Structure of atmosphere by Muhammad Fahad Ansari 12IEEM14
The document summarizes the composition and structure of the atmosphere. It discusses that the atmosphere is composed of 78% nitrogen, 21% oxygen and trace amounts of other gases. It also notes there are variable gases like water vapor and particulates suspended in the air. The structure of the atmosphere consists of four layers - the troposphere closest to the surface which contains most of the atmosphere, the stratosphere above it which contains the ozone layer, the mesosphere and thermosphere above that. Each layer has distinctive temperature characteristics.
composition &structure of atmosphere
The document describes the composition and structure of Earth's atmosphere. It is divided into multiple layers based on chemical composition, thermal properties, and electromagnetic properties. The major layers from lowest to highest are: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique characteristics such as varying temperature profiles and concentrations of different gases. The thermosphere and lower layers contain the ionosphere, where solar radiation ionizes gases to form a region that can reflect radio waves.
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.

Each layer is defined by changes in temperature at increasing altitudes from Earth's surface. The troposphere temperature decreases with altitude and contains most of the atmosphere. The stratosphere temperature increases with altitude due to ozone absorption of UV rays. The mesosphere is the coldest layer where temperature again decreases with altitude.
The EARTH's Atmosphere and major components
The atmosphere is composed of layers of gases that surround Earth and other celestial bodies. It protects the planet from harmful radiation and regulates temperature, providing suitable conditions for life. Earth's atmosphere extends over 500 km high and is made up primarily of nitrogen (78%) and oxygen (21%), with trace amounts of other gases. It has distinct layers including the troposphere where weather occurs, the stratosphere containing the ozone layer that protects from UV rays, the mesosphere which is the coldest layer, the thermosphere with high temperatures from solar absorption, and the exosphere merging with space. Overall, the atmosphere plays a crucial role in maintaining habitable conditions on Earth.

The Earth's atmosphere is divided into five layers - the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the lowest layer where weather occurs. Above that is the stratosphere, where temperature increases with altitude due to ozone absorbing UV radiation. The mesosphere is the coldest region and helps protect the Earth from meteoroids. The thermosphere is the highest layer and can reach 2000°C, where the aurora occurs. The exosphere merges into outer space with atoms and molecules escaping.

This document provides information about the layers of Earth's atmosphere. It describes the principal layers from lowest to highest as the troposphere, stratosphere, mesosphere, thermosphere (which includes the ionosphere and exosphere), and exosphere. For each layer it discusses the altitude ranges and key characteristics, such as temperature profiles and composition of gases. The document also provides background on the overall composition of air and major components like nitrogen, oxygen, and carbon dioxide.
LAYERS OF ATMOSPHERE
The document discusses the composition and structure of Earth's atmosphere. It is composed primarily of nitrogen and oxygen. The atmosphere has five layers - the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer varies in temperature and air density, with the lowest layers being densest and warmer closer to Earth's surface. The stratosphere contains the ozone layer which protects the planet.

The document summarizes key information about Earth's atmosphere, including its composition, layers, and importance. It discusses the following main points:
1. Earth's atmosphere is made up primarily of nitrogen (78%) and oxygen (21%), along with smaller amounts of other gases like carbon dioxide and argon.
2. The atmosphere is divided into four main layers - the troposphere, stratosphere, mesosphere, and thermosphere - which vary in temperature and density.
3. Greenhouse gases like carbon dioxide and methane trap heat in the lower atmosphere, creating Earth's natural greenhouse effect and warm temperatures that support life. Increased CO2 levels are enhancing the greenhouse effect and global warming.
Layers of Atmosphere.pptx
The document discusses the five layers of the atmosphere: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. It provides details on the characteristics of each layer, including temperature variations and important gases. The troposphere contains most of the air and water vapor and is where weather occurs. The stratosphere contains the ozone layer which protects from UV rays. The thermosphere is very hot and contains the aurora phenomenon.
astronomy
The document describes the layers of the Earth's atmosphere. It is divided into four main layers from lowest to highest: the troposphere, stratosphere, mesosphere, and thermosphere. Each layer has a different temperature and composition. The troposphere is closest to Earth's surface and contains 75-80% of the atmosphere. Above that is the stratosphere, which contains the ozone layer that protects the Earth. The mesosphere is the middle layer, and the outermost layer, the thermosphere, contains the ionosphere and extends into space.

The biofloc is a protein-rich aggregate of organic material and microorganisms that forms in aquaculture systems. Biofloc technology maintains water quality and provides nutrients by balancing carbon and nitrogen through the addition of carbon sources like molasses. It has been successfully used in tilapia and shrimp farming and allows for high stocking densities through natural water treatment. Key factors that must be controlled include carbon to nitrogen ratio, dissolved oxygen, pH, and ammonia, nitrite and nitrate levels.
