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.

<h3>What is pH?</h3>
The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.
The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.
⇒pH = -log()
Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.

Explanation:
yes you got the right idea
Answer:
Mountainous roads are winding and gently sloping in order to reduce the effect of steepness which causes more downward gravitational pull to the vehicles on it. A steeper sloped road would slow the car down to a greater extent that an gently sloping one.
