Hi there!
Liquid and gas phase can both allow objects to pass through them, whereas solid phase does not.
Hope this helps!

Answer:
D. Asthenosphere
Explanation:
The theory of plate tectonics states that the lithosphere which is the solid outer crust of the earth contains segmented plates that shift to the asthenosphere. The asthenosphere is the upper part of the mantle that is molten in form.
So, the ability of the plates to move over to the asthenosphere, is an important feature of the plates. There are different points in the earth where the plates merge and separate.
Answer:
5.7
Explanation:
The pH can be calculated by:
pH = -log[H⁺]
Where [H⁺] is the concentration of hydrogen ions. The pH is a way to identify if the solution is an acid or a base. When pH is equal to 7, the solution is neutral, when it is less than 7, it is acid, and when it is larger than 7, it's a base.
So, for the acid solution given, [H⁺] = 2.0x10⁻⁶ M
pH = -log(2.0x10⁻⁶)
pH = 5.7
Answer:
1.2 ( two significant digits)
Explanation:
5.4 - 4.21 answer should only have the the number of significant digits as the number in the equation with the least number of significant digits... in this case 5.4 is only two significant digits....so the answer should only have two significant digits
5.4 - 4.21 = 1.19 round to two digits = 1.2
The symbol might be in one language and the name another. For example Fe is irons symbol. Fe is ferrum, iron in Latin.
