Answer: A constructive plate boundary creates ridges
Explanation: A constructive plate boundary, sometimes called a divergent plate margin, occurs when two tectonic plates move apart. Volcanoes are formed as magma wells up to fill the gap and molten rocks from the mantle below spread out and harden, eventually forming a ridge of new land/rock. The Mid-Atlantic ridge is an example of a constructive plate boundary.

Explanation:
The formula for calculation of EROI is :
![EROI=\frac {\text{Energy delivered}}{\text{Energy required to deliver energy}}](https://tex.z-dn.net/?f=EROI%3D%5Cfrac%20%7B%5Ctext%7BEnergy%20delivered%7D%7D%7B%5Ctext%7BEnergy%20required%20to%20deliver%20energy%7D%7D)
Thus,
Energy returned = 20 MW
Energy invested = 5 MW
So,
![EROI=\frac {\text{Energy delivered}}{\text{Energy required to deliver energy}}=\frac {20\ MW}{5\ MW}=4](https://tex.z-dn.net/?f=EROI%3D%5Cfrac%20%7B%5Ctext%7BEnergy%20delivered%7D%7D%7B%5Ctext%7BEnergy%20required%20to%20deliver%20energy%7D%7D%3D%5Cfrac%20%7B20%5C%20MW%7D%7B5%5C%20MW%7D%3D4)
<u>The EROI of the process will be 4.</u>
Lava that cools so quickly that the ions do not have time to arrange themselves into crystals with definite shape will form igneous rocks with FINE GRAINED TEXTURE. Igneous rocks are those rocks formed as a result of cooling of magma or lava.
