Quick fun factπŸ€“

If you started making a soil layer today and waited for it to grow just 30cm deep, you might have to wait up to 10,000 years! So next time you’re feeling impatient, remember soil’s got you beat.

What exactly is soil πŸ€”

  • Outermost layer of Earth's surface.
  • Mix of:
    • Weathered bedrock (called regolith) πŸͺ¨
    • Organic matter (dead and alive stuff) πŸ‚πŸœ
    • Air 🌬️
    • Water πŸ’§

The speed of soil formation 🐒 vs πŸ‡

  • 30 cm soil layer = 1,000 to 10,000 years to form.
  • Soil forms sooo slowly, it's like that movie you watched which felt like it was never-ending. πŸΏπŸ“½οΈ
  • Because of its sloth-like speed, it’s a non-renewable resource.
