Question

Give a geographical reason for each of he following
1) the sunset and sun rise occured at a different time at different places
2)the earth is not a perfect sphere
3) Venus is hotter than mercury

Answer 1

1. As due to the rotation and curvature of the earth, the sun is seen at diff times and diff places
2. Because of the Centrifugal force exerted during rotation
3. Because CO2 in its atmosphere traps the suns hear

Answer 2

1. Because of the Earth's tilt on its axis, the path of the Sun across the sky varies, and therefore, the rising and setting time changes. At different locations on Earth, the rising and setting times vary because the portion of the celestial sphere visible from different locations of Earth is different.

2.It is because, it is an oblate spheroid. This means flatter at poles and bulged at equator. This is due to the anomalous centrifugal force on earth, from equator to pole.

3. Venus is hotter than Mercury because it has a much thicker atmosphere. The atmosphere, the gaseous layer surrounding a planet, is like a blanket. ... Venus on the other hand with it's much thicker atmosphere holds all the heat it gets. The heat the atmosphere traps is called the greenhouse effect.
