Transforming the HIPPARCOS trend results of Gross and Vondrák (1999) to a hotspot reference frame, they find that during the past century the linear trend in the path of the pole relative to hotspots was 4.03 mas yr−1 towards 68.4 °W longitude, or about 15% faster and in a more ...
You may feel like you're standing still, but you're constantly moving — fast. Depending on where you are on the globe, you could be spinning with the planet at just over 1,000 miles per hour, according toSpace.com. People on the equator move the fastest, while someone standing on th...
Subduction zones have recurrently formed on Earth. Previous studies have, however, suggested that they are unlikely to start in the interior of a pristine ocean. Instead, they seem to be more likely to form from another pre-existing subduction zone. One
The aforementioned Zhu et al. study performed a factor analysis to determine the causes. According to the paper, Factorial simulations with multiple global ecosystem models suggest that CO2fertilization effects explain 70% of the observed greening trend, followed by nitrogen deposition (9%), climate ...
句中that引导宾语从句1,000 times faster是倍数的表示方法。If a sixth mass extinction occurs, scientists who havestudied the issue believe that up to three quarters of allspecies on Earth could die out. Of course, as we humansdepend on so many species for our survival, we wouldalso be at ...
Denser, faster, or larger objects will have higher yields (with linear, square, and cube scaling, respectively). Because of the power-law size distribution of NEOs, low-altitude airbursts are far more likely hazards than crater-forming impacts and are therefore of intense interest to the ...
This happens naturally due to their horizontal separation rates until the separation grows to one half the orbit circumference, after which the separation starts to decrease again as the faster moving satellite approaches and then “laps” the slower one. (There is minimal danger of collision ...
The wind is called “superrotation” because it is sixty times faster than the winds at ground level on Venus. The speed of the zonal westward wind increases with altitude and reaches ~ 100 m/s (mean value) near the cloud top altitude (Khatuntsev et al. 2013; Hueso et al. 2015). ...
wet mixing the concrete in a mixer or wheel barrow and pouring it in the hole. This type of technique and other time savers is how they can build faster and cheaper than we can. We have always been skeptical of dry setting fence post piers, but never had directly compared the two ...
The GS generated during such crossings are likely to recover at a faster rate during their recovery phase, as compared to the GS generated during intermediate or near-end crossings.doi:10.1007/s10509-019-3560-xBadruddinKumar, A.Derouich, M....
