That’s an Iceberg’s Mother Hello reader, today you are going to learn about and iceberg’s mother. I won’t tell you what it is, but if you keep on reading you’ll find out. Now, as I said earlier I am going to tell you what is an iceberg’s mother. It is a giant blue and white ice sheet covered in layers of snow and ice with rocks. It is called a glacier Where are glaciers, you ask? If you know where icebergs are you should know where glaciers are but if you don’t know where icebergs are I will tell you. Glaciers are in laces cold all year long. For example, Antarctica, Alaska, and Greenland. A glacier moves but it moves really slow. Slower then a snail. For example 30 cm. per day. Sometimes they can move as fast of 10 inches per day. That’s still slower then a snail. It usually flows down a hill but when the hill ends the glacier flows into the cold blue sea. Now I am going to warn you about something dangerous. If you ever go on a glacier and see a big crack don’t jump into it because if you jump into into will die and your body will fall down to the deep brittle ice which is the center of a glacier. The giant crack in a glacier is called a crevasse. Ok, now you are going to learn about the parts. What parts you ask? The parts of a glacier of course. The first part is a horn. Not like a unicorn horn. It is the tippy top of a tall glacier. Now lets go down to the cirque. It is bowl. Not like a bowl you eat out of but it is a bowl shaped hollow place near the base of the mountain. Now, lets go even farther down to the moraines. A moraine is a ridge of rocks that have been picked by a glacier. ok now that we are done with the parts of a amazing glacier lets move on to the next thing which is how are glaciers. To be continued…………
That’s One Big Snowball A glacier is like a big frozen white snowball because they are both made from snow and ice but if you want to know how the snow and ice make a glacier you have to keep on to find out or else a giant 8,000,000,000,000 pound snowball will run you over. Today reader you are going to learn about how a gigantic glacier is formed in the following steps. Heavy snow falls, then more heavy snow falls, the more heavy snow falls till it forms a big pile. The heavy snow becomes round and turns into grains of ice with air bubbles. Then more heavy snow falls and weighs down the air bubbles and forces out the air and the ice becomes blue The pile of snow and ice gets heavy and it begins to move. That’s is when it is called a glacier. All if those kind of short steps don’t seem to take a long time but it does. It takes many years. In those cold years a firn happens. A firn is when snow falls for years and the snow is compacted down by the weight of the snow. Now a big glacier is formed and the steps are done but that’s not the only thing that is done, the page is also done.
That’s the Two That’s the two means those are the two. By the two I mean that’s the right two big glaciers. By that’s the right big glaciers I mean valley glaciers and ice sheets. If you want me to stop keep on reading this page. Today you are going to learn about a valley glacier and a ice sheet. Those are both blue, cold, and big glaciers. Lets start on a valley glacier for no reason. A valley glacier is called a valley glacier because a valley glacier slides slowly down a valley. Isn’t that obvious. A valley glacier also can’t spread while others do spread for example an ice sheet glacier. Now lets go to the giant glacier which could cover a whole continent and it is really thick. Which is an ice sheet glacier. Do you know how long ice sheets existed? 10,20,30,40,50,60,70,80,90,100. You are so close it is 10,000 years Now you know the two by the two I mean those two giant glaciers coming after us, quickly turn the page.
Watch Out the Giant Ice Cube is Coming Ok, imagine a ice cube sliding down a hill It is like a glacier because glaciers like down hills. Now imagine a monster glacier. It will carve everything in its way. Now you can stop imagining things and finish reading. A glacier could shape the land in many ways. For example a valley glacier can carve the valley floors and make the floor sink into a U shape. It can also scrap the walls so it gets bigger. It will make a big lake. Sometimes they end up in rivers and pick up rocks and soil so the river gets deeper. Sometimes glaciers push rocks and make hills called moraines. All of those stuff changes the landscapes prettier. All of those stuff also might make good stuff like lakes, but it also makes really good farm land.
Constructive or destructive? Glaciers are both constructive and destructive. They break stuff and build stuff. Now let me tell you how they are both constructive and destructive. One reason they are both constructive and destructive is because when a valley glacier carves a valley it is destructive and when the glacier melts the hole that the glacier carved fills up with water it makes a lake and that is constructive. Another they are both constructive and destructive is because a glacier pulls out rocks and plants and make really smoothes long paths. That’s how the awesome glacier is both constructive and destructive.
