What would you like to do?
Is there a sound associated with Earth's rotation and if so can any animals hear it?
The Earth is rotating on its axis as a single body, spinning in a vacuum. The atmosphere is pulled along with the rotation, so there are not any things moving at different speeds to make any kind of noise. However, the fact that the Earth rotates is a major factor in the creation of weather, and there are many noises associated with that, which many animals can hear, including us.

Thanks for the feedback!
\n. \n Stopping Earth's Rotation \n. \nIt would be extremely difficult. You would have to somehow put an unbalanced force opposite the initial direction of rotation. I… can think of two ways to do that:\n. \n1: direct an external body into a location on the surface so that the combined system would have zero angular momentum\n2: Use a mass driver to throw mass away from the earth at high speed.\n. \nFor option 1, you might be able to run an asteroid . \nThe second moment of the earth is something like 10^38 kg?m2, and its angular velocity is 2*pi/86400 radians/sec. \nAn "asteroid" with a mass of, say 10% of the earth would have to impart an opposite angular momentum, so it\ncould have a velocity \n. \nrmv = I*omega\nv= 10^38 kg?m2 * 2*pi/86400 rad/sec / (6.4 e6 m * 0.1 * 6x10^24 kg)\n. \nwhich is a mere 1.9 km/s, if my calculations are correct. So you could probably get better results with\nan asteroid that is 1% of the mass of the earth, but had velocity of 19 km/s, about how fast the earth moves\naround the sun. Ceres has a mass much less than this(1x10^21 kg vs 5x10^24 kg), so it would have\nto be tossed in appropriately faster.\n. \nThis is all vector stuff, so you would have to get it in just the right direction, too. For example, it \ncould fly fly in from due east and crash into Venezuela, thereby stopping the rotation of the earth and\nending the regime of of Hugo Chavez. The benefits of either of these effects are left as an exercise to the student.\n. \nIt would seem that this probably happened to Venus at some time in the past, since it has basically no\nrotational angular momentum now. Very strange.\n. \nThe other alternative could be enacted by building a string of nuclear generating stations along the equator, \nthen using them to toss mass eastward into space. Suppose you tossed mass out in 1 kg pills at somewhat \nabove escape velocity, say 10 km/s for the sake of argument. Since the station is 6400 km from the axis\nof the earth, then each would take away rmv=6400 km * 1 kg * 10 km/s = 64x10^9 kg m2 of angular momentum.\nYou would need to toss off \nN = I*omega/h\n= 1.14e23 \nof these things to stop the earth.\nThe energy required to accelerate them would be \n1/2 mv2\n= 50 MJ.\n. \nSince a decent nuke plant can generate about 1 GJ/s, one reactor could generate enough to fire off\n20 projectiles a second. Tossing off 1.14e23 of them would take about 180 quadrillion years, or about\n10000 times as long as the universe has been around.\n. \nThe value of this exercise has also not been demonstrated.
One animal that does this is the rabbit. You will also see a lot of cats that movie their hears so they can hear things better.
worms,fish,snakes,crocodiles,sharks, and bats
Pigs Do I Think, When They Hear A Loud Noise Their Ears Twitch
fish, rabbit, lizzard, turtle giraffe
yes, crickets have their ears in their knees, so they hear with their legs.
While dogs can hear high frequency sounds, BATS may hold the record. They use high frequency sound for navigation. actually there are 2. dolphins and mice Beluga Whale and ba…ts
The most common animals that can hear infrasonic sound are as Follows : 1) Fish 2)Dogs 3)Whales
Animals that can hear infrasonic sounds are; frogs snakes ants dogs fishes whales beetles pigeons Usally, small animals can hear infrasonic sounds because they catches low fre…quency sound which is less than 20 Hz, especially insects. You may have observed that even if you walk very softly on the floor, animals like dogs feels your coming because they can hear infrasonic sounds.
The rotation of the Earth is the Earth spinning on its axis, the pole extending from north to south, once every 23 hours 56 minutes and 4 seconds, roughly. Revolution is th…e word describing earth's yearly orbit around the sun. There are several implications of the Earth's rottation, for example: days and nights, timezones, different length of the daytime during the year (it's because rotation, revolution and axial tilt of the Earth). You can observe Earth's rotation, solar time changing, seasonal Earth's time changing etc. on Earth Time Clock (see: related links)
No, most animals can hear higher frequencies than humans. The range for humans is 20 Hz- 20,000Hz, while most animals' ranges are much higher.
whale can hear ultrasonic sound waves.
Many animals have a higher range of sounds they can hear but humans cannot. Dogs for example, can hear sounds as high as 60,000 Hz while the human range is within 20,000Hz. Lo…wer base ranges 20 to 80 Hz are felt more than heard in many animals so while they will react, it is more fright and flight than recognition of specific sound.
