Answer:
There is no drawing here to label but I will go on to explain the the various types of waves with a diagram
Explanation:
P wave or the primary waves are the fastest waves in seismic waves. It is usually the first to arrive at seismic station. P waves are called compressional waves because they have ability to pull and push rocks as they pass through them. It is the first waves you notice during an earthquake.
S waves or the secondary waves is slower than the primary waves and moves through solid rocks and can not pass through liquid. It travels outside the earth core, and that has made seismologist to believe that the outer crust is liquid. It moves rocks up and down, side by side.
Surface Waves only travel through the earth crust. It is slower than P and S waves. It is the surface waves that cause physical destruction we notice during earthquake. The strength and extent of damage of surface waves is determined by the depth of the earthquake.

PUT THIS IN YOUR OWN WORDS SO YOU DON'T GET COPYRIGHTED
Mr/Mrs.logger, in this letter I would like to persuade you to stop cutting down trees. It will help the economy, you can find a new job, and you will understand that being greedy is not okay. Keep reading on to understand why. Thank you!
Cutting down trees in this state is illegal. I understand you are trying to help your family by making money. But, there are many other ways to do so like, helping people build fences, go to a store and be a cashier, help people move things, etc. Finding another job could help you put food on your family's table and not send you to jail.
If that didn't persuade you to look at the Amazon Rainforest for refrence, people took down those trees to help support their family but it only ended up destroying another family's home. All of these creatures lost their homes that they had to keep their family safe, warm, alive. But, all those loggers did was put these animals on the brink of extinction just to help their own families. And, the Amazon Rainforest is very important and needed in this world. It is one of the many reasons that earth is habitable, it's water cycle's, the many tree's giving off Co2, it is also home to 30 million people! and over 10% of the world's biodiversity! That's a lot. And, the tree's that you are cutting down could someday be a rainforest that will contain millions of people. So really think about it, think about what you are doing to the world, think about how you can fix it.
So I hope that I was able to persuade you to learn to do something else that won't ruin or economy, I mean we all mess up with something that will make our Co2 footprint bigger but there are many ways to try and fix that like tyring to make a compost garden, plant a garden, do anything that will help your family and the animals/plants surrounding you.
