| 单词 | radioactive dating |
| 例句 | Parts of geology rely heavily on physics, such as radioactive dating of rocks, earthquake analysis, and heat transfer in the Earth. College Physics for AP Courses 2015-08-12T00:00:00Z We will explore some of the most common types of radioactive dating and how the particular isotopes work for each type. Chemistry 2019-02-14T00:00:00Z This result is similar to the age determined for the maria from radioactive dating of returned samples—3.3 to 3.8 billion years old. Astronomy 2016-10-13T00:00:00Z The discovery of radioactivity and radioactive dating enabled geologists to determine the age of certain rocks and fossils. Miller & Levine Biology 2018-01-01T00:00:00Z But new radioactive dating techniques suggest Mrs Ples, and the others discovered around her, are actually one million years older than thought. Fossils: Cave woman one million years older than thought 2022-06-28T04:00:00Z The Earth is generally assumed to be roughly 4.7 billion years old, utilizing radioactive dating that uses uranium decay, according to NASA. Astronomers created a 'cosmic cheat sheet' to help look for aliens 2019-07-12T04:00:00Z In general, radioactive dating only works for about 10 half-lives; therefore, the limit for carbon-14 dating is about 57,000 years. Chemistry 2019-02-14T00:00:00Z Yet the radioactive dating of highland samples showed that they are only a little older than the maria, typically 4.2 billion years rather than 3.8 billion years. Astronomy 2016-10-13T00:00:00Z The scientists were also surprised when they received results of the radioactive dating of 11 mounds. A Metropolis of 200 Million Termite Mounds Was Hidden in Plain Sight 2018-11-20T05:00:00Z Using a new and improved radioactive dating technique, researchers discovered that paintings in three different caves were created more than 64,800 years ago. Ancient cave paintings turn out to be by Neanderthals, not modern humans 2018-02-22T05:00:00Z Using radioactive dating techniques, the team found that the creature lived about 300,000 years ago. Giant wombatlike creatures migrated across Australia 300,000 years ago 2017-09-26T04:00:00Z Carbon-14, the isotope that archeologists use in radioactive dating, is cosmogenic—continuously created in Earth’s uppermost atmosphere by cosmic-ray collisions. Earth’s Mysterious Magnetic Field, Stored in a Jar 2017-02-13T05:00:00Z Once lunar samples were brought back by the Apollo astronauts, the radioactive dating techniques that had been developed for Earth were applied to them. Astronomy 2016-10-13T00:00:00Z Using this method of biological radioactive dating, the researchers found that some of the most long-lasting proteins in the body are components of the perineuronal nets. Why Binge Drinking May Wire the Brain for Alcohol Dependence 2015-10-23T04:00:00Z Researchers painstakingly examined each core millimeter by millimeter, using radioactive dating to determine the age of each sample. Study Strengthens Link Between El Niño and Climate Change 2013-01-04T16:15:01.277Z AMS is a method of determining the age of a sample through radioactive dating, such as Carbon-14 dating.
