Have you ever stopped to think about the ground beneath your feet? The part of Earth that we live on, called the Earth's crust, has more to it than meets the eye! Let's take a closer look at this layer of Earth that we call home. Related...
Temperature-dependent thermal diffusivity of the Earth's crust and implications for magmatism The thermal evolution of planetary crust and lithosphere is largely governed by the rate of heat transfer by conduction. The governing physical properties are thermal diffusivity (kappa) and conductivity (k = ...
Learn fascinating Earth's crust facts in this lesson, including the two types of Earth crust, its temperature, its thickness and the Earth's crust...
When compiling geoisothermal maps for the upper layers of the earth crust to depths about twice the erosion depth, the space-time regularities of temperature variation determined largely by the geographical latitude and elevation of the point under investigation must be taken into account. Some geo...
In this temperature range from 25 °C to 400 °C, Young's modulus of sandstone was reduced by 11 percent to a value of 31.04 GPa at 400 °C. However, a sharp drop in Young's modulus was observed at 600 °C, when it reduced to 15.62 GPa. When the thermal stress, resulted due ...
U–Pb ages were determined by split-stream LA-SF/MC-ICPMS in garnets from UHT granulite xenoliths (Star mine, South Africa; 124 Ma). They give a considerable age range of 400 million years with well-defined maximas at 3.09, 3.01 and 2.75 Ga. The oldest peak overlaps with the changeov...
Since laboratory synthesis of fullerenes requires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's crust at the time these naturally occurring fullerenes were formed. Which of the following, if...

The energy contained in rock within the earth’s crust represents a nearly unlimited energy source, but until recently commercial retrieval has been limited to underground hot water and/or steam recovery systems. These systems have been developed in areas of recent volcanic activity, where high rate...
The Department of Environment (DOE, 1993) of Bangladesh also suggested that sea-level rise may range from 30 to 50 cm by 2050. If sea level rises by 1 m along the coast of Bangladesh, cultivable land with an area of 1000 km2 will become a salt marsh (Cruz et al., 2007). Although...
