How did the use of groundwater change from preindustrial times to industrial times?
a. groundwater use decreased from preindustrial times to industrial times.
b. groundwater use increased from preindustrial times to industrial times.
c. groundwater use remained virtually the same from preindustrial to industrial times. d.groundwater was not used during preindustrial times.

The correct answer is option b.

Explanation:

The water sources, which are found underneath the ground in sand, rocks, and soils is known as the groundwater. The amount of groundwater, which was used at the time of the pre-industrial period was very small in comparison to the amount used at the time of industrial times.  

This has resulted in a substantial reduction in the concentration of groundwater available at the present time. Other elements, which had resulted in a decline in the level of groundwater comprise a lack of precipitation and an increase in the rate of pollution.  

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
