Question

study questions

1. where are mineral resources usually found, and what geological processes contribute to their distribution?
2. describe the formation process of fossil fuels like coal, oil, and natural gas.
3. compare soil fertility in valleys and on hillsides, and explain the reasons for any differences.

Explanation:

Answer:

1. Mineral resources are found in the Earth's crust, often concentrated in ore deposits; their distribution is determined by geological processes such as magmatic activity, hydrothermal circulation, sedimentation, and plate tectonics.
2. Fossil fuels form from the remains of ancient organisms that were buried under layers of sediment and subjected to intense heat and pressure over millions of years, undergoing anaerobic decomposition and chemical transformation.
3. Valleys generally have higher soil fertility than hillsides because gravity and water transport nutrients and fine sediments (alluvium) downhill, where they accumulate, whereas hillsides experience higher rates of erosion and leaching.
