This year when we learned about astronomy i had a great time. I learned many interesting facts about the outer world that i didn't know before. But my favorite thing was about the moon. I knew the moon had phases but what i didn't know as what those phases caused and how they worked. Like when its in the right position with the sun and Earth it can cause an eclipse. Or how it rotates around Earth making it night and day.
The climate and weather control was another thing we learned this year. This one i wasn't to interested in but i still had a favorite. The warm and cold fronts. I was interested in these because i thought it was cool to know what really caused the weather patterns in our general area. And how a one front can take over another front causing it to be either warm or cold.
Geology is something i have learned many times in my life so i kinda knew some of the stuff that we were going to learn about. But in all my favorite thing about geology is learning about Earths crust. I think it is awesome to know that the land we stand on is moving very slowly on top of lava. Our crust was one all together in one big continent called Pangaea. But now it is all over the place. and one day many years from now it will be totally changed once again.
Weathering and erosion is something that happens every day. Weather it is from rain, snow, or wind. but the best thing i learned about this is that erosion is a huge factor that changes our planet everyday. Erosion can break down rocks and flatten mountains over the course of time. One day when we're all gone most of the mountains around us will be flattened down to nothing. I just think its interesting that something so weak can take away something so huge in just a matter of time
The final thing we learned this year was Earths waters. Earths waters are made up of oceans, lakes, rivers, ponds, and streams. They spread throughout the planet in all different sizes. But the coolest thing i have learned about them is that they are slowly decreasing. Now its not cool that our water is being depleted but its interesting that something SO huge like an ocean is slowly being taken away by time.
