The 3 main layers are the crust, the mantle, and the core. The crust consists of everything you see- dirt, rock, minerals, and everything you can see. We live on the crust, and it floats around on the magma in pieces we call continents. The next layer is the mantle, which is where all the magma is- this is what the crust floats on. It consists of molten rock and minerals; the bottom layer of the crust is continually melting under the extreme heat, but it is replaced when volcanoes spew the magma back onto the surface. The last layer is the core, an extremely fast-spinning ball of heavy metals. It is split into two layers; inner and outer core. The outer core is mostly an alloy of nickel and iron with some other heavy metals thrown in, like platinum and gold, but the inner core is almost solid iron. It is so hot that it should be melted, but the pressure of everything on top of it makes it so it has nowhere to melt to, keeping it solid.

Answer:
Sleep apnea is a condition in which the patient or a person lost breathing during sleep. This occurs around 10 to 20 seconds or this period can be longer. It sometimes occurs during an arousal state. The person who is suffering from this problem may not aware that he/she has sleep apnea. It happened and they realize when they feel fatigued during their whole day. Many times person start treatment at the complaints of their partner. When they explain that they snored very loudly and in between for a short period they stop breathing. It is common among obese people and they snore very loud.
- The sleep apnea is of two types:
- The obstructive sleep apnea
- The central sleep apnea
Answer:a. Pre-contemplation, contemplation, preparation, action, maintenance, termination
Explanation:
Precontemplation - this is the stage in which people are not inclined towards taking any action to change anytime soon. They are still not convinced that they have a problem or that their behaviour will have a negative outcome. They are more concerned about the negative effect the change will bring to them and not paying attention to the positive results it would bring if they were to change their behaviour.
Contemplation -This is the stage where they start to consider changing in the future, they start to think about it.
Their eyes start to open up to the fact that their behaviour is probably negative. They start to equally evaluate both advantages and disadvantages of changing this behaviour.Eventhough they are thinking about changing their behaviour but at this point they are still resistant towards changing.
Preparation (Determination) - This is the stage where they are ready to start the path towards changing their behaviour within 30 days. They take baby steps because they can now understand that it would be healthy to do so.
Action - now they have acted and want to continue on the same direction they may start engaging in different healthy behaviors .
Maintenance - They working towards ensuring that they don't go back to the same behavior so they striving to make sure they keep what they have achieved.
Termination - this is the stage in which they are truly over their former negative behaviors. They have completely eliminated this behaviour. They are sure they will never return back however it said that this is a difficult stage to reach hence most people stay at the maintenance stage.
