Answer:
A producing colored sparks in fireworks
C rusting in the presence of water and oxygen
these are the correct answers
Answer:
Winds
Explanation:
Winds only act on oceans surfaces. The winds move the upper layers of ocean waters due to drag as they blow in the atmosphere. They are the reason for waves. However, the effects of winds cannot be felt in deep oceans where much of the movement is dependent on variable densities of ocean currents (due to differences in temperatures and salinity levels).

FULL ARTICLE
Density-independent factor, also called limiting factor, in ecology, any force that affects the size of a population of living things regardless of the density of the population (the number of individuals per unit area). Density-independent factors often arise from physical and chemical (rather than biological) phenomena.

Such factors stemming from weather and climate—as well as flooding, wildfires, landslides, and other disasters—affect a population of living things whether individuals are clustered close together or spaced far apart. For example, for most organisms that breathe oxygen, oxygen availability is a density-independent factor; if oxygen concentrations decline or breathable oxygen is suddenly made unavailable, such as when oxygen-using plants are covered by rising floodwaters, those organisms perish and populations of the various affected plant species decline.
The dynamics of most populations of living things are influenced by a combination of density-independent factors and density-dependent factors (that is, those factors that emerge when the concentrations of individuals in a population rise above a certain level). The relative importance of these factors varies among species and populations.
