what are physical features of soil?

Physical properties of soil include color, texture, structure, porosity, density, consistence, temperature, and air. Colors of soils vary widely and indicate such important properties as organic matter, water, and redox conditions.

1996). Most commonly used characteristics for cohesive soils are boundaries of fine-stratification, grain-size distribution, consistency limits, maximum and minimum density, specific gravity, organic matter, moisture content, dry density, porosity, permeability, void ratio, compression index, and shear strength.

here are some of the physical and human characteristics of Ancient Egypt. Physical - The soil is very fertile on the banks of the Nile River. Both sides of Ancient and Current Egypt were surrounded by desert, mainly to protect them from neighboring hostile tribes and/or civilizations.

Five factors of soil formation. Scientists attribute soil formation to the following factors: Parent material, climate, biota (organisms), topography and time.

['Mineral composition – knowing the mineral composition of the soil, we can predict its ability to retain plant nutrients. ... ', 'Soil pH – Soil pH is important in maintaining proper soil fertility. ... ', 'Soil Texture – Different sized minerals particles give the soil its structure – sand, silt a clay.']

Places are jointly characterized by their physical and human properties. Their physical characteristics include landforms, climate, soils, and hydrology. Things such as language, religion, political systems, economic systems, and population distribution are examples of human characteristics.

Physical characteristics include land forms, climate, soil, and natural vegetation. For example, the peaks and valleys of the Rocky Mountains form a physical region. Some regions are distinguished by human characteristics. These may include economic, social, political, and cultural characteristics.

Soils develop because of the weathering of materials on Earth's surface, including the mechanical breakup of rocks, and the chemical weathering of minerals. Soil development is facilitated by the downward percolation of water.

Soil Composition Components of soil: The four major components of soil are shown: inorganic minerals, organic matter, water, and air. The amount of each of the four major components of soil depends on the quantity of vegetation, soil compaction, and water present in the soil.

Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead. These soil components fall into two categories.

A typical potting soil may contain peat moss, bark and organic materials such as sawdust. The properties of potting soils contrast with topsoil – while topsoil is dense and heavy, potting soil is light and fluffy. While topsoil retains water and doesn't drain well, potting soil doesn't hold water and drains easily.

Soil texture is not a factor which is responsible for the soil formation. Parent material (minerals and nutrients), Time, Climate, Relief and Organisms are the factors which are responsible for the soil formation.

Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

The layers of soil can easily be observed by their color and size of particles. The main layers of the soil are topsoil, subsoil and the parent rock. Each layer has its own characteristics.
