What About Climate Change And The Global Water Cycle? - The Water Cycle

The video discusses how ocean salinity is influenced by evaporation and rainfall, with evaporation leaving salt behind and rainfall diluting it. It highlights the importance of measuring ocean salinity to understand the global water cycle. Technological advancements, such as automatic buoys and robotic floats, have improved salinity measurements. Data from these tools and other sources reveal changing salinity patterns, possibly linked to global warming.

What happens to the salt when water evaporates from the ocean surface?

• It turns into freshwater.

• It forms clouds.

• It remains in the ocean.

• It evaporates with the water.

How does heavy rainfall affect ocean salinity?

• It has no effect on salinity.

• It increases salinity.

• It dilutes the salt, making the water fresher.

• It causes more evaporation.

What is one of the tools used to understand the global water cycle?

• Wind patterns

• Ocean salinity

• Tidal waves

• Ocean currents

What technology is used to measure ocean salinity?

• Submarines

• Satellites

• Weather balloons

• Automatic buoys and robotic floats

What do the emerging patterns in salinity changes indicate?

• The water cycle may be changing due to global warming.

• The water cycle is stable.

• The water cycle is becoming more predictable.

• There is no change in the water cycle.
