Surface exposure dating is a collection of geochronological techniques for estimating the length of time that a rock has been exposed at or near Earth's surface. Surface exposure dating is used to date glacial advances and retreats, erosion history, lava flows, meteorite impacts, rock slides, fault scarps, cave development, and other geological events.
Dating of 28 tors on Dartmoor showed that most are surprisingly young, less than 100,000 years of surface exposure, with none over 200,000 years old. [8] They probably emerged at the start of the last major ice age . By contrast the Scottish Cairngorms, which is the other classic granite tor concentration in Britain, the oldest tors dated are ...
It has been suggested that to stabilize Earth's energy budget and thus cease warming, 1–2% of the Earth's surface (area equivalent to over half of Sahara) would need to be covered with these emitters, at the deployment cost of $1.25–2.5 trillion. While low next to the estimated $20 trillion saved by limiting the warming to 1.5 °C (2.7 °F ...
Current and former Verizon customers who purchased postpaid wireless or data service plans and were charged an "Administrative Charge" and/or an "Administrative and Telco Recovery charge" between ...
Postglacial Sea level Rise Curve and Meltwater Pulses (MWP) Meltwater pulse 1B (MWP1b) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of either rapid or just accelerated post-glacial sea level rise that some hypothesize to have occurred between 11,500 and 11,200 years ago at the beginning of the Holocene and after the end of the Younger Dryas.

Protection Agency were used. We found that for every 1000 pounds of industrial release, there was a corresponding 2.6% increase in autism rates (po.05) and a 3.7% increase associated with power plant emissions(Po.05). Distances to these sources were independent predictors after adjustment for relevant covariates.
Most vitamins are considered safe for up to two years past their expiration date (unless they contain mold), but may become less potent over time. Pregnant women and people in need of regular ...
The crash sent the taxi careening onto the sidewalk, where the vehicle hit the 51-year-old woman and two men, 44 and 49. The woman was “pinned” against a fence by the vehicle, a police source said
