VERTICAL STRUCTURE OF THE ATMOSPHERE

The ATMOSPHERE basically blankets the Earth,keeping the temperature stable and protecting living organisms from harmful solar radiation.This protective combination of gases extends hundreds of kilometers from the planets surface to space. 
THE ATMOSPHERE AND ITS LAYERS

THE STRUCTURE OF THE ATMOSPHERE EDUCATIONAL VIDEO(FROM YOUTUBE):

THERMOSPHERE:


The thermosphere is the layer of the Earth's Atmosphere directly above the mesosphere and directly below the exosphere. Within this layer,(UV) ultraviolet radiation causes ionazation. The International Space station has a stable orbit within the middle of the thermosphere, between 320 and 380 kilometres (200 and 240 mi). Auroras also occur in the thermosphere.




MESOSPHERE:


The mesosphere  is the layer of the  Earth's Atmosphere  that is directly above the stratosphere and directly below the thermosphere. In the mesosphere temperature decreases with increasing height. The upper boundary of the mesosphere is the mesopause, which can be the coldest naturally occurring place on Earth with temperatures below 130 K. The exact upper and lower boundaries of the mesosphere vary with latitude and with season, but the lower boundary of the mesosphere is usually located at heights of about 50 km above the Earth's surface and the mesopause is usually at heights near 100 km, except at middle and high latitudes in summer where it descends to heights of about 85 km.




STRATOSPHERE:
The stratosphere is the second major layer of  Earth's Atmosphere, just above the troposphere, and below the mesosphere. It is stratified in temperature, with warmer layers higher up and cooler layers farther down. This is in contrast to the troposphere near the Earth's surface, which is cooler higher up and warmer farther down. The border of the troposphere and stratosphere, the tropopause, is marked by where this inversion begins, which in terms of atmospheric thermodynamics is the equilibrium level. The stratosphere is situated between about 10 km (6 mi) and 50 km (30 mi) altitude above the surface at moderate latitudes, while at the poles it starts at about 8 km (5 mi) altitude


TROPOSPHERE:


The troposphere is the lowest portion of Earth's atmosphere. It contains approximately 80% of the atmosphere's mass and 99% of its water vapor and aerosols. The average depth of the troposphere is approximately 17 km (11 mi) in the middle latitudes. It is deeper in the tropics, up to 20 km (12 mi), and shallower near the polar regions, at 7 km (4.3 mi) in summer, and indistinct in winter. The lowest part of the troposphere, where friction with the Earth's surface influences air flow, is the planetary boundary layer. This layer is typically a few hundred meters to 2 km (1.2 mi) deep depending on the landform and time of day. The border between the troposphere and stratosphere, called the tropopause, is a temperature inversion.


VERTICAL STRUCTURE OF THE ATMOSPHERE PICTURE:
Q:Why are the four major layers of the atmosphere separated where they are?
A:They are separated because the different layers have different characteristics like their temperature , width ,  even chemical composition is a difference among them.


Shows height and the area span of the layers:
Exosphere: from 500 – 1000 km (300 – 600 mi) up to 10,000 km (6,000 mi), 
Ionosphere: It is located in the thermosphere and is responsible for auroras.
Thermosphere: from 80 – 85 km (265,000 – 285,000 ft) to 640+ km (400+ mi), temperature increasing with height.
Mesosphere: The mesosphere extends from about 50 km (160,000 ft) to the range of 80 to 85 km (265,000 – 285,000 ft), 
StratosphereThe stratosphere extends from the troposphere's 7 to 17 km (23,000 – 60,000 ft) range to about 50 km (160,000 ft). 
Troposphere: The troposphere is the lowest layer of the atmosphere; it begins at the surface and extends to between 7 km (23,000 ft) at the poles and 17 km (60,000 ft) at the equator,



Q:What increases the temperature in the stratosphere?
A:Ozone layer absorbs ULTRA VIOLET (UV) rays from the sun and converts this energy into heat,causing air temperature to increase


Q:Can planes fly in the mesosphere? Why or why not?
A:No they cant because the Air in the mesosphere is thin and also because solar radiation passes through freely in the mesosphere which is dangerous


Q:On what does the temperature in the thermosphere depend?
 A:The oxygen in the thermosphere absorbs ULTRA VIOLET rays  it gains from the sun.It is so hot there because nitrogen and oxygen in the atmosphere absorb a lot of radiation from space and convert it to heat.

THE LORAX ANSWERS...."I SPEAK FOR THE TREES"



INTRODUCTION TO THE MOVIE THE LORAX




THE LORAX MOVIE TRAILER (FROM YOUTUBE):



Dr.Seuss The Lorax is a book turned into an animated film.The movie same as the book talks and teaches about the conservation of the environment. What not to do to the Environment and what are consequences could be if we are careless.


QUESTIONS OF THE MOVIE "THE LORAX"


1.What did the Once-ler do to upset the balance of the ecosystem?




2.What effect did his business have on the living things on the ecosystem?




3.What effect did his business have on the water and the air in the ecosystem.How did this affect the living things?




4.Whats the moral of the story?




ANSWERS


1. Once-ler cut the trees in the forest




2.The water was polluted and the air decreased,people were having a hard time breathing and the animals were losing their habitat.




3.Because of his business of production, The environment was affected and entirely being destroyed by his production machine. This affected everyone..


4.We must take care of our environment for us and all the other living things in the world.

FRESHMEN LIFE JUST STARTING ITS CHALLENGES

Freshmen Life just Starting....


Starting your high school years is hard but its even more harder if you start it in here in NAGA CITY SCIENCE HIGH SCHOOL...
School's Main Building (with Art by my Batch mates)
With this school's prestige and its record for being best known for its bright students,being one of them is a great honor.Walking in a public place wearing the school's uniform,patch and ID will make people petrified in awe.I have never felt anything like what I have felt when I entered the old Computer shop I used to spend 3-8 hours just playing,My old friends were shocked it was like an atomic bomb dropped outside, They were in awe to see me wear the school's uniform and its name.


Your Time in this school depends on you,It depends on you on how long you are gonna stay as a student of this school or are you going to be or let yourself be a memory of the past.It will depend on your capabilities as teenager.You must use what ever you have learned from your elementary life and put those things you have learned about into good use.


I myself know that I will have a hard time in this school but I will concentrate and prioritize my time on my work.The first few weeks of this school is going to be easy as I expected during my summer vacation but that should not fool you and me,because behind that time of relaxing comes a time hardship and challenges.It is when the will,strength,integrity,discipline,intelligence and dedication of the students will be tested and strained,All of those characteristics will be pushed to their very limits they will be remastered and rehearsed.The weak and the ones who don't have the will to fight will be separated and kicked out..


I talk like I'm not vulnerable to being removed from this school but I am vulnerable from being out of the picture.Even the smartest person in class will always have a chance of being kicked out.Our time in this school will be a test of will,strength,integrity,discipline,intelligence and dedication.
