As part of the greenhouse effect, Earth’s surface radiates heat back into the atmosphere and the atmosphere absorbs this heat. Why do areas near the equator generally radiate more energy back into the atmosphere than areas near the poles? Areas near the equator have more clouds in the atmosphere than areas near the poles.
Areas near the equator receive more incoming solar energy than areas near the poles.
The greenhouse effect only occurs near the equator.
The greenhouse effect only occurs near the poles.

Because greenhouse gas molecules radiate heat in all directions, some of it spreads downward and ultimately comes back into contact with the Earth’s surface, where it is absorbed. The temperature of the surface becomes warmer than it would be if it were heated only by direct solar heating.

The correct answer is B. Areas near the equator receive more incoming solar energy than areas near the poles.

Explanation:

The equator is located in the center of the planet from North to South, this location cause this zone and nearby zones to receiver more solar energy than areas near the poles. This occurs because the natural tilt of Earth makes sun rays directly hit the equator all the time of the year, while areas in the poles are not hit directly and the exposition to sunlight varies with the seasons of the years. This explains why in the equator the temperatures are higher than in the poles. Besides this, the difference in radiation received makes areas in the equator radiate more energy back due to global warming gases, and the global warming phenomenon.

the correct answer is c   with the systems

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.
