Answer:
Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
Explanation:
Explanation:
The temperature of the environment plays an important to differentiate the noise level between sunny and a cloudy day.In the sunny day air have high temperature due to sun and temperature of decreases when altitude increases.Due to this temperature difference the sound waves refract upward or we can say that away from the earth and causes the lower noise level.ON the other hand in cloudy day the temperature of air is low due to this the temperature of earth is also low .Due to this sound wave return back in to ground and cause the high noise level.
The wind will also alter the direction of sound by the mechanism of refraction.When wind is flowing along the sound propagation the heard sound will be loud on the other hand when flowing apposite to the propagation of sound wave then heard sound level will be low.
So among these two direction of wind can significantly impact the direction of flow of sound.
High and low pressure system both bring changes in weather.
Answer: Option D
<u>Explanation:</u>
There are certain areas which are affected by high pressure of air and some are affected by low pressure of air. This high and low pressure of air is caused by the ascending and descending of air.
But both affect the weather and causes a change in it. Due to the high pressure of air, weather becomes cold and dry and on the opposite side, because of low pressure of air, there is formation of clouds and rain.
