    Study Notes

    Composition of Rock

    • The primary component of rock is minerals

    Erosion and Weathering

    • The main difference between erosion and weathering is that weathering is the breakdown of rocks into smaller particles, while erosion is the transportation of those particles away from their source

    Soil and Plant Growth

    • Soil plays a crucial role in plant growth as it provides water, nutrients, and support
    • Plants generally require water, oxygen, carbon dioxide, and minerals from the soil to grow

    Layers of the Earth

    • The Earth is composed of four distinct layers: the crust, mantle, outer core, and inner core

    Temperature of the Earth

    • As you move from the crust to the core, the temperature increases, with the core being the hottest part of the Earth
    • The temperature at the Earth's core is approximately 5,000 to 6,000 degrees Celsius, compared to the crust which is around 10 to 20 degrees Celsius

    Earth Materials

    • Soil is composed of minerals, water, air, and organic matter
    • The components of Earth materials include rocks, minerals, soil, and water
