Why Is the Atacama Desert the Driest Place on Earth?

💡 The Answer

• The Atacama Desert lies between the Andes Mountains and the Pacific Ocean, creating a rain shadow effect that blocks moisture.
• The cold Humboldt Current cools the air, preventing evaporation and cloud formation that could bring rain.
• Some parts of the Atacama have never recorded rainfall, making it the driest non-polar desert on Earth.
• Its extreme dryness preserves ancient geoglyphs and provides ideal conditions for astronomical observatories.
