It is absolutely true that China is seeking to lessen its dependence on coal by developing more hydro power resources. The correct option among all the options given in the question is the first option. China is blessed with natural rivers and it is slowly trying to reduce its dependence on coal powered plants to hydro power plants. This is also a great step towards reducing air pollution.
Answer:
B
Explanation:
Oceanic crust is the Earth's lithosphere's outermost layer located under the oceans and formed on the oceanic ridges at spreading centers that occur at divergent plate boundaries (ridge axis).
It is covered by a thin blanket of sediment that thickens away from the ridge axis.
Oceanic crust is different from the continental crust in numerous ways. For instance; It is younger, thinner, and denser than continental crust. Furthermore, It also has a different chemical composition.

Answer:
The evolution of karst landscape is by the interaction of water with limestone rocks.
Explanation:
- The karst topography is formed by the dissolved soluble rocks like the limestone and dolomite and featured by the sinkholes and caves.
- The development of the karst occurs when the acidic water starts to break down the surface bedrocks and cracks open in the bedding plane, as time passes these features gets wider and leads to the development of a drainage system. Carbonic acid is one of the main mechanisms for the formation of features.
- The karst landscape has a variety of small features and these include the sinkholes, limestone payments, cave pillars, stalactites, and stalagmites. Hazards associated with the karst landscape are erosion by rivers, sinkholes, and hollow holes and Karst wells, etc.
- The relations between the groundwater and surface water are water quality and quantity. The subsurface layer creates a filter and cleans water from other impurities.
