    Learning Objectives
    • Explain what a rock is.
    • Summarize the main characteristics of igneous, sedimentary, and metamorphic rocks.
    • Describe the rock cycle and the types of processes that lead to the formation of igneous, sedimentary, and metamorphic rocks.
    • Explain why there is an active rock cycle on Earth.

    • 6.1: What Is A Rock?
      This page explains that rocks are solid formations made of various geological materials, including minerals and organic matter. They are classified into three main types: igneous (from cooled molten rock), sedimentary (from compressed fragments or mineral deposits), and metamorphic (from heat and pressure). Recognizing these categories is essential for identifying different rock types.
    • 6.2: The Rock Cycle
      This page explains the rock cycle, a continuous process of transformation among igneous, sedimentary, and metamorphic rocks, driven by Earth's heat and the hydrological cycle. It highlights key processes such as magma cooling, weathering and erosion into sediments, and metamorphosis under extreme conditions. Unlike a life cycle, the rock cycle allows for various pathways of change, remaining active due to Earth's heat, atmosphere, and water.
    • 6.3: Chapter 6 Summary and Key Term Check
      This page introduces rocks as solid masses composed of geological materials, detailing the three main types: igneous (from molten rock), sedimentary (from fragments or crystals), and metamorphic (altered by heat and pressure). It explains the rock cycle as a framework illustrating how rocks change types, influenced by Earth's internal heat and surface solar energy.
