What three general kinds of body parts do sound waves travel through before they reach the brain?
Sound waves travel through the outer ear, middle ear, and inner ear before they reach the brain. In the outer ear, sound waves are collected by the ear canal and directed to the eardrum. Then, in the middle ear, the sound waves cause the three tiny bones (hammer, anvil, and stirrup) to vibrate. Finally, in the inner ear, the vibrations are transformed into electrical signals that are sent to the brain via the auditory nerve.
What is one way the scientists know the outer core is liquid?
some kinds of seismic waves cannot travel through liquids, such as the outer core.

What kinds of cells are no longer undergoing mitosis?
Brain cells
How do seismic waves tell us about the properties of the outer and inner core?
We know about the nature of the different kinds of waves because each earthquake produces three kinds of wave: Primary, Secondary and Long (or another variation) waves. L waves only travel at the surface, so these are irrelevant to this question. P waves are longitudinal and can travel through solids and liquids; S waves can only travel through solids. Thus, when P waves travel through the core, but S waves don't, we know the outer core is liquid. We know that the inner core is solid because the amount of refraction of the P waves changes within the core, so it cannot be uniform in composition, so we believe it to have a solid element to it.

Does air travel through solids liquids and gases?
Air can travel through some kinds of solids, if they are porous. Otherwise it can't. It can travel through liquids in the form of bubbles. It does not exactly travel through gases so much as mix with them.
Can sound travel through other kinds of material than air if so does it travel differently?
Sound can travel through all matter. The speed at which it travels depends on the density of the material.
What kinds of space and matter can light travel through?
Light can travel through empty space, air, water, and transparent materials such as glass or some plastics. However, it cannot travel through opaque objects like walls, metals, or thick fog.
Can sound waves move through any kinds of matter?
Yes. Sound cannot travel in a vacuum.
Does waves need a medium to travel through?
No. Electromagnetic waves travel through vacuum ( ie space where there is nothing)
Is it true that different kinds of E-M waves travel through space at different speeds?
No. All E-M waves travel through space at the same speed, known as the"Speed of Light".
What kinds of plants do seahorses eat?
brain coral
How come you need a brain?
To write these kinds of questions...
What is one way that scientist the outer core is liquid?
some kinds of seismic waves cannot travel through liquids, such as the outer core.
What are the four kinds of waves that travel through the earth involved with earthquakes?
The Primary wave, the secondary wave, the surface wave, and the seismic wave
What kinds of energy travel through matter?
Mechanical, thermal, and electromagnetic energy can travel through matter. Mechanical energy involves the movement of objects or particles within a substance. Thermal energy is the movement of heat through matter. Electromagnetic energy, such as light or radio waves, can also pass through various types of material.
