Answer:
planet's orbital eccentricity and semi-major axis
Explanation:
The eccentricity and the semi - major axis controls the size and shape of the orbit of the planet . The value for the semi major axis is equal to the half of largest diameter of the elliptical orbit .
The eccentricity controls the shape of elliptical orbit . It is the ratio of the center to the focus ( sun ) length and the semi - major axis length .
Subsoil: This layer has normally less organic matter than the A horizon, so its colour is mainly derived from iron oxides. Iron oxides and clay minerals accumulate as a result of weathering. In a soil, where substances move down from the topsoil, this is the layer, where they accumulate.
