A year of documented learning ( MY LAST POST......E V E R )

Hello everybody this is my last post. I have had a lot of fun this year, especially because we got to use technology more then ever, and i liked that. It was a refreshing change from past years. Well here is my final post.... what my favorite part off each section we learned was!

Astronomy or The study of the moon, stars, and other objects in space was one of my favorite sections mainly because i learned so much. One of the things i leaned so much about was the sun but more mainly how it causes the seasons on earth. The seasons are caused not by how close the sun is to the earth at different times(which i used to think) but by where the more direct sunlight is on the earth. Earth rotates on its axis, plus it is at a 45% angle so that means different parts of earth get more or less direct sunlight causing seasons.

My favorite part of the Weather and Climate book was the layers of the atmophere. I knew that earths atmosphere had layers i just didn't know what they were. They are : The troposphere ,the troposphere is the layer of the atmosphere in which Earth’s weather occurs. The stratosphere. The stratosphere is the second layer of the atmosphere and contains the ozone layer. The mesosphere, the mesosphere is the layer of the atmosphere that protects Earth’s surface from being hit by most meteoroid. And the thermosphere. The outermost layer of Earth’s atmosphere is the thermosphere.

Another one of my favorite sections was geology. More specifically plate tectonics or The theory that pieces of Earths lithosphere are in constant motion, driven by convection currents in the mantle. I thought this was really interesting because it explained why earth quakes happen. Earth quakes are just two of the plates rubbing up against each other. Also a volcano or a weak spot in the crust where molten material, or magma, comes to the surface is also explained by plate tectonics.

Weathering and Erosion was a very interesting topic. I especially liked the erosion part of it. More specifically wind erosion. Wind erosion has two parts; Deflation and Abrasion. Deflation is the process by which wind removes surface materials. When wind blows over the land, it picks up small particles of rock and sand . Abrasion is The grinding away of rock by other rock particles carried in water, ice, or wind. So it basically polishes rock away with other rock constantly hitting it.

OK finally, our latest book Earth's Waters. In earth waters we learned how water got to our houses from underground or in the air. From underground, i found out that water can come from aquifers or an underground layer of rock or sediment that holds water. There is also a artisan well or a well in which water rises because of pressure within the aquifer. We can also get our water from above ground in lakes our ponds. We even make reservoirs or A lake that stores water for human use. From these sources it goes to a pipe system to a treating plant here it gets treated This is the treatment process. We also learned the process how water goes in a cycle to precipitate and evaporate called the water cycle.

Well That was my final post it was a great year, with lots of fun and laughs. I sure will miss it. Well this is Larry, signing off F O R E V E R

This is a good song for the end of the year
