Ok ok no fret im here to help as best as i can :) Weathering is a process that breaks down or changes rocks into smaller
pieces. Various atmospheric aspects are responsible for weathering
processes. Weathering is different from erosion. Erosion is the movement
of rock pieces and sediment from one area to another. Weathering is the
breaking down of rocks and erosion is a wearing away of rocks. There
are two main types of weathering: physical (or mechanical) weathering
and chemical weathering. Quite often, both forms of weathering will
occur together
Physical weathering is also known as mechanical weathering. This type of
weathering occurs when rocks and other landforms are broken down by
physical factors in the environment. These physical factors include
wind, water, sun, ice and temperature changes
<u>Option-(D):</u> The immediate energy source that drives ATP synthesis by ATP synthase during oxidative phosphorylation is the <u>flow of electrons down the electron transport chain.</u>
Explanation:
The creation of optimum level of energy for the processing of different activities inside the cellular system and over all body of the living being is carried out by the mitochondria which serves the purpose of a power house for the whole cellular body.
As, the creation of energy molecules is done after the Adenosine triphosphate is converted and this whole process involves a very specific nature of electron transport chain inside the mitochondria.
