67 Interesting Facts About Earth – Our Mother Planet

Last updated on November 26th, 2017

Craters, seasons, layers, oceans, rings

#41. Earth does not have many craters (less than 200) on the surface as do the other planets have.

#42. The seasons on Earth are due to its tilt against the Sun. Earth’s axis of rotation is tilted 23.4 degrees with respect to its plane of rotation around the Sun.

#43. Earth is composed of four main layers – inner core, outer core, mantle, and crust.

#44. Earth is exactly at a distance of 1 AU from the Sun. AU (the distance from the Sun to Earth) is the standard unit of measurement of the distance of celestial bodies from the Sun. And Earth’s measurements are used as a standard.

#45. Earth is the fifth largest planet in terms of size and mass.

#46. Earth has an Ozone layer which protects it from Sun’s powerful and harmful UV rays.

#47. Light from the Sun reaches the Earth in approximately 8 minutes and 20 seconds.

#48. Almost 70% of the earth’s surface is covered by oceans that contain 97% of the planet’s water. These oceans are home to great mysteries and tons of geographical features that are not even available on the land. E.g. Earth’s longest mountain range is also underwater.

#49. It is estimated that life initiated in the oceans some 3.8 billion years ago. 

#50. Earth has no rings. However, Jupiter has 4 set of rings and Saturn has 4 main group of rings and 3 fainter group of rings.

#51. Did you know that a magnetic field reversal takes place every 40,000 years on average? At the time of this reversal, the magnetic polarity of the earth will change that will bring a change in the direction of Earth’s magnetic field.

Highest and deepest points

#52. The highest point: The peak of Ecuador’s Mount Chimborazo, located just one degree south of the Equator is the highest point on Earth. At this point, the Earth’s bulge is greatest.

#53. The deepest known place: “Challenger deep” – near a trench called the “Mariana Trench” beneath the surface of the Pacific Ocean to the southeast of Japan — is the deepest known place on Earth. This trench is nearly seven miles deep.

Hottest and coldest locations

#54. The highest recorded temperature: it is 56.7°C (134°F), measured on 10 July 1913 at Greenland Ranch, Death Valley, California, USA.

#55. The coldest permanently inhabited place: Oymyakon, a village in Siberia, Russia, is where the temperature reached -68 degree Celsius. And the coldest temperature ever recorded on Earth was at Antarctica’s Vostok station – minus 89.2 degree Celsius.

Flattest, wettest and driest places

#56. Wettest place: Mawsynram in Meghalaya, India is the wettest place on land on Earth. It receives an average annual rainfall of 11,871 mm. This place is just 10 miles away from the town of Cherrapunji (another record holder for the wettest month and year ever recorded.)

#57. Driest place: Dry Valleys in Antarctica is the driest place on Earth. This place has seen no rainfall for the past 2 million years. This is a 4800 square kilometer region with no ice, snow or water.

#58. Flattest country: Maldives is the flattest country in the world with an average highest above sea level of 2.4m.

#59. The Nile is the longest river on Earth that extends 6,695 km from its source in Burundi to the Mediterranean sea. However, Amazon is the biggest river in the world in terms of the water that flows down it.

#60. Unknown minerals: scientists have recently calculated that there are more than 1500 minerals that are still undiscovered in the Earth. We are aware of more than 5000 minerals but many are still unknown. Another captivating fact here is that the Earth’s mineral diversity is unique to itself and is not duplicated on any other planet, not even the rocky exoplanets.

#61. Carbon-di-oxide spitting lakes: there are three crater lakes – Nyos, Monoun, and Kivu, that sit in Cameroon and on the border of Rwanda and the Democratic Republic of Congo. These lakes spit carbon dioxide at an enormous level and have been the cause of deaths of hundreds of people in the past. This phenomenon happens because of the presence of magma below the surface of the lakes and this magma releases carbon dioxide into the water which causes the resulting spewing of the gas into the atmosphere.

#62. Rocks that move by themselves: Some rocks on our planet Earth move by themselves. However, scientists have failed to capture the actual motion of these rocks because they move so little but their movement is certain.

#63. Out of Earth: The boundary between Earth’s atmosphere and outer space is known as the Karman Line. This boundary lies at a distance of 100 km from Earth’s sea level. Anyone who goes beyond this line is considered an astronaut.

#64. The Earth and the Sun: The minimum distance between the earth and the Sun (perihelion) is 147.1 million kilometers and the maximum distance (aphelion) between the earth and the Sun is 152.1 million kilometers.

#65. There is a possibility that some asteroid/comet may hit earth and cause devastation to life. A similar event 65 million years ago happened and wiped out the dinosaurs from the planet.

#66. Since record keeping for temperature began in 1880, 2016 was recorded as the hottest year ever. The temperature recorded in 2016 was 1.69 degrees Fahrenheit above the 20th-century average.

#67. Scientists have recently estimated that an ocean of water exists at a distance of 1,000 km under the surface of the Earth. And this water is important for volcanic activity, which in turn is responsible for generating soil.
