Question

1. ocean temperature is usually __________ at the surface and __________ in the deep ocean.
2. the ____________ provides energy that heats the oceans, especially near the equator.
3. warm water is __________ than cold water, so it tends to __________
4. the movement of ocean water driven by temperature and salinity differences is called ____________
5. oceans near the poles are __________ than oceans near the tropics because they receive less __________
6. warm and cold currents can influence the ____________ of nearby coastal regions.
7. if global ocean temperatures continue to ____________ ocean currents and climate patterns may change.
8. many marine species are found only in certain ____________ ranges because temperature affects their survival.
9. warm ocean water provides energy for ____________ making them stronger and more destructive.

Explanation:

1. Sun - heats the surface. Cooler in deep due to lack of sunlight.
2. Sun is main heat source for oceans.
3. Less dense, floats. Warm water has lower density than cold water.
4. Thermohaline circulation - driven by temp and salinity.
5. Colder, sunlight. Poles receive less direct sunlight.
6. Climate. Ocean currents affect coastal climate.
7. Rise. Rising temps can disrupt currents and climate.
8. Temperature. Marine species have specific temp needs.
9. Hurricanes. Warm water fuels hurricane formation and intensification.
