国科学家通过精密电脑计算，发现地球核心的温度竟高达５５００℃，几乎接近太阳的温度，亦比科学界之前估计的为高．进行研究的英国伦敦学院大学强调，地核蕴藏大量热能，产生地震、火山爆发及板块移动，故了解地核深度，对了解地球变化有直接帮助．地核中主要物质为液态铁， Through precise computer calculations, scientists in the country discovered that the temperature of the Earth’s core was as high as 5,500°C, which was almost close to the temperature of the Sun, and was also higher than the scientific community had previously estimated. The University of London’s London University under study emphasized that the Earth’s core contains a lot of heat energy and generates earthquakes, volcanic eruptions and plate movements. Therefore, understanding the depth of the Earth’s core has a direct impact on understanding the Earth’s changes. The main material in the core is liquid iron.
