Earth’s Inner CoreScientists have long struggled to understand what lies at the planet’s center, Directobservation of its center is impossible,so researchers must___(51)to other evidence. In 1889,a German scientist detected a severe earthquake in Japan.Geophysicists concluded that shock waves__...
We know that the interior of Earth is arranged in this way due to decades of study by Earth scientists. They did so by examining the behaviour and timing of seismic waves travelling through the planet in the wake of earthquakes...
difficult to study, the Earth's core has eluded scientists for centuries. Existing knowledge is largely based on comparing the aftershocks of earthquakes with echoes on the other side of the planet. Studying changes in the waves offers a glimpse of the nature and density of the Earth's ...
Steven A. Hauck II, professor and chair of earth, environmental and planetary sciences atCase Western Reserve Universityin Ohio, notes that some earth scientists concentrate on water while others focus on oceans or rocks. Earth scientists may examine the Earth's core or its magnetic field, he sa...
Then there's latent heat, Marone says. This type arises from the core's expanding as the Earth cools from the inside out. Just as freezing water turns to ice, that liquid metal is turning solid—and adding volume in the process. "The inner core is becoming larger by about a centimeter...
Businesses must take the lead in mitigating climate change's effects. Learn why environmental, social, and governance (ESG) investing is a key step.
Back on Earth, beneath a mountain in Italy, theLNGS's XENON1Tis hunting for signs of interactions after WIMPs collide with xenon atoms. "A new phase in the race to detect dark matter with ultra-low background massive detectors on Earth has just begun with XENON1T," project spokesperson Ele...
Satellite internet works by using satellites in Earth’s orbit to transmit data between a home or business and the internet backbone, the core network infrastructure that forms the foundation of the global internet. To access satellite internet, users must install a satellite dish on their roof or...
