How Do Volcanoes Make New Land Above Sea Level?

火山如何在海平面以上制造新陆地?

  1. Undersea volcanoes erupt hot lava that cools in seawater.
  2. Hardened lava builds up over many eruptions until it reaches the surface.
  3. Hawaii’s islands formed this way over millions of years.
  4. Lava flows add layers and widen the land gradually.
  5. Wind, rain, and plants later turn bare rock into soil.
  6. New land appears slowly — sometimes just centimeters per year.
  7. Scientists watch active undersea volcanoes to predict future islands.
  8. This natural process shows how Earth’s surface keeps changing.
