5% minerals 45% air and water 50% organic material
Soil covers roughly 30% of the Earth's surface.
The greatest percentage of soil is typically made up of mineral particles. These minerals come from the weathering of rocks and minerals, contributing to the physical properties of soil.
Approximately 25% of Earth's surface is covered by soil.
Loam soil typically contains around 2-3% organic matter. This percentage can vary depending on the location and management practices. Organic matter in soil is important for fertility, nutrient retention, and soil structure.
To determine the percentage of clay, silt, and sand in the soil at point X, you would need to conduct a soil analysis test. The test involves collecting soil samples, separating the particles based on size, and calculating the percentage of each component present in the soil. The percentages of clay, silt, and sand can vary depending on the location and type of soil found at point X.

Approximately 25% of Earth's surface is covered by soil.
The water content of soil is expressed as a percentage, i.e. the percentage of the soil that is water. To calculate, weigh the mass of a sample of soil. Let this be W. Then dry the soil in an oven (be careful not to burn it) and weigh the dry soil. Let this be D. The soil moisture content, M = W-D/W x 100.

The percentage of air in soil varies depending on factors like soil type, compaction, and moisture content. In general, soil samples typically contain around 25-50% of pore space, which includes both air and water.
Porosity
The average percentage of mineral matter in soil typically ranges from 40% to 60%, depending on the type of soil and its composition. Mineral matter includes inorganic materials such as sand, silt, and clay that make up the bulk of soil particles.
Approximately 58% of soil organic matter is made up of carbon.
Soil texture refers to the size of soil particles. Soil can be classified as sandy, silty, or clayey based on the percentage of each particle size present in the soil sample.
