Question

As Earth moves beyond the Northern Autumnal Equinox, the constancy of Earth's axial tilt causes the south pole to move closer to the sun, while the north pole moves further away. Days in the north become shorter while days in the south become longer. Likewise, the solar equator begins to move south. On Dec. 21M (the Northern Winter Solstice and the Southern Summer Solstice), the solar equator reaches latitude 23.5'S. On this day, day length is minimized in the northern hemisphere and maximized in the southern hemisphere. As Earth moves beyond the Northern Winter Solstice the solar equator move back towards Earth's equator, and days become longer in the north and shorter in the south. On March 21^st (the Northern Vernal Equinox and the Southern Autumnol Equinox), day length is equal to night length in both hemispheres. From your understanding of the Earth's axial tilt relative to the rotation around the sun, draw a line indicating the position of the solar equator during one annual cycle. As the solar equator waxes and wanes due to the axial tilt of Earth, solar radiation hitting Earth at varying latitudes is altered (Figure 8). Why does the amount of solar radiation hitting the equator (0') vary throughout the year? Why is the variation in solar radiation throughout the year greater for higher latitudes than lower latitudes?

Explanation / Answer

Ques-1:

Increasing elevation in latitude takes place from sea level at the foot of a tropical mountain to its summit, encounter ecological zones similar to the biomes found across great distances from the equator to the poles because intensity of sunlight varies on surface of Earth because of its curved shape. The amount of solar radiation hitting the equator (0) varies in waxes & wanes with the solar equator vary throughout the year because in tropical areas, the intensity of sunlight per unit area incidence varies compared to Polar Regions due to an oblique angle at higher altitudes.

Ques-2:

The variation in solar radiation throughout the year greater for higher latitudes than lower latitudes going from zone of equator to poles, intensity of variable solar radiation and every 1000 meters rise in elevation of latitude is leading to reduction in temperature of 6celcius degrees. Thereby more solar radiation observed predominantly at the equator region initiates a specific global way of air circulation and precipitation.
