What does an object break up due to gravity in intitle forces as it approaches a planet

It passes the Roche limit a break due tidal force.

Explanation:

The name Roche limit is due to famous scientist Edouard Roche.  It is known as the minimum distance which is smaller object can exist and as a body held together by itself gravity. Roche limit is also called Roche Radius.

Its minimum distance is from the center of the planet. For formation it allows the material to come together. The example is large enough moon.  

carbon atoms, hydrogen, oxygen, and nitrogen.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
