Bedrock is most likely found in Dhorizon.

Explanation:

In R horizon Bedrock material is most likely to be found. The parallel layer to the surface of the Earth is known as the Soil Horizon. It is different from other layers of Earth’s surface in terms of chemical, biological and physical characteristics.

Among the all soil profiles r horizon is mainly known for composition of hard rock masses. It is a layer which has partially withered or completely un-withered rocks at its base. It is similar to the parent material.

the scientific method.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
