Earth, which is also known as the Blue Planet, is the third planet from the sun and the only known planet in the universe that harbors life. It is home to billions of people and millions of species of plants and animals, making it a unique planet in the solar system. Here are some interesting facts about Earth that kids will enjoy learning.
1. Earth is not a perfect sphere
Unlike what most people believe, our planet’s shape is not perfectly round, but rather it is slightly flattened at the poles and bulges at the equator. This shape is known as an oblate spheroid.
2. Earth’s atmosphere is made up of different gases
The air we breathe is composed of nitrogen (78%), oxygen (21%), and other gases (1%) such as argon, carbon dioxide, and neon. The atmosphere also protects Earth from harmful radiation and provides the necessary environment for life to thrive.
3. Earth is the only planet with liquid water
Water covers 71% of Earth’s surface, making it the only planet in the solar system with liquid water. Water is a crucial resource for life, and it is essential for various processes such as photosynthesis, digestion, and hydration.
4. Earth has an invisible shield called the magnetic field
Earth’s magnetic field acts as a force field around the planet that protects it from harmful solar winds and radiation. The magnetic field is created by Earth’s iron core and extends into space, providing a protective shield.
5. Earth’s rotation causes day and night
The Earth rotates on an imaginary axis, and it takes 24 hours to complete one rotation. This rotation causes day and night, with the sun shining on one side of Earth while the other side is in darkness.
6. Earth travels at a rapid speed through space
While it may not feel like it, our planet is moving incredibly fast through space. Earth orbits the sun at a speed of approximately 107,000 km/h, taking one year to complete one orbit.
7. Earth has the right conditions for life
temperature, atmospheric pressure, and chemical composition of Earth are just right to support life. The planet’s distance from the sun, the presence of liquid water, and the protective atmosphere are all factors that make Earth an ideal place for life to exist.
