Dynamic Core: Earth’s core is as hot as the surface of the sun, with temperatures reaching up to 5,400°C (9,800°F). It generates the planet’s magnetic field, which protects us from harmful solar radiation.
The Blue Planet: Over 70% of Earth’s surface is covered by water, which is why it's often called the "Blue Planet." Despite this abundance, only about 2.5% of it is freshwater, with the rest being salty ocean water.
Earth’s Age: Earth is estimated to be about 4.54 billion years old, based on dating of the oldest rocks and meteorites.
Moon’s Role: The Moon is slowly drifting away from Earth at a rate of about 3.8 centimeters (1.5 inches) per year. This is gradually slowing down Earth’s rotation, lengthening our days.
Earth’s Atmosphere: Our atmosphere is composed of 78% nitrogen, 21% oxygen, and 1% other gases. It’s essential for life, providing oxygen to breathe and shielding us from harmful UV radiation.
Ever-Changing Surface: Earth's surface is constantly changing due to tectonic activity, erosion, and human influence. Over millions of years, entire continents have shifted and reformed.
Gravitational Anomalies: Earth's gravity isn’t uniform. The planet has variations in gravitational pull, caused by factors like mountains, ocean trenches, and differences in Earth’s density.
