What is the MOST important factor in the changing of the seasons?

Chemistry
1 answer:
slava [35]2 years ago
6 0

Answer:

A. the earth’s tilt toward the sun

Explanation:

The most important factor in the changing of the seasons on the earth is the earth's tilt towards the sun.

This causes the differences in the amount of insolation which is incident on the earth surface. Throughout the year, as the earth continues to spin, it receives different amount of solar radiation all year round.

The sun is always overhead around the equator. Such regions of the world receives direct insolation and are mostly constrained to a wet and dry season.

Areas above the equator have the sun at an angle. The diffused sunlight present distinct seasons all year round.

Describe the shapes and relative energies of the SPD & f atomic orbitals
Deffense [45]

Explanation:

The shapes and relative energies of the orbitals s,p,d and f orbitals are given by the principal quantum number and the azimuthal quantum number.

The principal quantum number gives the main energy level and the azimuthal quantum number denotes the shape of the orbitals.

  • For the principal quantum number, they represent the energy levels in which the orbital is located or the average distance of the orbital from the nucleus. It takes the number n = 1,2,3,4,5,6,7......
  • The azimuthal quantum number(L) shows the shape of the orbitals in subshells accommodating electrons. The number of possible shapes is limited by the the principal quantum number.

Wind : swirls :: chemical bond : ___________.
drek231 [11]
Options are as follow,

1)  Flashes
2)  Skips
3)  Stretches
<span>4)  Jumps
</span>
Answer:
            Option-3 (stretches) is the correct answer.

Explanation:
                    The best analogy which suits a chemical bond is the stretching of chemical bonds. Remaining verbs doesn't explain the property of chemical bond. For example, the chemical bonds did not flashes, neither they skip or jump.
                    The chemical bonds can stretch and bend. As predicted from IR spectroscopy, different bonds can stretch and bend at different energies. The stretching of bonds require more energy while, bending of bonds require less energy.
