The changes that happen when water turns to ice might be the key to creating volcanoes that erupt liquid water in the outer solar system.
Temperature within these objects goes up as you head deeper and as pressure increases, the melting point of water decreases. Add in any salts that might be part of this ice to further drop the melting point, and you have a pretty good chance of pockets of liquid water in the ice layers or even deep oceans of liquid underneath the icy shells.In many ways, on these icy moons, water and ice behave a lot like magma and rock do on Earth.
The same can't be said for most icy worlds. What do ice cubes and icebergs do? They float! That's because ice is less dense than liquid water , so by that logic, liquid waterIn preparation for Europa Clipper, NASA scientists recently reprocessed old Galileo spacecraft data from the 1990s with modern techniques to get new, more detailed views of so-called "chaos terrain" on the moon's surface.

From Droughts to Floods, Water Risk Is an Urgent Business IssueAs climate change advances, floods and droughts are now sudden, unforeseen events that increasingly hit areas in quick succession, and this growing variability has caught major corporations unprepared. New regulation is forcing companies to confront this growing risk. Companies need to understand their vulnerabilities and plan how to address them. They should start by assessing their water quantity impacts and setting water use reduction targets that are informed by local conditions. Second, they should assess their water quality impacts and use this assessment to set targets and develop action plans to improve that impact, such as reducing the use of harmful chemicals, investing in recycling technology, and reducing pollutant discharges. Third, companies should engage deeply in water stewardship activities in the basins in which they operate by advocating for watershed protection, or by supporting new water conservation and groundwater sustainability policies. Finally, companies should ensure that water-related risks and opportunities are fully embedded within corporate governance and decision making.
