The document describes the composition and layers of the atmosphere. It states that the main components of the atmosphere are nitrogen (78.08%), oxygen (20.95%), and argon (0.93%). It also lists other minor components like carbon dioxide, water droplets, and various aerosols. The layers of the atmosphere are defined by temperature profiles and include the troposphere where weather occurs, the stratosphere containing the ozone layer, the mesosphere which is the coldest, and the thermosphere where ions are present.
This presentation talks about our atmosphere, its composition, the layers of the atmosphere, effects of EM radiation, EM spectrum, Visible spectrum, factors affecting our atmosphere, terrestrial long wave flux and how earth's radiation release and income gets balanced in brief, the sources from which the information has been taken is mentioned in the end of the presentation.
this ppt is mainly for the students of grade 7 igcse
go ahead,have a look!
follow for more ppts!
just comment whichever ppt you want next and it will be ready for u!

The earth is the only known planet, on which life exists. The present condition and properties of earth’s atmosphere are one of the main reasons for earth to support life. The atmosphere is the blanket of gases or vapours that surrounds the earth, and held together by the force of gravity.

This was my presentation for my grand demonstration teaching. If you want to see my lesson plan for this topic just click the link. http://www.slideshare.net/ubuntu0125/detailed-lesson-plan-earths-atmosphere
This presentation is intended for people who are studying English as a second language. I has flashcards that can be used to review prepositions of time.
its a small view of layers of atmosphere! maximum every person have to know this type of information etiher they're engineer, doctor or accountant! it's a basic for our lives!

This PowerPoint is one small part of the Weather and Climate unit from www.sciencepowerpoint.com. This unit consists of a five part 2500+ slide PowerPoint roadmap, 14 page bundled homework package, modified homework, detailed answer keys, 19 pages of unit notes for students who may require assistance, follow along worksheets, and many review games. The homework and lesson notes chronologically follow the PowerPoint slideshow. The answer keys and unit notes are great for support professionals. The activities and discussion questions in the slideshow are meaningful. The PowerPoint includes built-in instructions, visuals, and review questions. Also included are critical class notes (color coded red), project ideas, video links, and review games. This unit also includes four PowerPoint review games (110+ slides each with Answers), 38+ video links, lab handouts, activity sheets, rubrics, materials list, templates, guides, and much more. Also included is a 190 slide first day of school PowerPoint presentation.

I teach a weekly online class to virtual students in my school, focusing on 5th grade Writing Strategies. This PowerPoint is one of the lessons that I designed for the class. It is aligned to CA standards for fifth grade, and also aligned to the K12 curriculum so that students can get guided instruction on one of their lessons and be able to mark it off at the end.
3. Other Components of the
Atmosphere
• Water Droplets
• Ice Crystals
• Sulfuric Acid Aerosols
• Volcanic Ash
• Windblown Dust
• Sea Salt
• Human Pollutants
3. Composition of the Atmosphere
4. Aerosols
Aerosols
Any solid or liquid particle in the
atmosphere.
•Natural (e.g. dust) and human (e.g.
soot) sources.
•Can remain suspended for long
periods of time (days to weeks).
•Contribute to cloud formation and
precipitation by acting as
condensation nuclei.
5. Aerosols: Saharan Dust Storm
Dust particles are about 10 micro-meters in
size (0.00001 meters). Roughly 1/10 the
width of a human hair. Big ones settle out..
10. Structure (Layers) of the
Atmosphere
• Defined by Temperature Profiles
• Troposphere
– Where Weather Happens
• Stratosphere
– Ozone Layer
• Mesosphere
• Thermosphere
– Ionosphere
4. Layers in the atmosphere are defined by temperature profiles
13. Troposphere
• Heating of the Surface creates warm air at
surface
• Warm air rises, but air expands as it rises
and cools as it expands (Adiabatic
cooling)
• Heating + Adiabatic Cooling = Warm air at
surface, cooler air above
• Buoyancy = Cool air at surface, warmer
air above
• Two opposing tendencies = constant
turnover the atmosphere are defined by temperature profiles
4. Layers in
14. The Stratosphere
• Dry
• Absorbs ultraviolet
radiation (UV)
• Ozone layer is here
• Ozone (O3) absorbs
much UV C and
UV B waves.
15. Stratosphere
• Altitude 11-50 km
• Temperature increases with altitude
• -60 C at base to 0 C at top
• Reason: absorption of solar energy to
make ozone at upper levels (ozone layer)
• Ozone (O3) is effective at absorbing solar
ultraviolet radiation
4. Layers in the atmosphere are defined by temperature profiles
17. Mesosphere
• 50 – 80 km altitude
• Temperature decreases with altitude
• 0 C at base, -95 C at top
• Top is coldest region of atmosphere
4. Layers in the atmosphere are defined by temperature profiles
18. The Thermosphere (Ionosphere)
• Region of charged ions (positive) and
electrons
• Electrons are torn off atoms by sunlight of
short wavelengths
• Electrons don’t recombine easily because
the distance between molecules is large
at high altitudes and collisions are not
frequent
19. Thermosphere
• 80 km and above
• Temperature increases with altitude as
atoms accelerated by solar radiation
• -95 C at base to 100 C at 120 km
• Heat content negligible
• Traces of atmosphere to 1000 km
• Formerly called Ionosphere
