Every April 22nd, we celebrate Earth Day, a tradition that started in 1970 to honor the incredible planet we live on. This special day helps us focus on the environmental issues Earth faces and emphasizes the need to safeguard our planet for those who come after us. However, shouldn’t we treat every day as Earth Day? After all, we only have one wonderful planet. We invite you to enjoy these 10 fascinating facts about Earth that we’ve gathered for you.

- The Earth’s atmosphere is divided into several layers, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
- The ozone layer in the Earth’s stratosphere absorbs approximately 97–99% of the Sun’s ultraviolet (UV) radiation, protecting life from harmful effects.
- The Earth’s rotation is gradually slowing down due to tidal forces exerted by the Moon and the Sun, causing the length of a day to increase over geological time scales.
- Earth’s magnetic field is generated by the movement of molten iron and nickel in the outer core, creating a magnetic dynamo effect.
- The Earth’s magnetic poles periodically reverse, with the magnetic north and south poles swapping places over geological time scales.
- Earth’s lithosphere is divided into several tectonic plates that constantly move and interact, leading to earthquakes, volcanic eruptions, and the formation of mountains.
- Earth’s oceans play a crucial role in regulating the planet’s climate by absorbing and redistributing heat, moisture, and carbon dioxide.
- The Earth’s axial tilt is responsible for the changing seasons as different parts of the planet receive varying amounts of sunlight throughout the year.
- Earth’s atmosphere is composed mainly of nitrogen (78%) and oxygen (21%), with traces of other gases such as argon, carbon dioxide, and water vapor.
- The Earth’s magnetic field protects the planet from harmful solar radiation and cosmic rays, deflecting charged particles away from the atmosphere.
- Earth’s climate is influenced by factors such as solar radiation, atmospheric composition, ocean currents, and greenhouse gas concentrations.
- Earth’s oceans cover approximately 71% of the planet’s surface and contain about 97% of its water, with the remaining 3% found in glaciers, ice caps, and freshwater bodies.
- The Earth’s biosphere encompasses all living organisms and their interactions with the environment, including ecosystems, communities, and populations.
