Interesting Facts About Earth you Would Love to Explore

Apparently, Earth is the only planet that supports life. Earth, along with many other planets was formed after very sorted and long processes that followed the nebula explosion. As per the nebular hypothesis, all bodies of the solar system were formed after nebula explosion.  The sun and the planets were huge balls of gases and dust, which gradually settled down under the effect of rotational and gravitational forces.

The continents we see today, were not in the same shape over billions of years ago. The gigantic plates, which once formed a super continent, were separated that took millions of years to change. They then gradually joined back to form separate continents that we know today. Earth is dynamic and over billions of years, it has changed a lot and will always be changing. You will be furthermore amazed to know that there were times when earth didn’t even support life. This was the proto-earth stage of earth. Proto-earth was larger than the earth size today; there was no oceans and no life. The atmosphere of the earth had a homogenous composition and was continuously bombarded by meteorites. The environment was dusty and full of gases.

Fortunately, in a few millions years further, things on earth got much better and things settled.  Many parameters that support life gradually started building up and helped in the formation of life, earth became somewhere bit closer to what it is in present scenario.

From our perspective, the Earth appears as big and sturdy place with an endless ocean of air. From the space, astronauts see it as a small planet with thin fragile layers of atmosphere. Earth is a ball of blue ocean waters, brown and green landmasses and white clouds. The Earth is like a space ship for those who are residing here, which is traveling at a speed of 108,000 kilometers an hour.  Earth is the third farthest planet from the sun at a distance of about 150 million kilometers away from Sun. There are 365 days in a year.  Do you know why? This is so because earth takes about 365.256 days to complete its revolution around the sun. Again, do you know why a day has 24 hours? Well, because earth takes 23.9345 hours to rotate on its axis. There are many such very interesting facts about the planet earth, may be you know few or maybe you do not. These jaw-dropping and amazing facts are majorly based on the geographical aspects of the earth.

Every day something interesting and amazing is deciphered on this planet. Indeed, most our oceans haven’t yet been explored which is why new depths are yet to be known.These oceans come up with hundreds of new species. Similarly, as often we explore rainforests we get to encounter new animals and plants.  Earth is so vast and it keeps surprising humans with its various secrets. It took many years for humans to know about the atmosphere and the existence of the Earth and the universe. Here are some of the most amazing facts about the planet earth.

Let us have a look on few of such very interesting facts about earth:

Age Of the Earth:

As per the evidences from the dating of the meteorite, material earth is 4.54 ± 0.05 billion years. This age is also consistent with the ages of the oldest known terrestrial and the lunar samples.

Earth Was Purple:

As earth is green today, but many years down the line it was purple. The ancient microbes might have used a molecule other than chlorophyll to utilize and harness the sun rays, which gave the organisms a violet hue.

As per the studies, it is believed that chlorophyll came into existence after another light-sensitive molecule called retinal. Retinal is found today in the plum-colored membrane these days. This gives red color to the plum.

Actually purple color appears due to the presence of photosynthetic microbe called halo bacteria. This microbe absorbs green light and reflects back red and violet light, the combination of which appears purple. This can be explained more with the idea that sun transmits most of its energy in the green part of the visible spectrum; chlorophyll absorbs mainly blue and red wavelengths.

The Atmosphere

Is Earth Spherical?

Earth is not a perfect Sphere. While it spins on its axis the gravity points towards the center of earth and centrifugal forces pushes outward.However, due to the forces opposing gravity which act perpendicular to the axis of Earth, and Earth’s axis is tilted, centrifugal force at the equator is not exactly opposed to gravity. This causes an imbalance, which adds at equator. Here the gravity pushes extra mass of water and earth into a bulge around our planet. Shape of the Earth is an approximate oblate spheroid, a sphere flattened along the axis from pole to pole.


Amazing Fact of Gravity

The distribution of gravity is completely uneven on the earth. This is related to the fact that globe in not a perfect sphere. Its mass is distributed unevenly. An uneven mass refers to slightly uneven gravity.

