The Earth's atmosphere within 10 km of the surface contains approximately 78% nitrogen, 21% oxygen, and the remaining 1% is made up of trace gases such as argon, carbon dioxide, neon, helium, and methane.
Approximately 0.005% of Earth's water can be found in the soil. This water is critical for plant growth and ecosystem functioning, as well as for supporting life above and below the ground.
Approximately 11% of the Earth's surface is suitable for growing crops. This usable land is primarily found in regions with favorable climates, soil conditions, and access to water for irrigation.
Approximately 97% of Earth's water is found in the oceans, while the remaining 3% is found in glaciers, groundwater, lakes, rivers, and in the atmosphere.
Approximately 20% of the Earth's land surface is covered by savanna, making it one of the largest biomes in the world. Savannas are characterized by a mix of grasses and scattered trees, and they are found in tropical and subtropical regions across the globe. They play a crucial role in supporting a diverse range of plant and animal species.
