHER MISSIONS THAT HAVE YET TO BE START) FOR HINTS OF LIFE ON EXTRA-SOLAR PLANETS.

 

HUGE RADIO DISHES ARE CURRENTLY CHECKED DISTANT STARS, HEARING FOR THE SPECIALTY SIGNALS OF INTELLIGENT LIFE ARRIVE OUT ACROSS INTERSTELLAR SPACE. AND LATEST SPACE TELESCOPES, SUCH AS NASA’S JAMES WEBB TELESCOPE, THE TRANSITING EXOPLANET SURVEY SATELLITE (TESS), AND THE EUROPEAN SPACE INSTITUTIONS DARWIN MISSION MIGHT JUST BE STRONG ENOUGH TO SENSE THE PRESENCE OF LIFE ON OTHER WORLDS.
