Question

Explain the phenomenon of seasonality experienced on earth

Answer 1

Answer:

Seasonal changes occur due to the tilt of the axis and the revolution

Depends whether its is facing the sun

Explanation:

Answer 2

Seasonality on earth:

• Seasons occur due to the tilt of earth’s rotational axis towards or away from the sun as the earth completes its revolution around the sun in an year long journey.
• This tilt of earth’s rotational axis is 23.5 degree relative to the ecliptic plane, which is an imaginary plane formed by the earth due to its revolution around the sun in almost-circular path .
• From around March 20 to September 20, Northern hemisphere tilts towards the sun thus experiencing summer season. While Southern Hemisphere remains away from the sun thus experiencing the winter season.
• Summer solstice: It occur around June 21, north hemisphere experience maximum tilt towards the sun while the southern hemisphere remains away from the sun. So, northern hemisphere receives the maximum amount of sunlight at this time.
• For other half year, Southern hemisphere tilts towards the sun thus experiencing summer season. While Northern Hemisphere remains away from the sun thus experiencing the winter season.
• Winter solstice: It occur around December 21, Southern hemisphere experience maximum tilt towards the sun while the Northern hemisphere remains away from the sun. So, Southern hemisphere receives the maximum amount of sunlight at this time.
• Equinox: Two equinox occurs when the sun is directly overhead at the equator. The south and north pole remains at equal distance from the sun. Thus, the resulting equal length of day and night. During the march equinox, northern hemisphere experience spring as the hours of day light increase while southern hemisphere experience autumn as days shorten. Opposite happens on the September equinox.
