Explanation: The atmosphere
Introduction
Earth. It is made up of the spheres we call the geosphere, biosphere, atmosphere and hydrosphere. Each sphere has it's own important role, making the earth a habitable place. In this explanation, I am going to talk about the atmosphere. The atmosphere is a blanket of gas which surrounds the earth, without the atmosphere, the biosphere wouldn’t be able to live. The atmosphere keeps the temperature on earth moderate. The atmosphere is important.
What are the layers of the Atmosphere?
The layers of the atmosphere are the Troposphere, Stratosphere, Mesosphere, Thermosphere, Ionosphere and Exosphere.
First the troposphere, the troposphere is the lowest layer of the earth’s atmosphere, it contains 99% of earth’ water vapour. The word Tropo means “ turn, toward, change” reflecting that water and air moving in a circle plays an important role in the troposphere’s behaviour, and sphere meaning the earth.
Secondly the Stratosphere, it is the second layer in the atmosphere after the troposphere. The stratosphere absorbs the UV rays because the Ozone layer is in the stratosphere. The winds in the Stratosphere can far exceed the winds in the troposphere reaching nearly 220km per hour.
Halfway through is the mesosphere, the word mesos means middle making it the middle sphere. The mesosphere is the coldest layer with temperatures up to -143°C also this is the layer which meteors start to burn up.
Coming close to the end is the Thermosphere. Applying the fact that it has Thermo in its name it is the hottest layer Temperatures ascending up to 1’700°C or more. This layer is also where UV radiation causes photoionization. Some people think that the thermosphere is apart of space because the air density is so low. Even though the ozone layer protects us from the sun, the oxygen and the nitrogen are bombarded by radiation and energetic particles from the sun, causing molecules to split into atoms creating heat.
Last but not least combining the two layers is the Ionosphere and the Exosphere. Firstly the ionosphere wouldn’t exist if it were not for the sun’s UV rays. The ionosphere is a shell of electrons and electrically charged atoms and molecules that surround the earth. The purpose of the Ionosphere is that it influences radio propagation to distant places on earth. Finally the exosphere, it’s basically outer space, no one can survive in the exosphere unless you have an air canister from the troposphere. This is the layer where satellites orbit the earth and take cool pictures!
In conclusion, the atmosphere is a bunch of layers surrounding earth so you can live and breath. Without it, the biosphere wouldn’t be able to live and I wouldn’t be writing this explanation to inform you about it.
Glossary
Water vapour: water in a gaseous state
Ascending: increasing in size
Radiation: Energy that moves from one place to another
Photoionization: when electrons come out from an atom, ion or molecule by the absorption of photons.
Photons: a particle of light
Oxygen: a colourless gas
↑
Nitrogen: Same thing
Electrons: tiny particales
Atoms: The smallest amount of substance which can take part in a chemical reaction
Propagation is any of the ways which a wave ( transport of energy) moves.

Volcano description
The titanium white lightning, which are veins in a human body, crackles like vegetables on a barbeque. It is a weaver ant colony dominantly expanding their presence throughout the forest. In the middle of nowhere black paint swiftly ushers down the burnt sienna clay mould while the “creation” violently spews out molten rocks, SpLaT sPLat! Ash in the air builds up, the aroma smells like a burnt Cuban cigar. Eventually, the vicious volcano dies down, life barely alive. The dense air diminishes and in the middle of nowhere without a sound, the eruption comes to an end…

As careless as someone guessing their maths test, the athletes ran in the muddy field with no hesitation. Their abstract trainers squelching with every footstep. Although the parents on the sideline are watching, their feet are also drenched in mud by the rain on previous days. Parents, joyfully cheering the kids, stood around the barrier like a cheetah stalking their prey. Rundown, pear shaded, the building stood in a stationary position watching over the sweaty runners. Leisurely swaying side to side, the highest tree looks into the atmosphere of tranquillity. It's brothers below it are almost symmetrical, their autumnal leaves fall off gracefully as the clouds cover the horizon and the day comes to an end.

The day a man lost his lotto ticket
Title: The day a man lost his ticket
It was high noon, the sun shone like a candle in an abandoned home. This was in a town called Seren there weren't many people nor any cars passing by. Ding-Ding, ding ding the dairy shops sensor echoed around the shop as a man named Peter walked in,
“What would you like?” The woman at the cashier asked
“ I would do myself a lottery ticket thank you,” Peter replied. Peter is unlucky, he doesn't get what he needs and he is living off benefit. Winning the lottery would be a huge milestone for him.
Scrape, scrape “ Please just one more five, YES I won the lottery I need to go to turn this in right now!” Peter was so dumbfounded he was left for words. Thump OOF! Peter was a hay bale which tumbled onto the soft, lush grass. YawN. When Peter woke up unconscious he started frantically searching his clothes for the missing lotto ticket but he had no luck. The dairy owner saw the man and she asked about the situation, Peter told her and she also started looking for the missing lotto ticket. Unfortunately, the woman also had no luck finding it until…
A mysterious man in a dull, black hoodie approached them and asked in a polite way,
“ Is this yours?” Peter’s smile was so high it nearly reached Mt Everest, he gladly accepted it from the man. The mysterious man strutted along the sidewalk like geese on the grass. Peter turned the ticket in. If those people wouldn't have helped him he would have never won the lottery.
The clouds and sun scrambled away as Peter strolled back to his motel. He hopped on his Kings single bed and daydreamed “ I wonder what would have happened if those people were not there.” Fate was on Peter’s side today and he continued to live a happy life without worries.
