A specific soil profile in a temperate grassland exhibits a deep A-horizon with high organic matter content. If the soil is classified as a Mollisol, which of the following processes most significantly contributes to its high Cation Exchange Capacity (CEC) and fertility?
During an El Niño Southern Oscillation (ENSO) event, which of the following changes in oceanic and atmospheric conditions is typically observed in the eastern Pacific Ocean near the coast of South America?
The Coriolis effect influences the direction of the Prevailing Westerlies in the Southern Hemisphere. As air moves from the subtropical high-pressure zone at \( 30^{\circ}S \) toward the subpolar low-pressure zone at \( 60^{\circ}S \), in which direction is it deflected, and what is its resulting path?
A soil sample is analyzed and found to contain 20% clay, 50% sand, and 30% silt. According to the soil texture triangle, if a farmer adds a significant amount of compost (organic matter) to this field, how will the water-holding capacity and cation exchange capacity (CEC) most likely be affected?
A researcher compares two soil profiles. Soil A is found in a tropical rainforest and Soil B is found in a temperate grassland. Which of the following statements correctly compares the Cation Exchange Capacity (CEC) and the nutrient retention of these two soils?
Describe the Hadley Cell circulation pattern and explain how the adiabatic cooling and heating of air masses lead to the formation of distinct biomes at \(0^{\circ}\) and \(30^{\circ}\) latitudes.

Unit 4: Earth Systems and Resources
The soil profile of a specific region in a tropical rainforest is being analyzed for its agricultural potential.
(a) Identify and describe the characteristics of the O-horizon and the A-horizon in this specific biome.
(b) Explain how high precipitation in tropical regions leads to the process of leaching and how this affects the fertility of the B-horizon.
(c) A farmer decides to clear a section of this rainforest for cattle ranching. Predict the change in the soil's water-holding capacity and explain the reasoning behind your prediction based on soil texture and organic matter content. <\/p>
