The country has been inhabited from prehistoric times for an incredible 5,000 years and has one of the most important prehistoric sites in the world - on a hill close to Maroua in the north is a layer containing ancient stone artifacts that is almost a metre thick.〔【出典】Hiragana Times, 2003年9月号◆【出版社】株式会社ヤック企画 〕"HT203004", "2479658"
Now, when I say "ash," I don't mean that it's ash taken from when a volcano erupts, but rather volcanic stratum taken from Sakura-jima in Kagoshima Prefecture.〔【出典】Hiragana Times, 2003年3月号◆【出版社】株式会社ヤック企画 〕"HT197052", "2416269"
The fossils were found in a 4.4-million-year-old stratum in Aramis, Ethiopia.〔【出典】Catch a Wave, 2009年10月9日号◆【出版社】株式会社浜島書店 〕
Whatever their minor differences, geologists are agreed as to the vast thickness of the accumulated strata which compose the visible part of our earth, and the inconceivable immensity of the time of whose lapse they are the imperfect, but the only accessible witnesses.〔【出典】日英対訳文・対応付けデータ（独立行政法人情報通信研究機構）〕"_DARWI", "2559299"
The general fact soon became evident that none but the simplest forms of life lie lowest down, that as we climb higher among the super-imposed strata more perfect forms appear.〔【出典】日英対訳文・対応付けデータ（独立行政法人情報通信研究機構）〕"_BELFA28", "2486481"

since every detailed study of fossilized strata is, in effect, a test of the theory.〔【出典】日英対訳文・対応付けデータ（独立行政法人情報通信研究機構）〕"_CURRI", "2596378"
Of course, one might deny （as some do） that the layers of the earth represent a succession of very lengthy epochs and claim, for example, that the Grand Canyon was created in a matter of days,〔【出典】日英対訳文・対応付けデータ（独立行政法人情報通信研究機構）〕"_EVOLU", "2417429"
One popular answer to the case for evolution sketched out above proposed by anti-evolutionists is the argument that geological features like the Grand Canyon were created by divine intervention in a matter of days, so that we have no right to infer that the fossils in the higher layers were not also created at the same time as those in the lower layers.〔【出典】日英対訳文・対応付けデータ（独立行政法人情報通信研究機構）〕"_CURRI", "2424944"
The employer shall make the structure of tunnel shoring sufficiently sound corresponding to the condition of nature of the soil, strata, water content, spring water, cracks and loose stones pertaining to the natural ground where the said tunnel shoring was installed and method of excavation.〔【出典】日本法令外国語訳データベースシステム 〕
The employer shall, when carrying out the excavating work of tunnels, etc., investigate in advance the landform of natural ground and condition of the nature of the soil and strata pertaining to said excavation work by boring or other appropriate method in order to prevent workers from dangers due to cave-in, inundation, gas explosion, etc., and record the result of the investigation.〔【出典】日本法令外国語訳データベースシステム 〕
