Problem: What does the discovery of water under the Earth's crust mean for understanding the planet's geology and water cycle? How does this water compare to other sources of water on Earth, such as oceans, lakes, and rivers? What are some of the potential benefits and drawbacks of this discovery? Should we continue to search for water on other planets, such as Mars? Why or why not? Could humans ever live on Mars, given the current understanding of the planet's water and atmospheric conditions? How might the discovery of water under the Earth's crust impact our efforts to address global water scarcity and climate change? What are some of the potential applications of this discovery in fields such as agriculture, industry, and energy production? With references. Need Assignment Help?
