The correct answer is Process of Soil formation.

Key Points

  • Pedogenesis is the scientific term for the process of soil formation.
  • This process involves the breakdown of parent material (such as rock) through various physical, chemical, and biological processes.
  • Factors influencing pedogenesis include climate, organisms, topography, parent material, and time.
  • The end result of pedogenesis is the formation of soil horizons, which are distinct layers within the soil that have different characteristics.
  • Soil formation is crucial for agriculture, ecosystems, and plant growth as it provides essential nutrients and a medium for roots to anchor.

 Additional Information

  • Study of Volcanic eruption
    • The study of volcanic eruptions falls under the field of volcanology.
    • Volcanologists study the formation, activity, and effects of volcanoes.
    • This field involves understanding the eruption mechanisms, predicting eruptions, and mitigating volcanic hazards.
  • Process of Lava formation
    • The process of lava formation is part of igneous petrology.
    • Lava is the molten rock that emerges from a volcano during an eruption.
    • When lava cools and solidifies, it forms igneous rocks.
  • Study of Earthquakes
    • The study of earthquakes is known as seismology.
    • Seismologists analyze the causes, frequency, and effects of earthquakes.
    • This field includes the study of seismic waves and the Earth's internal structure.
