relative timeGeologic time scales is very important concept for understanding earth system events such as global climate change. However, understanding of geologic time scale in a relationship with human history is very difficult because of relatively short period of human existence in earth history. ...
A. One part is understanding Earth's history: the big picture. The time periods I'm looking at are not that far back geologically, about 15 million years. The Earth looked very different then. There were forests in places where there are savannahs today. The poles were much warmer; there...
The modern era is known in large part for this kind of change, where tasks that used to be performed on a very small scale can be done in far less time. Look around you, wherever you are right now, and you'll probably find many objects that are mass-produced or created using some ...
Fig. 2. A) Geologic map of the Criner Hills area in which the MCQ is located. The MCQ is marked using a rectangle (lower right of the geologic map) and is the primary focus of this study (Frederickson, 1957). Anticline and fault locations are marked. Oklahoma map shows the location ...
Quantifying the spatiotemporal characteristics of government support for rural development is crucial for accurately optimizing or formulating policies for rural development, but research identifying government support for rural development at the geospa
This finding is qualitatively consistent with laboratory observations of sliding between saturated rocks at both transient and steady-state pore pressure conditions38,39,40, and may explain field observations of triggered and induced seismicity from subsurface operations in different geologic settings1,11,...
surface if benzene crystals were subjected to pressures during impact or burial59 and/or subjected to higher pressures; the non-recoverability after pressure removal, as shown in the experiment, would be of interest if materials at depth were eventually exposed (via geologic uplift60) onto the ...
The raised peneplain theory is admittedly problematic because it requires (among other conditions) large magnitudes of vertical uplift occurring over a short time interval during the recent geologic past—an extreme process that can only be achieved under a restricted range of lithospheric conditions (...
A concept of deep time requires the ability to sequence events on an immense temporal scale (succession) and to judge the durations of geologic processes based on the rates at which they occur. The twin concepts of succession and duration are the same ideas that underlie a concept of ...
There is a certitude that the mineralization ofCO2will in fact provide "geologic interval" sequestration. (gratuitous commentary alert..) Also, on a personal level, I find this to be an exemplification of the (to me) apparent fact that "what we are for" on this planet, is to "help out...
