    • D.

      Texture depends on the age of the soil; older soil is much finer than new soil.

    Correct Answer
    A. The size of the grains and the amount of space between grains.
    Explanation
    The texture of different kinds of soil is determined by the size of the grains and the amount of space between grains. The size of the grains refers to the particle size of the soil, which can range from sand (largest particles) to silt (medium-sized particles) to clay (smallest particles). The amount of space between grains, also known as pore space, affects the soil's ability to hold water and nutrients. So, the size of the grains and the amount of space between them play a crucial role in determining the texture of soil.

    Pablo is studying different types of soil.  He is comparing clay, loam, sand, and silt.  Which soil will Pablo find to be made of the largest particles?

    • A.

      Clay

    • B.

      Loam

    • C.

      Sand

    • D.

      Silt

    Correct Answer
    C. Sand
    Explanation
    Sand is the correct answer because it is composed of the largest particles compared to clay, loam, and silt. Sand particles are larger in size and have a gritty texture, making them easily distinguishable. Clay, on the other hand, is composed of tiny particles that are smooth and sticky when wet. Loam is a mixture of sand, silt, and clay, so it does not have the largest particles. Silt particles are smaller than sand but larger than clay. Therefore, sand is the soil type with the largest particles.

    Soil with a high water-holding capacity has a texture which is

    • A.

      Spongy and loose

    • B.

      Gritty and granular

    • C.

      Wet and muddy

    • D.

      Clay-like and dense

    Correct Answer
    D. Clay-like and dense
    Explanation
    Soil with a high water-holding capacity is clay-like and dense. Clay soils have small particles that are closely packed together, creating a dense texture. This density allows the soil to hold onto water for longer periods of time, as the small spaces between the particles trap the water. The clay-like texture also helps to retain moisture, preventing it from quickly draining away. This type of soil is beneficial for plants that require consistent moisture, as it provides a steady supply of water to the roots.
