In our class we are learning about glacier. on our feildtrip we went sydney boulder.  sydney boulder is a glacier that moved from canada. Glacier are  hudge peices of ice that move over the land. they are really big in size. they mostly form in polar region.

99%of glacier ice are pack in big icesheets. they are on every continent expt in austrailia. glacer ice  has the largest ponds of fresshwater. Alot of glacier store water, and provide water to plates. At the troprics glacier form in the moutains.

The reason why I pick glacier is because they are really big in size. one fact i found interesting is that 99% of g;acier ice are big ice sheets

In oceanograghy so far we learned about lots of things; sediments, ocean tides, etc. But the one that intrigued me the most was the Glacial Activity we did during the field trip last Friday. It was very interesting to learn about it, as long as eratics, etc.

Glacials are made during Glacial periods; an intervak of time during an ice age marked by cold temperatures. Glacials are made when cold temperatures freeze the ice, and form a big “ice cube”. Glacials were very common during ice ages. The Glacials picked up sediments and collected them over a period of time.

After the ice age, the Glacials that picked up a lot of sediments turned into a rock which is living proof of glacials. Eratics are another name for Glacials as well. Which means they are erratic.

On the field trip we stopped by an erratic that was located in my home town, Groveland. It is a large four sided erratic, that is approximaently 25ft tall. It is said to be an awesome place to pratice rock climbing.

However, the erratic, Stickneys boulder wasnt always located in Groveland, MA. It traveled all the way from Canada. That means, during the ice age, the glacial started in canda and along the way picked up sedimetns and ended up as a awesome erratic that landed in Groveland.

I found this to be the most interesting thing i have learned so far in Oceanography because it was neat to learn about Glacials that turn into erratics. Also, because its fascinating to have something that was originally formed during the ice age still stand today. It took my interest because it is neat because it is in my hometown, and marks a part of history that i knew little about. After learning about Glacials, and Stickneys boulders I learned a little information that i didnt know before!

On our field trip we saw a lot of glacial features. One even in our hometown. Many of theses glacial features were very interesting, especially the one in haverhill in the woods was very interesting. g
