Explain why it is generally warmer near the equator than it is near the poles.

Due to the amount of sunlight earth receives.

Explanation:

The earth is tilted in such a way that earth receives very less sunlight on the polar side.

In contrast to this the equator of the earth receives more sunlight so the regions lying at equator are warm.

This is the reason, why its warmer near equator and cold near poles. It is because of the angle of the earth which receives more amount of sunlight.

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
