Yes. A tree falling over in a forest makes a sound even there is no receptor (human or animal ear) to hear it.
What is sound?In terms of physics, sound is a vibration that travels through a transmission medium like a gas, liquid, or solid as an acoustic wave. Sound is the reception of these waves and the brain's perception of them in terms of human physiology and psychology. Only acoustic waves with frequencies between roughly 20 Hz and 20 kHz, or the audio frequency range, can cause a human to have an auditory sensation.
If sound is defined as air vibrations, then the falling tree most definitely creates sound because it causes air vibrations. A recorder with a microphone could undoubtedly capture those vibrations as sound even if no one or any other animal was around to hear it.

You must use all of the tools in your design: lamp, tennis ball, golf ball, and yarn.
When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.

Taylor created the following table to compare the three types of rocks. What correction needs to be made to the information in the table?
Examples of igneous rock are sandstone and limestone and examples of sedimentary rock are granite and basalt.
Examples of igneous rock are granite and marble and examples of metamorphic rock and basalt and gneiss.
Metamorphic rocks are made from the cooling and hardening of sediment and igneous rock is made from high heat and pressure causing chemical change.
Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together.
Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together.
Igneous rocks are formed by cooling and hardening of sediment. The examples of igneous rocks include granite and basalt. Metamorphic rocks are formed by the treatment of high heat and pressure. The examples of metamorphic rocks are marble and gneiss.
What are Igneous rocks?Igneous rock or magmatic rock, is one of the three main rock types, and the other rocks being sedimentary and metamorphic rocks. Igneous rock is formed through the cooling and solidification of the magma or lava in the volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.
Metamorphic rock are formed from other type of rocks, however they have been substantially changed from their original igneous, sedimentary, or earlier metamorphic forms. Metamorphic rocks form when the rocks are subjected to high temperature, high pressure, hot mineral-rich fluids or, more commonly, some of the combination of these factors.

if you dig a hole through the earth, from one hemisphere to the other, and drop a tennis ball into it, would it get stuck at the center, since thats where gravity's at, or would it pop up out the other side??
Answer:
Depending on which hemisphere it is, like western to eastern, It would most likely get stuck at the center. You would also have to put more things into thought like acceleration, velocity, and speed.
BUT since the question asked "would it pop out the other side?", I'm assuming it's talking about northern to southern hemisphere. so in that case it would pop out the other side since gravity makes things go downwards.
Answer:
We drop a tennis ball into the hole. The stone is pulled down towards the center of the earth. It falls all the way to the middle of the earth once it reaches the middle, theres no more pull of gravity. ... It would go up a ways, then (due to the pull of gravity) fall back in the other direction, back towards the center
