Downwelling topic should be read by Pedro to understand the phenomenon.
Explanation:
The sinking and accumulation of high density material beneath the material of low density is the process of Downwelling. One such example is of- the saline water lies beneath the freshwater. It takes place in the oceanic anti-cyclonic areas where surface convergence is created.
It causes ventilation in oceans and helps in facilitating aerobic respiration in different organisms by bringing surface oxygen dissolved in water. This condition is the reason behind the survival of aerobic organism under water.
without the sun we probably be freezing that's why we need the son it keeps us warm and the sun gives use radiation energy which could help us power things.
D is correct. Newton's first law of motion states that an object in motion stays in motion. The orange is moving and then the tray stops making the orange move forward because of inertia. Hope this helps! ;)
