The earth is tilted on an axis (Round about the 23.4 DEGREE mark) and this causes differences in the amount of sunlight that reaches any given area and so results in differet climatic conditions in different parts of the world.
The movement of the earth around the sun as well as the tilt of the earth causes Autumn and the rest of the seasons. In Autumn (Fall, in the US) that part of the earth is beginning to move away from directly facing the sun.
Summer!
By erosion.
Sunshine will be avail to one part of the earth and other part would be dark.
My guess is that, Its winter in US when the earth is tilted south to the sun.
Tilted away, the nights would be longer and the days shorter. Such a time would be the winter season.
No, Earth and the other planets and debris are part of the sun's solar system.
The sun never moves, it is the Earth that moves. Climate change depends on that part of the Earth's relative position to the sun.
Indeed, she is a part of Disney's Friends For Change.
Since the Earth's temperature changes, the study of that will be part of Earth Science. But there are lots and lots of other things about the earth, besides temperature, that is part of Earth Science. Also, other things besides the Earth change temperature ,so many other kinds of science, besides Earth Science, study the effects of temperature .
In winter, the part of Earth is not facing the Sun so it makes that season we have in North America cold. In summer, that part of Earth is facing the Sun which makes it hot. Spring and Fall are seasons that nearly faces all the Sun.
the different shapes are called phases and they change as the moon moves round the earth and therefore changes the distance from the sun so the dark part is the shadow of the moon and the part you can see is the part in the sunlight.Additional answerThe moon doesn't actually change shape. You may be asking why it sometimes looks round, at other times, crescent shaped. It's not changed shape, it's that you can only see part of it, and different parts at different times. When the position of the moon, earth and sun are such that they are in that order, the whole side of the moon that's towards the earth is lit by the sun and we see it as a round shape. But usually the earth is not exactly in between the moon and the sun, but a bit offset. We then see part of the moon that's not lit as well as part that is. The part that is varies in its apparent shape depending on just how much of it we can see. If most of what we can see is unlit, the lit bit looks like a slim crescent.Also, the phases do not change as the moon moves round the earth but how its relationship with the sun and earth changes
