Answer: The porous nature of the rock bodies makes them good reservoirs of these fuels.
Explanation:
Oil and natural gases most times occur in porous rocks. These rocks are usually sedimentary rocks like sandstone and limestone. There are three(3) major classes of sedimentary rocks and they are: Clastic sedimentary rock
Carbonate sedimentary rock
Evaporitic sedimentary rock
Clastic rocks are the rocks that are gotten when sediment particles are broken down from formerly existing rocks via processes like rainfall, wind movement, freezing etc, accumulates and cements together.
When the old parent rock is weathered or broken down, the particles and sediments are carried via water from the streams and rivers until they get to another destination where they gather togther and solidify overtime to form sedimentary rocks.
Mud solidifies to become shale which can also be called mudstone.
Sands are cemented via silica or another substance called calcite to form sandstones.
Gravels develop into conglomerates.
Sandstones due to its very inherent porosity found in between the grains become excellent reservoirs for oil and natural gas.
The type of rock that is shown above is sedimentary.
Answer:
c. Lack of food sources
Explanation:
The groundwater has been used more and more around the world. There are large reserves of it, but in the past few decades the groundwater reserves have constantly been going down. The main reason for this is the lack of food sources. Because the global population is constantly on the rise, more and more food is needed, and in order to produce it, more and more farmlands are created. The increased number of farmlands means that more water is needed for irrigation, thus the groundwater reserves are the ones that suffer the most.
Answer:
Mafic minerals are usually dark in color and have relatively high specific gravities (greater than 3.0). ... Felsic minerals are usually light in color and have specific gravities less than 3.0. Common felsic minerals include quartz, muscovite mica, and the orthoclase feldspars.
Pretty sure its called the 38th Parallel, or the Demilitarized Zone. :)
