The atmosphere is divided into five main layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is where weather occurs and contains around 80% of the atmosphere's mass. The stratosphere is above the troposphere and contains the ozone layer. Temperature decreases with increasing altitude in the troposphere but increases in the upper stratosphere due to ozone.

Factors affecting climate
The document discusses six key factors that affect climate: latitude, altitude, distance from the sea, relief, pressure and wind systems, and ocean currents. Latitude affects temperature, with tropical regions being hot, polar regions being cold, and temperate regions having moderate temperatures. Altitude also influences temperature, with temperatures decreasing as elevation increases. Proximity to the sea moderates climate, while inland areas experience more extreme temperatures. Relief such as mountains can act as barriers or influence rainfall distribution. Pressure and wind systems determine rainfall amounts and patterns. Ocean currents also impact local climate, with warm currents raising and cold currents lowering temperatures.

Earth's formation ppt
This document summarizes the formation of the solar system according to the core accretion model. It explains that the solar system began as a solar nebula that collapsed under gravity to form the sun. Heavier elements near the sun merged to form terrestrial planets, while lighter elements further from the sun formed gas giants. The earliest Earth had a hot molten surface and atmosphere of gases like hydrogen and carbon dioxide. Over time, the Earth cooled and developed layers, water was introduced via asteroids, and a water cycle, plate tectonics, and life emerged.
Atmosphere Powerpoint
The document discusses the four main systems that make up Earth: the atmosphere, hydrosphere, biosphere, and geosphere. It focuses on describing the layers of the atmosphere, including the exosphere, thermosphere, mesosphere, stratosphere, and troposphere. The troposphere contains most of the weather and clouds and temperatures decrease with increased altitude. The stratosphere contains ozone that absorbs UV radiation. The mesosphere is the coldest part while the thermosphere reaches temperatures over 1,700°C and protects the Earth from radiation.
Climate
The document discusses key concepts relating to climate and climate change. It defines climate as the overall weather pattern of a region over a long period of time, typically 30 years. It is influenced by several factors, including latitude, altitude, distance from large bodies of water, ocean currents, and topography. Climate change refers to long-term shifts in global weather patterns and is exacerbated by human activities that release greenhouse gases and increase carbon dioxide levels in the atmosphere. Climate change can have drastic effects including rising sea levels, more severe weather events, and threatened extinction of plant and animal species.
Layers-of-atmosphere
Earth's atmosphere is divided into four main layers - the troposphere, stratosphere, mesosphere, and thermosphere - based on changes in temperature.
The troposphere is the lowest layer where weather occurs and where humans live. It contains almost all of the atmosphere's mass. The stratosphere above it contains the ozone layer and has increasing temperatures with altitude. Above that, in the mesosphere, temperatures decrease with altitude and meteoroids burn up. The outermost thermosphere has increasing temperatures with altitude and contains the ionosphere and exosphere.
Composition and structure of earth's atmosphere
The document summarizes the composition and structure of Earth's atmosphere in the following key points:
1. The atmosphere is composed primarily of nitrogen (78%) and oxygen (21%), as well as smaller amounts of gases like carbon dioxide, argon, and water vapor.
2. It is divided into five main layers based on changes in temperature: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
3. Gases like carbon dioxide and water vapor play important roles in the greenhouse effect and moderating Earth's temperature to sustain life.
Layers of the Earth
The document describes the four main layers that make up the Earth - the crust, mantle, outer core, and inner core. The crust is the outermost layer, upon which we live, and is broken into tectonic plates. Below the crust is the mantle, which is divided into the upper and lower mantle. The lower mantle is very thick and contains molten rock that moves in convection currents. Deepest inside the Earth is the core, with a liquid outer core that generates the Earth's magnetic field and a solid inner core under intense heat and pressure.

