1. The irregular movement of water that deviates from the general circulation pattern and forms loops is called an eddy. Eddies can transport heat, salt, and nutrients across different regions of the ocean.

2. The main cause of oceanic currents is the wind blowing over the surface of the ocean. The friction between the wind and the ocean surface creates a transfer of momentum, leading to the movement of water and the formation of currents.

3. Oceanic currents have a significant effect on climate. They can make coastal regions warmer or colder than inland regions by transporting warm or cold water. They can also increase or decrease precipitation in certain areas by influencing the distribution of moisture. Therefore, the correct answer is d. All of the above.

4. The large circular systems of oceanic currents driven by trade winds and convectional force are called gyres. These gyres circulate water around the major ocean basins.

5. The movement of the air mass causes the temperature and moisture to modify in a warm or cold air mass. As air masses move, they interact with different regions, leading to changes in temperature and moisture content.

6. Hot air can hold more moisture than cold air. Therefore, the correct answer is b. more moisture than cold air.

7. After the passage of a cold front, the surface visibility in a transition zone may become poor. Cold fronts often bring in cooler, denser air, which can lead to the formation of clouds and reduced visibility.

8. After a cold front passes, the barometric pressure reading drops, and the temperature drops. Cold fronts generally bring in cooler air, which leads to a decrease in both pressure and temperature.

9. A series of brief showers accompanied by strong, shifting winds that may occur along or some distance ahead is typically associated with a cold front. Cold fronts often bring in rapidly changing weather conditions.

10. The line of clouds, sharp changes in wind direction, and squalls are typically associated with a cold front. Cold fronts often bring in these weather characteristics as the colder air mass displaces the warmer air mass.

11. As the temperature for a given mass of air increases, the air can hold more moisture. Therefore, the correct answer is b. more moisture than cold air.

12. While on board a moving vessel, wind direction cannot be accurately measured. The movement of the vessel can create turbulence and affect the accuracy of wind direction measurements.

13. The boundary between two air masses is called a front. Fronts are characterized by the contrast in temperature, humidity, and air density between the two adjacent air masses.

14. The formation of a depression in the atmosphere when air rises is called vertical. When air rises, it creates an area of low pressure, leading to the formation of a depression.

15. The ocean current that flows along the east coast of North America and brings warm water to Europe is called the Gulf Stream.

16. The term for the circular movement of water in each major ocean basin is a gyre. Gyres circulate water around the major ocean basins and play a crucial role in global oceanic circulation.

17. Ocean currents have multiple effects on climate. They distribute heat around the world, influencing global temperature patterns. They also influence precipitation patterns by transporting moisture. Additionally, ocean currents can affect wind and storm systems, leading to changes in weather patterns. Therefore, the correct answer is d. All of the above.
