What are two ways that acid rain affects the environment?
Acid rain can exhibit adverse affects on the environment by leaching aluminium from the soil and by creating nitrogen pollution.
The effects of acid rain:Acid deposition or acid rain is a term, which comprise any kind of precipitation with acidic constituents like nitric acid or sulfuric acid, which fell to the ground from the atmosphere in dry or wet forms.
The ecological effects of acid rain are clearly evident in aquatic environments like lakes, streams, and marshes as it can be harmful to aquatic species and wildlife associated with it. When acid rain flows through the soil it can leach aluminum from the soil, which washes into streams and lakes.
Some kinds of animals and plants are able to withstand acidic waters and some amounts of aluminum. However, some of those which are acid-sensitive will get lost due to decline in pH.
Acid rain also comprise nitrogen, and thus it can result in nitrogen pollution in the coastal waters leading to decline in the populations of shellfish and fish in the regions. Therefore, nitrogen in the acid rain can exhibit deleterious effect on some of the ecosystems.
Thus, acid rain affects the environment by creating nitrogen pollution and by leaching aluminum from the soil components.

Why do waves move faster at higher temperatures and in a solid phase?
O There is more energy and the particles are farther apart.
O There is less energy and the particles are closer together.
O There is less energy and the particles are farther apart.
There is more energy and the particles are closer together.
Answer:
B
Explanation:I took the test if u need help follow me
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.
What is meant by intermolecular force ?Intermolecular force is defined as the force of attraction experienced between the neighboring molecules in the same state.
Here,
During higher temperature and when in a solid phase, the waves exhibit movements very faster than in other phases.
This is because, when the temperature of the system is increased, the energy of the molecules in the system will be increased to a higher level. This energy formation is in the form of kinetic energy of the molecules.
Molecules in the solid phase have a greater intermolecular force of attraction with their neighboring molecules. Therefore, the molecules in the system will be more closer to each other.
As the kinetic energy of the molecules in the system increases, the molecules will start vibrating. These vibrating molecules induces the vibration to their neighboring particles, since they are closer together.
As a result, more and more highly energetic molecules are set to vibrate, which causes the wave to move faster in the system.
Hence,
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.

10 POINTS !!! Why is it risky to build something whose natural frequency can be matched by
external vibrations?
Answer:Most objects have at least one natural frequency of vibration. If a nearby object vibrates at the same frequency, it can cause resonance. Resonance is an increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency.
Explanation:
It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance
When an object constructed has a natural frequency which is equal to the frequency of a nearby external vibration, the amplitude of the vibration of the object will increase due to the resonance effect which occurs because the external frequency matches up with the natural frequency of the constructed object.
The negative effect of resonance is the increase in the amplitude of the vibration of the object which might lead to the partial or complete collapse of the constructed object.
Hence we can conclude that It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance

Answer:
Density independent factors affect populations regardless of their size. Examples are winter, drought, forest fires. These factors are mostly abiotic (non-living). Predation affects population size.
disease
The factors that will affect a population regardless of population density is flooding. The correct option is C.
What is population?A population is the entire group about which you want to draw conclusions. A sample is the specific group from which you will collect data.
The sample size is always less than the total population size. A population for this research does not necessarily refer to people.
A population is a subset of individuals from one species that live in a specific geographic area and interbreed in reproducing species. Some species' geographic boundaries are easy to establish, while others are more difficult.
Population change is influenced by three factors: birth rate, death rate, and migration. Though one or two of these factors may have an impact on a population in a specific area, all three have an impact on population change.
Thus, the correct option is C as the population can be get affected by flooding without regarding their density.