D. VELOCITY AND DENSITY VARIATION WITHIN THE EARTH
The immense amount of heat energy released from gravitational energy and from the decay of radioactive elements melted the entire planet, and it is still cooling off today. Denser materials like iron (Fe) sank into the core of the Earth, while lighter silicates (Si), other oxygen (O) compounds, and water rose near the surface.
The earth is divided into four main layers: the inner core, outer core, mantle, and crust. The core is composed mostly of iron (Fe) and is so hot that the outer core is molten, with about 10% sulphur (S). The inner core is under such extreme pressure that it remains solid. Most of the Earth's mass is in the mantle, which is composed of iron (Fe), magnesium (Mg), aluminum (Al), silicon (Si), and oxygen (O) silicate compounds. At over 1000 degrees C, the mantle is solid but can deform slowly in a plastic manner. The crust is much thinner than any of the other layers, and is composed of the least dense potassium (K), calcium (Ca) and sodium (Na) aluminum-silicate minerals. Being relatively cold, the crust is rocky and brittle, so it can fracture in earthquakes.

Mountain Ranges
Its about the characteristics of major mountain mountain range and famouse mountain ranges in the world.
Comets, asteroids & meteors
Comets and asteroids are remnants from the formation of the solar system. Comets originate from the Kuiper Belt and Oort Cloud and are icy bodies, while asteroids originate from the Main Asteroid Belt and are rocky fragments. Both have irregular shapes and sizes ranging from 1-100 km. Comets have highly elliptical orbits with periods of 75 years to millions of years, while asteroids have more rounded orbits with periods of 1-100 years. When a meteoroid from space enters the atmosphere, it becomes a meteor or "shooting star"; any fragments that reach the ground are called meteorites.
The layers of the Atmosphere
The document summarizes the different layers of Earth's atmosphere from lowest to highest:
1) Troposphere, closest to Earth's surface and containing 75% of atmosphere's mass. Temperature decreases with height.
2) Stratosphere above troposphere, contains ozone layer absorbing UV rays. Ozone layer is being depleted.
3) Mesosphere above stratosphere, temperature drops sharply with height.
4) Thermosphere above mesosphere, temperature increases with height and can reach thousands of degrees. Includes ionosphere.
5) Exosphere, the uppermost layer, where molecules can escape into space. Density is very low with few collisions.
It also discusses issues like o
Layers of the atmosphere
The troposphere is the lowest layer of the atmosphere where weather occurs and temperatures decrease with increasing altitude. Above the troposphere, the stratosphere gets hotter with altitude due to absorption of UV light by the ozone layer before cooling again at the top. The mesosphere is the coldest part of the atmosphere where most meteorites burn up before giving way to the thermosphere, the hottest layer where the ISS orbits due to absorption of solar radiation.
Forms of Energy
1. The document discusses the six main types of energy: thermal, heat, solar, chemical, electrical, and mechanical.
2. It provides examples and explanations of each type of energy, including how thermal energy is the motion of particles, heat transfers thermal energy, solar energy comes from the sun, chemical energy is stored in particles, electrical energy flows in circuits, and mechanical energy can be kinetic or potential.
3. Interactive elements like questions and diagrams are included to help explain and reinforce the concepts.
AIR MASSES AND FRONT
The document discusses air masses and fronts. It defines air masses as large bodies of air with uniform properties that form over land or water surfaces. There are four main types of air masses classified by their region of formation: maritime/continental and polar/tropical. Fronts are boundaries between unlike air masses. There are three main types of fronts: cold fronts, where cold air overtakes warm air; warm fronts, where warm air overtakes cold air; and occluded fronts, where a warm air mass is overtaken by two cooler air masses.
Characteristics of stars
This document provides information about stars, including their characteristics, sizes, colors, brightness, and life cycles. It describes how stars can be viewed through telescopes and the largest telescopes in the Philippines. Stars are classified based on their spectral type, which determines their color and temperature. They range greatly in size from red supergiants over 1,000 times the sun's radius to tiny white dwarfs only 1% of the sun's radius. The document also explains how astronomers measure and compare the apparent and absolute magnitudes of stars to determine their brightness.
atmosphere and its layers
The document describes the structure and composition of Earth's atmosphere. It is divided into five main layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere - based on how temperature and pressure change with altitude. The troposphere is the lowest layer where weather occurs. Above it is the stratosphere containing the ozone layer. Next is the mesosphere where temperature decreases, followed by the thermosphere where temperature increases with altitude. The outermost layer is the exosphere, which transitions to outer space. The atmosphere protects life, transports energy and water, and stores gases important for plants and animals.
Weather and Climate
This document provides information about weather, climate, and climates of the Philippines for a 120 minute lesson in high school earth science. It defines weather and climate, describes factors that influence climate such as latitude, altitude, proximity to bodies of water, and prevailing winds. It also outlines the four climate types in the Philippines and discusses the northeast and southwest monsoon wind systems that influence the country's seasonal rainfall patterns.
What causes seasons on earth
The document summarizes what causes seasons on Earth. It explains that seasons result from the tilt of Earth's axis relative to its orbit around the sun. This causes variations in the intensity of sunlight and day length throughout the year. Specifically, summer occurs in the Northern Hemisphere when it is tilted toward the sun, and winter occurs when it is tilted away. Spring and fall seasons experience nearly equal amounts of daylight and nighttime.
Heating The Earth
Solar radiation provides most of the energy that drives environmental processes on Earth. It warms the atmosphere and surface through various absorption, scattering, and reflection interactions as it passes through the atmosphere. Variations in solar insolation at different latitudes and across seasons are caused by changes in the orientation of the Earth relative to the sun throughout the year.
The Atmosphere
The atmosphere is composed of four main layers: the troposphere, stratosphere, mesosphere, and thermosphere. The troposphere contains around 75% of the atmosphere's mass and is where weather occurs. The stratosphere contains the ozone layer which protects the Earth from UV radiation. The thermosphere is the hottest layer due to absorption of solar radiation.

