To answer these questions, we must consider the properties and behavior of magma. Once magma forms, it rises toward Earth's surface because it is less dense than surrounding rock. As it rises, two changes 0ccur. First, it cools as enters shallower and cooler levels of Earth. Second, press...
题目Geothermal(地热的) power generation is one of our most stable renewable energy resources.Heat generated below the Earth's surface can provide an almost unlimited supply to power and heat homes.And while geothermal electricity only accounts for around one percent of global gen...
According to Dr. Luca De Siena from the University of Aberdeen, magma from the hot zone was not able to penetrate the surface in the 1980s due to a 1-2 km-deep rock formation that blocked its path. However, as a result of the rock blockade, the pressure may have been released along...
