If there was no gravity the rocks will have no where to drop off because gravity is what holds down everything, so there would be no build up of land.
Tectonic plates, although rigid, also move. And they move in rebound, because of the tremendous heat that comes out of the interior of our planet, which burns at 6.7500º C, almost like the sun. This fiery heat moves the mantle and consequently expands into the lithosphere and Earth's crust.
Answer:
Shifting cultivation is not included in commercial farming.
Explanation:
There are multiple types of farming, and that is prevailing more and more is commercial farming. This type of farming is characterized by large-scale production, with higher amounts produced in a smaller area, new types of high productivity seeds, use a lot of pesticides, being heavily mechanized, etc. The reason why this type of farming has developed and is becoming dominant is that there has been an exponential rise in food demand because of the growing global population and increase in consumption per capita.
Something that is not used in commercial farming is the shifting cultivation method. This method basically means that every season a new type of crop is planted, thus leaving the soil to recover naturally and restore nutrients needed for when the initial crops are planted again. The commercial farming doesn't use this method because it simply relies on using high amounts of fertilizers, so every season that soil is enriched with nutrients.
Answer:
superincumbent load in rock slab
Explanation:
- This pressure is defined as the geothermal pressure that the rocks excerpt from above the surface of the earth which is caused by the weighting of the overlying rock strata.
- This identification can be found in geology itself in terms of fluids and natural gases which led to the formation of coal deposits millions of years ago. With great pressure and thrust from the rocks
- This burning pressure that the rocks feel from above as in the case of earth core and mantle layers. A tectonic plate is subdued to greater depths here and this layer and hence more pressure from the remaining earth mass from above.