Earth Structure
The document discusses the structure and layers of the Earth. It is composed of four main layers from outermost to innermost:
1) The crust, which is the thin solid outer layer people live on made of rocks and minerals. It is divided into thicker continental crust and thinner oceanic crust.
2) The hot, dense mantle that behaves like a solid but can flow very slowly over geologic timescales. Its convection currents influence plate tectonics at the surface.
3) The liquid outer core that is composed of melted nickel and iron due to extreme heat and pressure.
4) The inner solid core formed from compressed metals vibrating in place like a solid.
Ozone
The ozone layer is found in the stratosphere and protects the Earth from harmful UV rays. Certain chemicals like CFCs released from aerosol sprays and refrigerants were depleting the ozone. This caused a large seasonal "hole" over Antarctica. The Montreal Protocol banned CFCs which has helped the ozone layer start recovering, though full recovery may take until 2050. While the ozone layer decreases UV exposure, its depletion may also impact climate change.
Prepositions
This document repeats various prepositions and phrases without any clear context or meaning. It includes the words "up", "down", "in front of", "behind", "over", "under", "on", "off", "into", "out of", "toward", "at", "away from", "outside", "inside", and "finis" repeated multiple times each without any other content. It also contains the repeated phrases "caution: cliff ahead! nevermore!" and "no animals were harmed during the creation of this film."

Atmosphere ghe
The document summarizes the layers of Earth's atmosphere. It is divided into five main layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is where weather occurs and contains gases like water vapor and carbon dioxide. The stratosphere contains the ozone layer. Temperature decreases with altitude in the troposphere but increases in the thermosphere. Air pressure is greatest in the troposphere and decreases with altitude. Solar energy drives heating and circulation in the atmosphere through the greenhouse effect.

