B. the oceans is the largest ecosystem.
Answer: Density affect propagation.
Density is mass per unit volume of a substance.
A substance that is more sense has more mass per unit volume, it will make sound to transmit at slower rate . Less dense substance will allow sound to transmit at higher rates. Density affect the speed a wave will be transmitted through it. The denser the material, the slower wave will be transmitted.
Explanation:
Density is Mass per unit volume. Density affect the propagation of wave. The denser the substance, the slower wave will be transmitted through it. The less dense the material, the higher wave will be transmitted through it. Density affect the speed of wave.
A lunar eclipse happens when the Moon passes directly behind the Earth and into its shadow. This can only happen when the Sun, Earth, and Moon are aligned. Because of this, a lunar eclipse can only happen on the night of a full moon.
The moon gives off a reddish appearance during this time because the only light reaching the moon and reflected off of its surface is the light refracted by the Earth's atmosphere (the same reason a sunrise/sunset appears reddish).
A totally eclipsed full moon is also known as a Blood Moon because of it's colour
