2.4. Role of Oceans in the Water Budget

Try these first

1. 1.

   What percentage of global evaporation do oceans contribute?

   Hint

   Remember the high percent associated with oceans.

2. 2.

   What percentage of water on Earth is stored in oceans?

   Hint

   Think about the vastness of oceans compared to other water bodies.

3. 3.

   What percentage of global evaporation comes from the oceans?

   • 86%
   • 78%
   • 96%

   Hint

   Think about the relationship between oceans and evaporation.

4. 4.

   Oceans account for what percentage of Earth's total water?

   • 78%
   • 96.5%
   • 86%

   Hint

   Consider how much of Earth is covered by water.

5. 5.

   Consider a scenario where ocean temperatures increase due to climate change. Describe the potential effects on global precipitation patterns and local weather conditions.

   Hint

   Think about how temperature changes relate to evaporation rates.

6. 6.

   Evaluate the significance of ocean water composition for both marine life and human usage, considering the percentage of salt in ocean water.

   Hint

   Focus on the difference between saltwater and freshwater sources.
