b. it moves around earth
it has different phase because it orbit and move around the earth
Attached in this answer is the carefully crafted phase change diagram of water.
Since there are many states of matter (3 of which are the most discussed - solid, liquid, and gas), a substance can transition from one phase to another by the input or removal of energy. Matter in its solid state has generally lower energy level compared to that in liquid state. Then matter in liquid state similarly has lower energy level compared to that in its gaseous state.
In the example of water, if we assume that solid water (ice) is initially at a temperature below 0 degrees celsius (let's say -5 degrees Celsius). This would be Point A in the diagram.
If we put the ice on a hot plate, the ice receives energy and starts heating up until it reaches the melting point of ice (at 0 degree Celsius) found at point B. At this point, since the hot plate is still on, the ice keeps receiving energy from the heater as it slowly transitions into a liquid while the temperature remains constant until it is completely liquid (at point C, still at 0 degree celsius). Then the liquid water is still being heated and its temperature now rises up to 100 degrees celsius (point D), now called boiling point of water. In this case, water starts to boil and some molecules turn into a vapor (this is the more accurate term as opposed to gas). Continuous heating will completely turn all of liquid water into a vapor (point E) and then as the heater keeps heating the vapor (assuming that the sample is contained in an airtight vessel), the temperature of the vapor rises up until it reaches 130 degrees (point F).

because of the rotation of the moon on its own way in the earth sometimes causing some alignment of the earth,moon and sun that is lunar eclipse and solar eclipse
4. Surface Runoff
5. Ground Water
Explanation:The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. ... As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5)
I can't illustrate it for you but I can give the meaning :)
New moon-The dark side of the moon is facing
Waxing Crescent Moon-We see only a small portion of the lighted side of the moon
First Quarter-We see half of the lighted side of the moon
Waxing Gibbous Moon- The visible lighted side of the moon is now bigger than half of the lighted side.Gibbous means "having a hump"or"humpbacked"
Full Moon-At this time,Earth is between the moon and the sun.So,at an angle,we can see the entire lighted side of the moon
Waning Gibbous Moon-The visible lighted side of the moon is somewhat smaller than the full moon.
Last Quarter Moon-We again see half of the lighted side of the moon.
Waning Crescent Moon-We again see only a small portion of the lighted side of the moon
The phases of the moon are the different ways of the moon looks from earth over about a month. The phases occurs because the sun lights different parts of the moon as the moon revolves around the earth.
a. its move around the sun
b. it moves around...
