To describe: The movement of a raft at rest that is beyond the surf zone and in the surf zone.
![Check Mark](/static/check-mark.png)
Answer to Problem 1GST
When the raft rests beyond the surf zone, it is affected by the circular orbital motion with more up and down motion than the forward motion. However, if it is at rest in the active surf zone where water proceeds to the shore, the raft will experience a forward motion than the up–down movement, and it moves close to the shore.
Explanation of Solution
Ocean waves represent the energy waves that are travelling along the interface between the ocean and atmosphere. Wind is the major driving force for the waves to travel several thousands of kilometers.
As a wave passes, water moves in a circle to transfer the energy. This circular motion is termed as circular orbital motion. Such a motion permits the forward movement of the wave through water during which the movement of the individual water particles transmitting the wave is in a circle.
An object resting beyond the surf zone will be affected by the circular orbital motion, and it advances with a more up and down motion and a less forward motion. However, if the object is still in the surf zone where the waves act turbulently moving the water toward the shore, the lateral or forward motion is more when compared to the up–down motion and the object; here, the raft moves toward the shore.

In your explanation, use the terms “evaporation,” “precipitation,” “trade winds,” “Central America,” and “Pacific Ocean”.?arrow_forwardAt the large scale of the major ocean basins, do ocean currents tend to flow in a cyclonic or anti-cyclonic direction?

- When a body of cold air near earth’s surface moves into a region occupied by warmer air, the point of intersection is known as a cold front. What does this do to the vertical motion of the warm air and why? What does this do to surface pressure ahead of the cold front and why ?Does this tend to instigate cyclonic or anti-cyclonic atmospheric rotation ? Does this rotation tend to bring relatively warm air toward the poles or toward the lower latitudesarrow_forwardAs the atmosphere and ocean move, they are deflected due to the spin of the earth. Is the deflection to the right or to the left in the Northern Hemisphere? Is this the same in the Southern Hemisphere ? In both hemispheres, a low pressure will instigate cyclonic flow. In the Northern Hemisphere, does cyclonic flow circulate in a clockwise or counter-clockwise direction and whyarrow_forwardIs the seasonal cycle in temperature (temperature difference between warmest and coolest season) stronger in the tropics or high latitudes, and why ?How about in “maritime” areas that are regularly exposed to air that was recently over the ocean versus more continental areas, and why?arrow_forward
