We live on our home planet called
Earth, which is one among the 8 planets that revolve around the Sun. According
to the Astronauts photography, it looks like a ball painted with a blue, green
& white. This article explains all the kid facts about Earth
you shouldn’t miss.
It is very important to teach your kid facts about Earth because
we live on the planet Earth. Earth is the 3rd planet from the sun
and largest of the terrestrial. Earth is the fifth largest planet in terms of
size and mass, it is densest (5,513 kg/m of all the planets. It is a planet
which is not named by after mythological being, its name is derived from the
old English word “ertha” and the Anglo-Saxon word “erda” which means soil or
ground.
The Universe is an infinite space,
there are over millions of galaxies in the universe and the Galaxy is a system
which consists of gas, dust, and stars that are held together by the force of
gravity.
The Solar system consists of total 8
planets and a Sun. Where the sun is in the center of the solar system and other
8 planets revolves around it. These 8 planets revolve within their particular
orbits without colliding with each other. In the order of distance from the sun
here are the eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn,
Uranus, and Neptune. Pluto was the ninth planet of our solar system until the International
Astronomical Union (IAU) passed two resolutions that revoked Pluto’s
planetary status.
Important kid facts about earth
The
rotation of the Earth is slowing down:
The rotation of the earth has been gradually decreased,
approximately 17 milliseconds per 100 years. This eventually will lengthen our
days. But it takes around 140 million years before our day will have increased
from 24 to 25 hours.
Powerful magnetic field:
Earth has powerful magnetic field
which protects from the effects of solar winds and it is believed to be a
result of the nickel-iron core of the planet combined with its rapid rotation.
The Earth has an
Ozone Layer:
Earth has Ozone layer which protects from harmful solar radiations. This Ozone layer shell is a special type of oxygen that absorbs most of the Sun’s powerful UV rays.
Most of the
Earth’s surface is covered by water:
70% of the earth’s surface is covered by the water, the remainder consists of continents and islands which together have many lakes and other sources of water.
Atmosphere:
The atmosphere of the earth consists
of several layers of gases which is generally called as air, that surrounds the
planet Earth and retained by Earth’s gravity.
Earth’s atmosphere is the thickest
within the first 50km from the surface or so, but it reaches out to 10,000 km
into space. Earth is made up of five layers, they are Stratosphere,
Troposphere, Mesosphere, Thermosphere, and the Exosphere.
Oceans of Earth:
Orbital
Characteristics:
The earth consists of several orbital
characteristics but to named few they are as follows:
Aphelion,
Perihelion, Eccentricity and orbital period.
Characteristics- The total distance is
152100000 km whereas, Perihelion is 147095000 km and
Eccentricity is 0.0167086.
The Orbital period is often calculated
either in terms of days and years. It is exactly 365.256363004 days which sums as 1.00001742096 year
No of continents
on Earth: There are total 7 continents on the
earth and entire world is divided in those 7 continents. The temperature and
biosphere is different for all the continents. The Seven continents of Earth
are as follows:
- North America
- South America
- Antarctica
- Europe
