1. At what location on earth do the stars rise in the west and set in the east? (1 mark) Explain how you arrived at this conclusion. (5 marks) 2. If the sun "moved" along the celestial equator instead...

Answer
Within the 9 meters range of south and North pole Stars rise in west and sets in east.
Generally if we are standing at the poles then the whole earth is revolving under our feet’s whether we are south
or North Pole then rise and set of stars will be affected because the spinning axis of the earth is far from the
actual geographic pole of the earth because of tilted axis. Generally at most of the portion of the earth stars rise
in east and sets in west but if we are very close to the poles of the earth stars go almost parallel to the horizon
ecause the whole earth is revolving under our feet’s and also tilted in its o
it. At some point when the parallel
moving star will go below the horizon, it will make very shallow angle and that will be east for us.

Answer
Seasons will not change like equinoxes and solstice will not be there (Neil F Comins, 2008).
The Seasons Are Linked to Equinoxes and Solstices (Neil F Comins, 2008)
Length of the day and night changed due to the movement or the earth around the sun position and inclination
of the earth in its o
it decides the length of the day and night on earth. Availability of sunlight on earth also
depends on the inclination and position of the earth in its o
it. Initially sun is in ecliptic o
it with respect to
the earth in which all equinoxes and solstice are presents as shown in the diagram. If sun starts moving along
the celestial sphere which is almost circular in shape then there will be no change in its distance with respect to
the earth hence there will no equinoxes and solstice on earth. Day light time will remain same on a particular
place throughout the year (Neil F Comins, 2008).

Answer
Snow line is considered as the asteroid belt existing between the mars and Jupiter. Planets lies left to the snow
line are considered as inner planets like earth, mars,venus,mercury while planets lies other side of the snow line
are called outer planets. Four differences between the Planets that lie on each side of a snow line are;
1. Planets on one side of snow line are Te
estrial like earth and mars which have a solid surface and
te
itorial properties like existence of mountains and craters while on other side are Jovian planet like
Jupiter and Saturn which consists of almost gases without any craters or te
estrial properties.
2. Planets on one side of snow line have solid surface like earth and mars while on other side have no solid
surface like Jupiter and Saturn are also called outer planets.
3. Inner planets which lies on one side of the snow line are rocky while on the other side of the snow line
are Gaseous Planets.
4. Inner planets like earth and mars have few moons like in case of earth we have only one moon while for
mars two but in case of planets other side of the snow line more than 5 moons exist like Jupiter and
Saturn have many moons.

Answer
We know that the Earth o
its around the sun in 365.25 days that means earth completes it one rotation in its
o
it around the sun in 365.25 days. Since the o
it of the earth is elliptical and earth also rotates on its own axis
so while revolting around the sun its angle with respect to sun changes on each passing day by an amount of
degree...
