1. Earth's Age:
he planet is approximately 4.54 billion years old, based on radiometric age dating of meteorite material.
2.Blue Marble:
About 71% of Earth's surface is covered by water, making it unique among the planets in our solar system.
3. Atmosphere:
Earth's atmosphere is primarily composed of nitrogen (78%) and oxygen (21%), with trace amounts of other gases.
4. Magnetic Field:
Earth has a powerful magnetic field created by its molten iron core, protecting us from harmful solar winds.
5. Axial Tilt:
The planet's axis is tilted at about 23.5 degrees, causing seasonal changes as Earth orbits the Sun.
6. Tectonic Plates:
Earth is the only known planet with active tectonic plates, which play a crucial role in the carbon cycle and shaping landscapes.
7. Unique Moon:
Our Moon is unusually large compared to other moons in the solar system relative to its planet’s size, stabilizing Earth's axial tilt.
8. Extreme Temperatures:
The hottest temperature recorded on Earth is 56.7°C (134°F) in Death Valley, USA, and the coldest is −89.2°C (−128.6°F) in Antarctica.
9. Oxygen from Oceans:
Over half of Earth's oxygen comes from phytoplankton in the oceans, not just trees and plants on land.
10. Biosphere:
Earth is the only planet known to support life, with millions of species coexisting across diverse ecosystems.
