The Atmosphere Environment
This chapter discusses:
The significance of the Atmosphere
The composition of the Atmosphere
The layers of the atmosphere
The Atmospheric Circulation
Importance
Atmosphere – a thin layer of air that forms a protective covering around Earth.
It keeps Earth’s temperature in a range that can support life.
It also care for life-forms from some of the Sun’s harmful rays.
The Composition of Atmosphere
The Atmosphere** layer of gas that surrounds Earth more commonly known as “air”.
Atmosphere. How do you know its there
Is this “air” that surrounds us considered matter? Does it weigh anything? How do you know?
Think about it and decide on an answer.
Talk in groups with the person who sits by you
Be ready to tell the class what you decided and why.
Weight of the atmosphere
Gases are in the atmosphere.
They are things we learned about in the periodic table: Nitrogen, Oxygen, Carbon Dioxide, Hydrogen
It is matter! Sound can travel through it.
Even though you can’t see them, Atoms make up gases.
Are some atoms bigger than others?
Are their atomic weights all the same?
Helium vs. Carbon Dioxide
Do you think of helium as light and floating or heavy and falling?
Do you think about Carbon Dioxide as light and floating or heavy and falling….think about the gas released from dry ice… does it go up or down?

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. History of Earth
• Earth and the other planets in the Solar System formed 4.54
billion years ago.
• About 535 million years ago there have been five mass extinctions.
• The last extinction event occurred 65 million years ago, when a
meteorite collision probably triggered the extinction of the (non-avian)
dinosaurs and other large reptiles years ago.
• The development of photosynthesis allowed the Sun's energy to be
harvested directly by life forms; the resultant oxygen accumulated in
the atmosphere and resulted in a layer of ozone (a form of molecular
oxygen [O3]) in the upper atmosphere
3. Graphics in Solar System
Earth:
• the third planet.
• the fifth largest planet.
• the densest planet.
• has only one satellite, the Moon.
• has distance – 149600000 km from the
Sun.
4. Atmosphere of Earth
• The atmospheric pressure on the surface of the Earth averages
101.325 kPa, with a scale height of about 8.5 km.
• The Earth's atmosphere is composed mainly of nitrogen (77%),
oxygen (21%), argon (.93%), and carbon dioxide (0.03%).
• Layers:
hydrosphere
stratosphere
troposphere
biosphere
lithosphere
ionosphere
6. FACTS ABOUT EARTH
• Earth is the only planet whose English name does not derive from
Greek/Roman mythology.
• The Earth is 4.5 to 4.6 billion years old, but the oldest known rocks
are about 4 billion years old.
• There is no record of the critical period when life was first getting
started.
• The oxygen in Earth's atmosphere is produced and maintained by
biological processes.
• Earth has a modest magnetic field produced by electric currents in
the outer core
7. Moon
• It is called Luna by the Romans, Selene and Artemis by the
Greeks, and many other names in other mythologies .
• It is the second brightest object in the sky after the Sun
• As the Moon orbits around the Earth once per month, the angle
between the Earth, the Moon and the Sun changes
• Moon was first visited by the Soviet spacecraft Luna 2 in 1959
• The first landing was on July 20, 1969 and the last was in
December 1972
• The gravitational forces between the Earth and the Moon cause
tides.
• The Moon's gravitational attraction is stronger on the side of
the Earth nearest to the Moon and weaker on the opposite side
• The Moon has no atmosphere
• The Moon's crust averages 68 km thick
• Most rocks on the surface of the Moon seem to be between 4.6
and 3 billion years old.

rock, ash, and gases to escape from below the surface.
• Volcanoes are generally found where tectonic plates are pulled
apart or come together. .
• Mid-Atlantic Ridge- example of volcanoes caused by "divergent
tectonic plates“.
• the Pacific Ring of Fire- example of volcanoes caused by
"convergent tectonic plates”.
• Volcanoes also formed by-
Stretching and thinning of the Earth's crust called "non-hotspot
intraplate volcanism“.
“
Mantle plums called Hotspot volcanoes” found elsewhere in the
solar system, especially on rocky planets and moons .
15. Meteoroids
• If you have a dark clear sky you will probably see a few meteroids per
hour on an average night.
• During one of the annual meteor showers you may see as
many as 100/hour.
• Very bright meteors are known as fireballs.
• One of the Martian meteorites, known as ALH84001 (left), is
believed to show evidence of early life on Mars
• The largest found meteorite Hoba, in Namibia weighs 60 tons.
• A very large number of meteoroids enter the Earth's
atmosphere each day amounting to more than a hundred tons of
material
• The sound of the explosion of meteroid fall in Tunguska was heard
half-way around the world in London..
• One of these hits the Earth about once in a million years or so on the
average

17. Ozone layer
• The ozone layer" refers to the ozone within stratosphere,
where over 90% of the earth's ozone resides. Ozone is
an irritating, corrosive, colorless gas with a smell
something like burning electrical wiring. In fact, ozone is
easily produced by any high-voltage electrical arc (spark
plugs, Van de Graff generators, Tesla coils, arc welders).
Each molecule of ozone has three oxygen atoms and is
produced when oxygen molecules (O2) are broken up by
energetic electrons or high energy radiation.
