Soil is an important and dynamic
resource linked to everything around
us and performs many important
roles in sustaining life on Earth.
Important Roles of Soil
Soil Provides food and
Soil controls and regulates
Soil stores gasses such as
CO₂ which maintains the
balance of temperature &
Moisture of our Earth
Soil also provides valued habitat

Sand, gravel, stones and ore
Moss and coal for heating
Soil also preserves cultural
and archaeological heritage
Problems with Soil
Soil erosion is caused by wind and rain
The clearing of land for farming, residential,
and commercial use can quickly destroy soil
Soil characteristics, components and the
formation properties affect many processes in
the soil that make it suitable for agricultural
practices. Texture, structure, and formation and
retention of water, air and solids in the soil, are
influential to plants growth and organisms.
Therefore, understanding and recognizing soil
properties and their connections with one
