We  learend  about seasons and how we have seasons.  becuse we have have axis is tilted and itc creats sesons.    the seasons are  summer ,  atom, winter and spring. we also have day and night.Becouse the earth rotats on axis . The sun rises the earth and sets in the west.

# data[].attributes.body
We have seasons because the  earth orbits around the sun. The earth orbit and makes one side of the earth closer to the sun. If the northern axis is facing the sun the norther would be summer and the southern would be winter.

The reasons why we have seasons is that  when the axis is tilted it crates seasons . season-summer-atom-winter-spring.

We have seasons because, earths tilt+orbit=seasons is why we have seasons

# data[].attributes.body
because the orbit around the sun. the sun shines on the side that is facing the sun.when the earth spins i t will hit that side . in march we have the vernal equinox. in June we have summer solstice. autumnal equinox. December we have the winter solstice.

# data[].attributes.headline
We learned how the Earth rotates. When the Earth is facing the sun, it's daytime but when the Earth is not facing the sun it's nighttime. Seasons happens by the orbit around the sun. The seasons are: summer, autumn, winter, and spring.

# data[].attributes.body
we learned how the earth rotates at an angle to create day and night wen one side of earth is facing the sun it is day time the other side is night we have seasons becuse the earth orbits around the supo creat winter summer fall and spring

# data[].attributes.body
We learned that Earth  has seasons because  our planets axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane -the plan of earths orbit around the sun.

StarChild Question of the Month for March 2001

Question:

Why is there day and night?

Answer:

Clearly, when you see the Sun shining in the sky, it is day, and when you don't it is night. So the real question is "why is the Sun in the sky at some times and not at others?" We can see that the Sun seems to move across the sky starting in the east in the morning, moving toward the south at noon, and then toward the west as the day ends. How does this happen?

Long ago, people believed many weird things about the Sun and how it traveled across the sky. The ancient Greeks believed that the Sun rode across the sky in a chariot drawn by four white horses driven by the god Heleius! These days, we know that the Sun appears to move across the sky because the Earth rotates on its axis.

So how does the turning of the Earth lead to the Sun's motion across the sky? It is easy to see this if you shine a bright light on the side of a globe in a darkened room. Find where you live on the globe. Now slowly spin the globe on its axis so that if you look down on the north pole, it is rotating counterclockwise. Watch what happens to the place where you live. Do you see that it is sometimes pointed toward the light (which represents the Sun) and sometimes away from the light? Hey, you've made day and night!

When where you are is pointed toward the Sun, it is day. Then the Earth rotates you away from the Sun, and it is night.

Think about this!

So, how fast does the Earth have to rotate in order to make one complete spin in 24 hours? At the equator, the Earth is rotating at a speed of about about 2200 kilometers per hour. Good thing we human beings can't feel this motion!

Day and night have a major effect on earth. My first piece of evidence is Rebecca Kaplan said " So when the sun is shining on the earth it warms up, after the sun sets it has time to cool down. So in...

space,Mercury,Veanes ,Earth,Mars are tresaroreal planets and jupider and saturn are gas giants and jovin planets and urnas and neptun are are ice giant and their also jovin planets.:)
