Back

The two main types of weathering are mechanical (physical) weathering and chemical weathering.

Front

What is soil?

Back

Soil is a natural resource composed of minerals, organic matter, water, and air that supports plant life.

Front

What role does organic matter play in soil formation?

Back

Organic matter provides essential nutrients for plant growth and improves soil structure.

Front

What is parent material in soil formation?

Back

Parent material is the underlying geological material from which soil develops.

Front

How does time affect soil development?

Back

Over time, soil undergoes changes in composition and structure, leading to more developed and fertile soil.

Front

What is biota in the context of soil?

Back

Biota refers to the living organisms in the soil, including plants, animals, and microorganisms, which contribute to soil health.

Back

Deposition is the process by which sediments are laid down in new locations, contributing to landform development.
