Question

Explain the properties of bedrock in soil profiles

Answer 1

●It is made of hard and solid rock.
●It is too hard to be dug with a spade.
●Rainwater accumulates above this layer and
forms the water table.

Answer 2

Bedrock is a deposit of solid rock that is typically buried beneath soil and other broken or unconsolidated material . Bedrock is made up of igneous, sedimentary, or metamorphic rock, and it often serves as the parent material for regolith and soil. Bedrock is also a source of nitrogen in Earth’s nitrogen cycle. A bedrock deposit that occurs at Earth’s surface is called an outcrop.

These are secondary properties:

The processes of weathering and erosion affect bedrock. Outcrops exposed to wind and water are often decomposed, or weathered, over time into regolith or smaller particles. In environments characterized by humid conditions that extend for many thousands to millions of years, water may penetrate deep into bedrock to form saprolite, a rock made from the consolidation of clay minerals that remain from the chemical weathering process. The weathering of bedrock also frees large amounts of nitrogen that can be taken up by plants and other forms of life
