The ways by which the motion shifted from the atmosphere to the ocean surface.
Answer to Problem 1BYL
Pictorial representation: Fig. 1 depicts the transfer of atmosphere motion to the ocean surface.
Fig.1. Atmosphere motion transfer to the ocean surface.
Explanation of Solution
The motion from the atmosphere transferred to the ocean surface as follows:
(i) As the wind blows around the water, it pushes against the surface, which causes the upper layer of the water to flow.
(ii) The surface water transfers some momentum to the water just below the surface.
(iii) The current velocity decreases with depth due to the effect of wind stress, The current velocity becomes zero at a depth of 100m, and this point is known as a null point.
(iv) The water flow parallel to the direction of the blowing wind. The water move due to the Coriolis force.
(v) The effect of the shearing force decreases downward toward the null point. Due to this, the direction of the flow turns farther into right.

- At the large scale of the major ocean basins, do ocean currents tend to flow in a cyclonic or anti-cyclonic direction? How is this evidenced in the map of average sea-surface temperatures belowarrow_forwardThe map below shows sea-surface temperature (SST) anomalies during El Niño years. Please explain what is meant by “anomaly”. In El Niño years, which side (east or west) of the tropical Pacific Ocean experiences anomalously high precipitation totals and which side experiences anomalously low precipitation totals? Why?arrow_forwardWhen 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_forward
- As 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_forwardThe image shows the two different crusts on earth.

Philosophy and Fundamental concepts In this chapter, we discussed the five fundamental concepts of environmental geology: human population growth, sustainability, systems and change, hazardous Earth processes, and scientific knowledge and values. One interesting analogy for Earth is the Gaia hypothesis, which proposes that living organisms interact with their inorganic surroundings to form a synergistic, self-regulating system that helps maintain and sustain conditions for life on the planet. Now my question is Do you think the Earth is a living organism? Why or why not? I understand that many students use generative AI to assist with homework. While AI is undoubtedly a valuable tool for providing information, I believe that human judgment and analytical skills surpass what AI can achieve. My hope is that these assignments will help develop and strengthen your critical thinking skills. Here are answers from Chatgpt: "Do you think the Earth is a…arrow_forward
