Question

#2 & #3

Compare and contrast the following two scenarios in terms of the effect on the subsolar point at the equinoxes and solstices: What would happen if the earth were tilted at 35 degrees? What would happen if the earth were not tilted at all? Consider also the effect of each scenario on the circle of illumination throughout the year. Consider the following scenario: Eduardo is standing at 22 degrees south and it is noon sun time. Compare and contrast the apparent direction of his shadow on the equinoxes and solstices. At noon sun time, is there any day of the year on which Eduardo would appear to have no shadow at all? Approximately what time of year would this occur? Compare and contrast two samples of air in terms of the sample's composition, temperature profile and function: Sample A, taken 2 km from the surface of the earth, and sample B, taken at 32 km.

Explanation / Answer

2) On equinox Eduardo' shadow will be exactly same as his height because on equinox every part of earth receives the equal day and night. On summer solstice his shadow will be much more geater that his height because the inclined radiation of sun and also at winter solstice his shadow is much more shorter than his height because sun will be overheaded to him . His shadow become to short to be visible on approximately 20 or 21 December every year.
