지구 자기장 약화

Earth's magnetic field is fading. Today it is about 10 percent weaker than it was when German mathematician Carl Friedrich Gauss started keeping tabs on it in 1845, scientists say. If the trend continues, the field may collapse altogether and then reverse. Compasses would point south instead of north. 어휘연구 fade 빛이 바래다, 소리가 시들다(wither), (기억이)쇠퇴하다(droop) His eye-sight faded.

Last year Tinseltown released The Core, a film in which the collapse of Earth's magnetic field leads to massive electrical storms, blasts of solar radiation, and birds incapable of navigation. 어휘연구 twist (명) 뒤틀림, 엉킴.

Glatzmaier is keeping an eye on our planet's weakening magnetic field as he tries to learn more about how Earth's geodynamo works. The geodynamo is the mechanism that creates our planet's magnetic field, maintains it, and causes it to reverse. 어휘연구 expert 전문가 keep an eye on 지켜보다, 주시하다 geodynamo 지구역학 Magnetic Shield Earth's geodynamo creates a magnetic field that shields most of the habited parts of our planet from charged particles that come mostly from the sun.

The field is in constant flux, scientists say. But even without it, life on Earth will continue, researchers say. 어휘연구 navigate 항해하다, (철새가) 이동하다 flux 유동, 흐름, 끊임없는 변화 Geodynamo Scientists believe the magnetic field is generated deep inside the Earth where the heat of the planet's solid inner core churns a liquid outer core of iron and nickel. The solid inner core is thought to be a mass of iron about the size of the moon that is heated to several thousand degrees Fahrenheit. Heat radiated by this inner core builds up at its boundary with Earth's liquid outer core, causing the fluid there to expand. 어휘연구 churn 교유기로 버터를 만들다, (스크류로) 거세게 돌리다. boundary 경계, 경계선 Fahrenheit 화씨 expand 팽창하다, 늘어나다 fluid 유체, 액체 “When it expands it becomes a little less dense and more buoyant. So it starts to rise. That's convection," Glatzmaier said. "Hot fluid rises, then cools off and sinks again." The convection generates an electric current and, as a result, a magnetic field. 어휘연구 buoyant 부력이 있는 convection 대류, 환류 electric current 전류
