Carbon dating is a process that estimates the age of anything. However, there are flaws that exist. It may not be a precise number, but it does gives a good estimation.
Sound waves are both compressional and longitudinal, (although we frequently draw them as transverse waves).
Longitudinal waves are where the particles of matter collide into one another, pushing them into the next and then oscillating back. This is how sound travels. This is also why sound can only travel through a medium, it cannot travel through a vacuum, as is shown here:
Spider monkeys live in a <span>tropical rainforest
A savanna is a grassland with VERY FEW trees.
Polar ice is like Antartica.
The desert is all sand, no trees.

The electrical impulse travels across the axon, and the myelin sheath helps to increase transmission speed.
