A rift is a dropped zone at the point where the plates are moving apart. As the plates move apart the crust widens and thins, valley and volcanoes begin to form in and around the area. At the start of the rift formation streams and rivers flow into the low valley and long lakes can be created.
However in many cases, there are a select few items that withstand the inferno. The average house fire burns at a temperature of about 1,100 degrees Fahrenheit, which isnât hot enough to destroy most metals and earthly-made substances. And if an item is well-placed and small in size, its chances of survival increase drastically.
Radiant heat pre-heats the fuel in front of the fire, making the fuel even more flammable. For every 10Ë slope, the fire will double its speed. For example, if a fire is travelling at 5 km per hour along flat ground and it hits a 10Ë slope it will double in speed to 10 km per hour up the hill. By increasing in speed the fire also increases in intensity, becoming even hotter. The opposite applies to a fire travelling downhill. The flames reach less fuel, and less radiant heat pre-heats the fuel in front of the fire. For every 10Ë of downhill slope, the fire will halve its speed. Fires tend to move more slowly as the slope decreases.
