Question
There are about the same number of lunar eclipses and solar eclipses in a given period (224 solar eclipses and 230 lunar eclipses in the 21st century, for instance). Therefore, we are equally likely to observe either type of eclipses from Berkeley.[NB: let's pretend that the weather is always favorable even though this is far from true!] 4. a. True b. False 5. The observed location of planets around their parent star does not necessarily indicate where they originally formed. a. True b. False 6. The Earth's surface spins as a solid body, i.e, all points on the surface of the planet execute one revolution around the planet's axis in the exact same amount of time (just under 24h, a sidereal day). Therefore the length of time between sunrise and sunset is the same at all points on the planet. a. True b. False
Explanation / Answer
4. B . False
Eclipses generally repeat themeselves after a time period called as Saros cycle which is equivalent to 18 years, 11 hours and 8 hours. So they cannot be similar and have same number of solar eclipses and lunar eclipses for any other time period like a centuary or so.
5. B False.
If any planet is hit by a meteroid it changes it's postition. Eg: Earth after being hit by a meteroid had changed it's path many years ago.
6: False
It is true that earth's surface spins as a solid body, but as earth's axis is slightly tilted, the areas at poles wont recieve sunlight for 6 months and would continue to recieve for next 6 months. But at equitorial regions they a different sunrise and sunet time periods.
