How hot is the continental crust? What are the layers of the Earth's crust? What is the pressure of the Earth's crust? Which atmospheric layer is closest to the Earth's crust? What is the temperature of the center of the Earth?
THE product of the rate of increase of temperature with depth in the earth's crust into the thermal conductivity of the surface rocks gives the rate of loss of heat from the interior. When allowance is made for the residual effects of the original heat, this gives a most important datum ...

41. Structure of the Land Areas. Experiment 40. —Take a copper ball having a ring just large enough to encircle it, the same apparatus as used in Experiment 19. (Fig. 22.) Place the ball within the ring and heat them both to a high temperature. Remove the ball from the ring and...
the temperature of which is but little above 100° C. The soil should be spread out as thin as possible. Allow it to remain in the oven for some time, until it is perfectly dry throughout. Weigh again. The loss of weight will be the weight of water contained in the soil. As there...
Three types of unequal stress on the Earth's crust are compression, tension, and shear. Stress arises because the fractured crust rides on a ductile mantle which slowly flows in convection currents. The plates of the crust collide in some places, pull ap
