Which areas natural resources are least likely to be able to support a high population density?

1 answer:

5 0

True, the answer is b desert. All other choices can support certain organisms, unlike a desert. Most rich biodiversities are found in places where there is water. Water is one essential factor in the world that helps support life. River floodplain, delta, and valleys have this element that makes this area rich habitats.

In nuclear fission and fusion reactions mass is converted into energy. The average person in US uses around 100,000,000 J of ene

daser333 [38]

Answer:

a) The yearly energy consumption for a US population of 300 million is $3\times 10^{16} J/year$

b) The energy that would be released if a 60 kg person were converted entirely into energy is $5.4\times 10^{18}$ Joules.

c) 180 years would this amount of energy support a population of 300 million.

Explanation:

a) Average energy consumed by single person of US = 100,000,000 J/year

Then 300 million US citizen will consume:

300 million = 300 × 1,000,000 = $3\times 10^8$

The yearly energy consumption for a US population :

$100,000,000 J/year\times 3\times 10^8=3\times 10^{16} J/year$

The yearly energy consumption for a US population of 300 million is $3\times 10^{16} J/year$

b) $E = m\times c^2$

E = Energy from converted mass of m

c = speed of light

Given mass of person = m = 60 kg

$E=60 kg\times (3\times 10^8 m/s)^2 = 5.4\times 10^{18} J$

c) Energy calculated in part (b) = $E=5.4\times 10^{18} J$

The yearly energy consumption for a US population of 300 million in an year = $3\times 10^{16} J/year$

Let the that would be supported by $5.4\times 10^{18}$ Joules of energy be x.

$x\times 3\times 10^{16} J/year=5.4\times 10^{18} J$

$x=\frac{5.4\times 10^{18} J}{3\times 10^{16} J/year}=180 years$

180 years would this amount of energy support a population of 300 million.

The greatest human impact on the carbon cycle has been through ____________.

Ipatiy [6.2K]

The correct answer is C. The burning of fossil fuels.

Explanation

The carbon cycle is a cycle in which carbon interacts with the biosphere, the lithosphere, the hydrosphere, and the Earth's atmosphere. Knowledge about this carbon circulation makes it possible to appreciate human intervention in the climate and its effects on climate change. This cycle makes life on Earth possible because the plants consume carbon dioxide, however, the balance of this cycle has been altered by the massive use of fossil fuels such as oil, gasoline, and gas. This alteration causes the atmosphere to deteriorate causing the sun's rays to directly penetrate the earth, on the other hand, it causes the greenhouse effect to increase, causing the earth's temperature to rise. So, the correct answer is C. The Burning of fossil fuels.