Chapter 4 global atmosphere change
The document summarizes key aspects of the global atmosphere and climate change. It describes the composition of the atmosphere and identifies the main greenhouse gases, including carbon dioxide, methane, and nitrous oxide. It explains how human activities like burning fossil fuels have increased the concentrations of these gases, enhancing the greenhouse effect and causing global warming. The document also outlines the different layers of the atmosphere - troposphere, stratosphere, mesosphere, and thermosphere - and discusses factors like temperature and ozone concentration that characterize each layer.
Composition and Structure of Atmosphere
The document summarizes the composition and structure of the atmosphere. It is composed of several layers:
1) The troposphere, closest to Earth's surface and containing 75% of the atmosphere's mass. Temperature decreases with altitude.
2) The stratosphere above the troposphere, containing the ozone layer which absorbs UV radiation. Temperature increases with altitude here.
3) The mesosphere where temperature decreases with altitude again.
4) The thermosphere, growing very hot due to solar activity.
5) The exosphere, the uppermost layer where molecules can escape into space.
The Earth's Atmosphere Atmospheric Layers.ppt
The document describes the four main layers of Earth's atmosphere - the troposphere, stratosphere, mesosphere, and thermosphere. It provides details on the temperature and characteristics of each layer, including that the troposphere is where weather occurs and temperatures decrease with height, the stratosphere temperatures increase due to ozone, the mesosphere temperatures decrease with protective properties, and the thermosphere has increasing temperatures and is where the northern lights and space shuttles orbit occur.
Atmosphere.pptx
The atmosphere can be divided into four main layers - the troposphere, stratosphere, mesosphere, and thermosphere - based on changes in temperature. The troposphere is the lowest layer that contains the air we breathe and where weather occurs. Above that is the stratosphere, which contains a protective layer of ozone. Next is the mesosphere, the coldest layer where temperatures drop down to -100°C. The outermost layer is the thermosphere, where temperatures continually rise with altitude. The atmosphere plays a crucial role in supporting life on Earth by regulating temperature, enabling the water cycle, and protecting the planet's surface.
The earth's atmosphere atmospheric layers
The document describes the four main layers of Earth's atmosphere - the troposphere, stratosphere, mesosphere, and thermosphere. It provides details on the temperature and characteristics of each layer, including how temperature varies with altitude and key phenomena that occur within each atmospheric region. The troposphere extends to around 9 miles high and contains most of the atmosphere. Above this is the stratosphere, where temperature increases with altitude due to ozone absorption of solar radiation. Higher up are the mesosphere, where temperature decreases, and the thermosphere, where temperature again increases with the beautiful colors of the northern lights occurring in this layer.

Slide share presentation
The document discusses the composition and layers of the atmosphere. It describes the five main layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere - and some of their key characteristics. The troposphere contains weather and is closest to Earth's surface, while the stratosphere contains the ozone layer. The mesosphere is the coldest layer, and the thermosphere is the hottest despite being thin. The main gases in the atmosphere are nitrogen, oxygen, and trace amounts of other gases like carbon dioxide and water vapor. Solar energy is the driving force behind atmospheric circulation and heating of the Earth.
Atmosphere
The document discusses the composition and layers of Earth's atmosphere. It begins by explaining that the atmosphere protects Earth and drives weather patterns. It is composed primarily of nitrogen, oxygen, and traces of other gases. Early atmospheres lacked oxygen but organisms began producing it over billions of years, forming an ozone layer. The atmosphere has five main layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere - defined by temperature trends. Solar radiation and the greenhouse effect warm the atmosphere, while convection currents driven by temperature differences and the Coriolis effect produce global wind patterns like the trade winds and jet streams that influence weather. Clouds form through condensation in rising air.
What makes up weather ( whole presentation )
The document summarizes the layers of the atmosphere and factors that influence weather. It discusses the five main layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere - and characteristics of each. Weather variables like temperature, wind, moisture, and precipitation are identified. The angle and intensity of solar insolation is explained, noting it is greatest at the equator and lowest at the poles. Air pressure variations result from uneven heating and cooling, with low pressure where air is warm and high pressure where air is cool. Differences in pressure cause surface winds and convection cells in the atmosphere.
