How do i know where the arrows should point?
Why is the Atlantic Ocean the saltiest ocean on Earth? In your explanation, use the terms “evaporation,” “precipitation,” “trade winds,” “Central America,” and “Pacific Ocean”.?
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 below

- The 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_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.

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.
