Why is soil described as an interface?
When Earth is viewed as a system, soil is referred to as an interface -- a common boundary where different parts of a system interact. Soil forms where the geosphere, the atmosphere, the hydrosphere, and the biosphere meet. Over time, soil gradually evolves to a state of equilibrium w/ the environment.
Why is soil formation the first stage of primary succession?
Over a very long period of time , a series of organisms live and die on the rock.As the organisms live and die, the rock is slowly transformed into soil.
How does time affect soil?
· Soils change over time as they weather. Weathering in the soil takes place over thousands of years.

How do rock particles from a mountain become part of the soil in a valley?
Over time, the rock sides of the mountain will erode.
Does hot lava become rock or soil?
It cools to form igneous rock, which over time may be eroded down to become a component of the soil. The larger contributor to rich soil around volcanoes is the ash which settles after an eruption.

How does soil form from bare rocks?
Weathering and erosion produce ever smaller rock particles which, when mixed with dust and decayed organic matter over time, result in different types of soil.
What evolves over time?
birds such as hawks and eagles evolved from raptors
What layer of soil was dinosaur bones found in?
Fossils are not found in the soil. They are found in layers of rock after time.

Why parent material control soil formation?
Are the rocks,boulders,stones ect. That has been weathered over a certain geological period of time ,breaking down the rocks,boulders ect into smaller rock particles and then into smaller rock particles until they become the soil

How do you account the shortage of feldspar in the soil?
It is easily chemically weather, so it gone by the time a rock becomes a soil.
