Is there any answers cause that sounds like a multiple choice
Answer:
Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH < 3.5) and very strongly alkaline soils (pH > 9) are rare.[2][3]
Answer:
Option (C)
Explanation:
The lithosphere is the hard, outermost portion of the earth. They are very brittle in nature as the rocks are deposited in this region. The rocks here breaks due to deformation. The lithosphere is comprised of numerous small and large plates. They are of 2 types, and they are the oceanic crust and the continental crust.
According to the plate tectonic theory, these plates continuously floats over the less dense asthenosphere layer because of the convection current that forms in the mantle. This current generates due to the heat radiated from the core of the earth.
The asthenosphere is the layer just below then lithosphere and here the rocks are solid in nature but they have the ability to flow in response to deformation.
Thus, the lithosphere as a whole moves due to the convection current.
Hence, the correct answer is option (C).

Answer:
As economies advance, they require more energy. Given today's focus on greenhouse gases, coal usage will decrease. Natural gas is plentiful and is easily used for heat and as a feedstock for chemical production. Petroleum is also readily available and can be converted to energy and chemicals.
Explanation: All three resources are transportable and sources are located across the globe. However they require transportation to areas which don't have ready access. This requires roads, railways, pipelines and ships.
