Answer:
Winnowing
Explanation:
When you winnow grain, you separate the chaff from the edible grain. Flailing: Flailing is a process of threshing the grain with a wooden bar. Treading: Treading is a process of threshing the grain by stepping on it.
Fossilization is a process that requires certain conditions so that it can take place. The climate is very important, a hot and wet place is not a place where there's a chance of finding fossils, while the places with permafrost are a much better candidate because the bacteria can not dissolve the organisms. The pressure also can play a vital role. A place that manages to keep the organisms safe from outside influence, like the tar pits, are excellent preservers. Also the structure of the organisms play a key role, a boneless organism is very hard to preserve and be fossilized, while an organism with bone structure has a bigger chance of being preserved.

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 .
