Ok guys thanks for answering my other question, But I have another one. Which compositional layer is divided between three mechanical layers?

LayerDepth

Lithosphere0-100 km

Asthenosphere100-350 km Soft plastic *note: The mantle is not liquid!

Mesosphere350-2900km stiff plastic

Outer Core5100-6370 km solid

Explanation:

l i t o s p h e r e 0 - 100 km

a s t h e n o s p h e r e. 100 - 350 km

m e s o s p h e r e. 350 - 2900 km

o u t e r. c o r e. 5100 - 6370 km

I don't know if this helped at all but I hope it did!

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
