Class response-Layers ot the atmosphere

In school for a couple of weeks we have been about the weather. A couple of days ago we learned about the layers of the atmosphere. There are four main and important layers of the atmosphere. The names of those layers are:troposphere, the stratosphere, the mesosphere and the thermosphere. The troposphere is the most lowest layer of the atmosphere and the most closest to the earth. This is where most of the weather occurs and most of the clouds are here. The troposphere is 12-15 km above the ground. The second layer that is the closest to the ground is the stratosphere. The lower part of the stratosphere is VERY cold but the temperature gets warmer and warmer as you reach the top because that's where the ozone layer is. The stratosphere extends from the top of the troposphere to 50 km above ground. The third layer that is closest to the ground is the mesosphere. The mesosphere is the coldest layer of the atmosphere with temperatures near -90 degrees Celsius and protects the earth from meteors. The mesosphere rises from about 50 km to 80 km above ground. The outer most layer of the atmosphere is the thermosphere. The thermosphere has no definite end. It just keeps going and going and going. It is broken up into two layers called the ionosphere and the exosphere. In the ionosphere gas molecules are electrically charged and all the satellites are in the exosphere. Here is a diagram that show all the layer of the atmosphere: (if you click on it, it will enlarge!)

Desert Places
by: Robert Frost

Snow falling and night falling fast, oh, fast
In a field I looked into going past,
And the ground almost covered smooth in snow,
But a few weeds and stubble showing last.

The woods around it have it--it is theirs.
All animals are smothered in their lairs.
I am too absent-spirited to count;
The loneliness includes me unawares.

And lonely as it is that loneliness
Will be more lonely ere it will be less--
A blanker whiteness of benighted snow
With no expression, nothing to express.

They cannot scare me with their empty spaces
Between stars--on stars where no human race is.
I have it in me so much nearer home
To scare myself with my own desert places.

This wonderful poem called “Desert Places” by Robert Frost uses weather by describing snow in the first verse. He talks about how snow falls so fast at night and covers everything in sight. Robert Frost’s knowledge of snow really enhances the poem because it describes how it covers everything and if he didn’t know anything about snow the poem wouldn’t have been that excellent. This poem wouldn’t have been as amazing as it is now if Robert Frost didn’t talk about snow because this entire poem talks about how the snow covers everything. If Robert Frost didn’t talk about snow in his poem the no one would be able to understand what he is trying to say. In this poem some literary devices used are personification and imagery. Personification is used when Robert Frost says “night falling fast” because night is a non-living thing and it is given a human characteristic. Imagery is used in this poem when Robert Frost mentions “the ground almost covered smooth in snow” because you can imagine that in your mind. This poem however does not expand my knowledge of snow because it describes snow and I already know a lot about it.

Class response-- Arctic Tale

Today in class we watched a documentary movie made by National Geographic called Arctic tale. The movie was about polar bears and walruses who live it the wild and how there life is changing because of global warming. The movie was pretty good except some of the parts were really shocking and kind of disgusting. Something i thought that was shocking was that the camera people didn't feed the polar bear when he was dying!! i know that they weren't allowed to but i think they should have feed the polar bear because then he wouldn't have died. My favorite part of the movie was in the beginning when the two baby polar bears were playing with each other. They looked so cute!! You can now more about the movie at this website: http://en.wikipedia.org/wiki/Arctic_Tale