One mysterious gravitational anomaly is in the Hudson Bay of Canada .This area has lower gravity than other regions. It was found that the melted glaciers change the mass of the area.

During the ice age, the area was cloaked by ice which has melted now. However, there is still some ice on the planet. Gravity is proportional to the mass atop that region, if the glaciers are pushed aside from the Earth’s mass then the gravity would be little less than earlier.

The slight deformation of the Earth’s crust show an unusual drop of about 25-45 % drop in the gravitational forces. The downward drag that caused motion of magma may explain the rest.

The Electrical Forces

Earth’s fiercer side is revealed by thunder and lightning. A stroke of lightning can heat the air up to 54,000 degrees Fahrenheit, which can expand the air. That ballooning of air creates a shock wave and ultimately a boom called thunder.

Deepest Spot

There are the highest points on earth and there are deepest points too. The deepest point on the ocean floor is 35,813 feet below sea level in the Mariana Trench.  Another interesting fact is that there is one other lowest point after this one, which is not covered by ocean and is 8,382 feet (2,555) meters below sea level. It is in the Bentley Sub glacial Trench in Antarctica, buried under lots and lots of ice.

Earth’s Waistline

Mother Earth has a huge waistline, at the equator. The circumference of the globe is 24,901 miles.

Do Lakes Explode

To astonishment, have you ever heard that lakes explode? Yes, some do, in Cameroon and on the border of Rwanda and the Democratic Republic of the Congo there are three such deadly lakes: Nyos, Monoun and Kivu.

These are the crater lakes and sit above volcanic earth. This is due to the magma, which releases carbon dioxide from below the surface of earth into the lakes, resulting in a deep, carbon dioxide-rich layer right above the lakebed. That carbon dioxide can be released in an explosion for a breathless experience.

Water Getting Over

Due to the climatic changes, earth is facing a water loss. Glaciers are retreating and contributing rise in the sea level.The Canadian Arctic is contributing to the 10 percent of the world’s melt-water. It has lost a volume of equivalent to whopping 75 percent of Lake Erie within 5 years (2004-2009)

The Shifting Plates

The internal processes of the earth make it move swiftly. The shifting slabs of rocks known as tectonic plates though are unseen to us; the after effect of their move is very much visible. Take an example of monumental Himalayas, which stretch 1,800 miles along the border between India and Tibet. This vast mountain range began to form between 40 million and 50 million years ago, when India and Eurasia where driven by plate movement and collided. The tectonic crash led to the jagged Himalayan peaks

The Auroras

When charged particles from the sun is funneled toward Earth by the planet’s magnetic field and collide with the upper atmosphere near the poles then the Aurora occur in the Atmosphere.This phenomenon is more active when the sun’s activity peaks during its 11-year solar weather cycle.

The Super-Colossal Eruption

This was the largest volcanic eruption recorded in the history by humans, in April 1815, the peak of the explosion of Mount Tambora. The eruption ranked 7 on the Volcanic Explosivity Index (VEI), which goes from 1 to 8 and is somewhat alike to the magnitude scale for earthquakes. The explosion was so loud that it was heard Sumatra Island, more than 1,930 km away. The death toll from the eruption was estimated at 71,000 people. The clouds of heavy ash descended on many islands far away.

Mystery Moon

Researchers believed that many years back some large object crashed into the earth, the resulting debris amalgamated to form moon. It is still unclear that the colliding object was a planet, comet or an asteroid. That celestial body was given a hypothetical name, Theia.

Low Lands

The lowest point existing in the world,relatively accessible, is the Dead Sea between Jordan, Israel and the west Bank. The surface is super salty and is 1,388 feet below the sea level.

As vast as earth is vaster are the interesting facts about earth. The interesting facts about the earth are never ending and each day could be the day of new findings about Earth. Scientists are continuously in a zest to know something more interesting that can be known about earth.
