There is less weight pressing down from above as the distance toward the surface decreases.
The pressure would decrease as you moved from the core to the crust.
If someone were to go deep enough into the Earth's crust, they would experience extreme heat and pressure. The temperature increases by about 30°C per kilometer, so it would become unbearably hot. The pressure would also increase rapidly due to the weight of the rock above, making it difficult to breathe and move.
Blood pressure would decrease
Yes it would. For instance in the breakdown of radio-active elements.
No. Fossils only exist in the crust. Any fossil subjected to the heat and pressure any deeper than the crust would be destroyed.
the deeper into earth crust the higher the pressure that forms metamorphic rocks
Constricting the afferent arteriole would decrease blood flow into the glomerulus, leading to a decrease in pressure within the glomerulus. This may result in a decrease in glomerular filtration rate and a reduction in the formation of urine.
Decrease
I would assume it would be igneous due to the massive amounts of magma in the earth's crust.
The earth's mantle would have formed initially in the same way as the crust, by the cooling of the earth but as for the metamorphic rock that defines the earth's mantle, that would have taken millions of years of extreme heat and pressure for it to form.
The pedosphere is where people live on the earth's crust.
An increase in blood pressure, blood volume, or permeability of the filtration barrier would increase net filtration pressure. On the other hand, a decrease in blood pressure, blood volume, or an increase in plasma protein concentration would decrease net filtration pressure.
