Answer:
Fractional distillation
Explanation:
The process of separating petroleum products into its fractions is called fractional distillation.
Fractional distillation is a method of separating a mixture of substances based on the differences in their boiling points.
Petroleum is a mixture of hydrocarbons separated in a large fractionation tower having many trays maintained at different temperatures.
As the vapor containing the petroleum mixture ascends the fractionation tower, the mixture is separated at each tray to yield the various fractions of petroleum.
The color, shape, volume, mass, etc.

Answer:
Weathering, Erosion
Explanation:
Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.
Tree root systems have a handful of large roots that branch out into a network of smaller roots that often extend out far beyond their branches do. These root systems prevent erosion by holding the soil in place and improving drainage which helps water get absorbed into the soil instead of just running over the top.
Hope this helps
