Answer:
B
Explanation:
The rocks' forms and edges are smooth and appear to have been rounded. This is a hallmark of abrasion because the rocks lose their sharp edges and round out as a result of the constant rubbing and scraping action of wind-borne particles against them.
B. It is readily available in most places.
C. It produces net-zero emissions.
D. It is biodegradable
Answer:
A. It requires mass production of crops.
Explanation:
Of all the options the only one that represents a disadvantage is that biopower requires mass production of crops because it could cause loss of biodiversity, degradation of soil quality, soil erosion, food toxicity (due to pesticide residues) and pollution ( use of fossil fuels for agrichemical manufacture, farm machinery and long-distance distribution).
The fact that it is readily available in most places, produces net-zero emissions and is biodegradable are all advantages.
I hope you find this information useful and interesting! Good luck!

Answer:
its shadow usually misses Earth
It is known as sleep apena
Answer:
The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.
B. Oceanic crust is denser than continental crust.
C. Oceanic crust is less dense than continental crust.
D. Oceanic crust is older than continental crust.
Answer:
B.) Oceanic crust is denser than continental crust.
Explanation:
Oceanic crust is denser, so it is subducted under the continental crust. The less dense magma then rises up through the continental crust, then it's further increasing the size of the continental crust and then maintaining it's lower density than the oceanic crust, which then causes subduction.
I hope this helped. I am sorry if you get this wrong.
