Because we can hear it. The medium air can tranport the sound. In a vacuum like on the moon that is not possible.
no light is the fastest on earth
mwah!! the sexiest sound on earth.
sound requires a medium, such as air, to travel. Space is a vacuum, so sound doesn't travel from the sun to earth.
The speed of sound varies depending on the medium it is traveling through. In Earth's atmosphere, the speed of sound is about 343 meters per second. On Mars, where the atmosphere is much thinner, the speed of sound would be slower than on Earth. Therefore, the speed of sound from Mars to Earth would be slower than 343 meters per second.
Earth is pronounced as /ərθ/ with a short 'u' sound in the first syllable and a 'th' sound in the second syllable.
Usually, it's not a sound we can comprehend with our human ears.
No, the words "ear" and "earth" do not have the same vowel sound. In phonetics, "ear" has the vowel sound /ɪər/ (as in "beer"), while "earth" has the vowel sound /ɜːr/ (as in "herd"). The vowel sound in "ear" is a diphthong, combining two vowel sounds, while the vowel sound in "earth" is a long monophthong.
Rrr
without the atmosphere the will stay on earth and without air there is no sound
"sound waves"
the first one to hear a sound is obviously the first man on the earth!
Earth, air, and water can carry sound waves.
