What must happen for most areas on Earth to experience all four seasons?

To experience all four seasons for most areas on Earth, the angle between the sunlght coming from the sun and how that sunlight hits the surface of the earth, must be different.

Explanation:

The angle towards the sun must be different. What I mean is the angle between the sunlght coming from the sun, and how that sunlight hits the surface of the earth, must be different.

In the summer that angle is the biggest ( on the equatotor is is exactly 90 degrees). In winter that angle is much less then 90 degrees In winter you hsve the steapest angle of all four seasons.

So, to experience all four seasons, the angle between the sunlght coming from the sun and how that sunlight hits the surface of the earth, must be different.

EXTRA:

When the sun Rays, hit the surface of Earth in the summer, the incoming solar radiation is really 'dence' in comparison to the winter. That is due to that angle between the sunlght coming from the sun, and how that sunlight hits the surface of the earth.

The bigger surface area is a result of strap angle

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
