Answer:
B.air density
Explanation:
Updraft and downdraft is the upward and downward movement of air.
It caused by differences in air densities. There could be differences in air current due to the heat that occur in the ground during the day time which makes air above more warmer than the air below. The air above is less dense as it rises above it becomes cool.
It also occur when air current moves over mountains.
Carbon is a key element found in all carbohydrate, lipids, proteins and nucleic acids, which are all organic macromolecules.
The fundamental component of all these macromolecules is carbon. The carbon atom has the unique ability to form covalent bonds with as many as four different atoms, making it the best or ideal element to form the backbone or basic structural component of the macromolecules.
Carbon easily bonds with non - metallic elements and due to this, it is termed often as the building block of life.
The answer is deposition.
Deposition is the process where different particles (such as sediments) are blown and moved to a different location, where they then settle down.
