5 Questions
What are some important chemicals found in seawater that are needed to sustain life?
Nitrogen (N2), oxygen (O2), and carbon dioxide (CO2)
How can nitrogen-containing fertilizer runoff impact ocean plants and creatures?
It can cause ocean plants to grow excessively, using up more dissolved oxygen and suffocating other ocean creatures like crabs and fish.
What role do oceans play in the study of global climate changes?
Oceans act as carbon sinks, absorbing and storing carbon dioxide from the atmosphere, thus helping to reduce greenhouse gases.
What is the relationship between ocean water temperature and the sun's energy?
Ocean water has a high heat capacity, meaning it takes a long time for the sun's energy to heat the water and for the water to release that heat.
How does the salinity of ocean water affect its freezing point?
As the amount of salt in water increases, the freezing point decreases, which is why ocean water freezes at a lower temperature than freshwater.
Test your knowledge about the unique properties of ocean water, including its salinity, freezing point, and layered composition. Discover fascinating facts and gain a deeper understanding of the mysteries of the sea.
