Phasas Of the moon

Some important questions that Should be able to be answered from the simulation are:
What did you notice about the phases of the moon? Why do we see different parts of the moon each night? What is a lunar month?

I noticed that the angle that the sun is reflecting at and the way the moon is placed creates different shadows of the moon, this is how we have different "types of moons."
The reason that we see different types of moons every night is because the moon is rotated in a different angle, and the moon is still the same the only difference is the shade.
A lunar month is the time that it takes from one new moon to the next, usually 29,5 days

Noise Pollution

Noise Pollution

Have you ever thought about noise pollution, or noise that can hurt you. Well if you didn’t then you will after I you read this Report. I will tell you how its caused what are its effects and my opinion on it, and conclude the final sentences.

Causes:

There are many different thing that can cause noise pollution, noise pollution is unwanted it can cause problems physically and mentally. It is caused by indoor noises and outdoor noises Noise pollution can cause annoyance and aggression, hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects. The indoor noises that cause noise pollution are loud house hold objects and loud bands. There are many more outdoor noises then indoor, some of them are transport, bands, yelling, sometimes and workers that build can cause a lot of noise, there are many more different types of noise pollution. But it is important to know that we are not the only people that are affected by noise pollution such as household animals, and the environment. Noise can have a detrimental effect on animals, increasing the risk of death by changing the balance in predator or prey detection and avoidance, and interfering the use of the sounds in communication especially in relation to reproduction and in navigation. Acoustic overexposure can lead to temporary or permanent loss of hearing.

Effects:

There are different effects to noise pollution some of them are high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects. Furthermore, stress and hypertension are the leading causes to health problems, whereas tinnitus can lead to forgetfulness, severe depression and at times panic attacks. Noise pollution usually effects older men exposed to significant occupational noise demonstrate significantly reduced hearing sensitivity than their non-exposed peers, though differences in hearing sensitivity decrease at the age 60 (or older)

Conclusion:

My opinion on noise pollution is that it is mostly hurtful toward the health, but sometimes it isn’t bad, it can be (in some situation) that only the seniors can be affected by it. But in a lot of cases it causes harm sometimes even death, because if you can’t hear that’s one of the components in life that you are missing.
