Scientists have thought that magmas that form new crust at fast-spreading ridges rise up from the depths, quickly crystallize, and then push away from the ridge to form new ocean floor.
To stop a computer from overheating never keep a cloth or something else on the CPU or monitor. Also use the save energy option from properties so as to switch off the monitor when not in use. This will always help in keeping the computer cool and not overheating it.
A few seconds after the start of the SCRAM, a massive power spike occurred, the core overheated, and seconds later this overheating resulted in the initial explosion. Some of the fuel rods fractured, blocking the control rod columns and causing the control rods to become stuck at one-third insertion.
