Answer: Deeper in the soil, the organic pigment coats surfaces of soil, making them darker than the color inside. Humus color decreases with depth and iron pigments become more apparent.
What causes differences in soil types?
Temperature and precipitation are the main climate factors that make soils different from one another. Precipitation determines how much water moves through the soil, and minerals and salts dissolve in, and move with, the water. Soils also differ from one another thanks to the shape of the landscape, or relief.

What is 90% of the biological stuff in soil?
Soil is generally composed of 50 percent solid material and 50 percent space. About 90 percent of the solid portion of soil is composed of tiny bits of rock and minerals. These solid particles range in size from fine clay to mid-range silt to relatively large, coarse sand.
What are soil features?
Soil is made up of solid, liquid and gas components: • the solid part consists of mineral particles and organic matter • the liquid part is water and nutrients • the gas part is air. The solid components are minerals derived originally from weathering rock and organic materials derived from plants and micro- organisms.
What is structure of a soil?
Soil structure describes the arrangement or the way of soil in of the solid parts of the soil and of the pore space located between them. It is determined by how individual soil granules clump, bind together, and aggregate, resulting in the arrangement of soil pores between them.
Why the soil is important?
Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites.
How soil is important to animals?
Soil is essential to every animal on earth. It is a critical part in providing food, water, air, and habitat to animals. One of the most important reasons animals depend on soil is because it allows for their food to grow. Plants are a main source of food for herbivores, omnivores and even carnivores!
