* The atmosphere is composed of gases, water vapour and dust particles * The proportion of gases changes in the higher layers of the atmosphere in such a way that oxygen will be almost in negligible quantity at the height of 120 km * Similarly, carbon dioxide and water vapour are found only up to 9o km from the surface of the earth.
Composition of the Atmosphere 17.1 Atmosphere Characteristics Weather is constantly changing, and it refers to the state of the atmosphere at any given time and place. Climate, however, is based on observations of weather that have been collected over many years. Climate helps describe a place or region.

Introduction This section examines the atmosphere as a system, and several atmospheric phenomena that have become critical in the understanding and guardianship of our environment. The current state of the atmosphere is the result of a multitude of
Students will learn about the composition and structure of the atmosphere by creating a flip book of the layers of the atmosphere using the jigsaw strategy. In the summative assessment, students will write an article describing how the layers of the atmosphere sustain life on our planet.
Composition of the atmosphere Except for water vapor, whose atmospheric abundance varies from practically zero up to 4%, the fractions of the major atmospheric components N 2 , O 2 , and Ar are remarkably uniform below about 100 km.
(ii) Draw a suitable diagram for the structure of the atmosphere and label it and describe it. Answer The atmosphere consists of different layers with varying density and temperature.
In this chapter we describe the chemical composition of the atmosphere and key physical properties of air. We discuss the equation of state of air (the connection between pressure, density and temperature) and key properties of moist air. In particular, we will learn that warm air usually holds much more moisture than cold air, a fact that has enormous implications for the climate of the
Above 50 miles, the chemical composition of the atmosphere changes with altitude. This layer is known as the upper atmosphere or heterosphere. This upper layer is also known as the thermosphere and it extends outward several thousand miles with no real boundary between the upper atmosphere and space. Fig. 2: Layers of the atmosphere (NASA) Though the atmosphere extends outward several …
Introduction. The earth’s atmosphere is the layer of gases and aerosols surrounding the planet and held by the earth’s gravitational force. The composition and structure of the atmosphere define its role, both as a producer of weather and a protector of life.

Structure of the atmosphere. We commonly think of gas molecules as moving about in a completely random manner, but the Earth’s gravitational field causes downward motions to be very slightly favored so that the molecules in any thin layer of the air collide more frequently with those in the layer below.
Structure and composition of the Earth The overall composition of the Earth is very similar to that of meteorites, and because of this, it is thought that the Earth originally formed from Planetesimals composed largely of metallic iron and silicates.

Atmosphere: Structure and composition, and distribution of heat (Chapter 16) The gaseous layer of Earth is its atmosphere. In studying Earth’s atmosphere, we can study the weather and climate.
ATMOSPHERIC STRUCTURE. The vertical distribution of temperature, pressure, density, and composition of the atmosphere constitutes atmospheric structure. These quantities also vary with season and location in latitude and longitude, as well as from night to day; however under the topic of atmospheric structure, the focus is on the average variations with height above sea level. Although it …
Atmosphere Our planet earth is enveloped by a deep blanket of gases extending several thousands of kilometres above its surface. This gaseous cover of the earth is known as the atmosphere. Like land (lithosphere) and water (hydrosphere), the atmosphere is an integral part of the earth. Compared to the earth’s radius, the atmosphere appears to
The structure of the atmosphere dictates the way the atmosphere behaves and controls how weather develops near the surface of the earth. I should already be familiar with: Humidity, Temperature, Pressure, Density. Figure A: The Layers of the Atmosphere (Image from the Comet Program) The atmosphere consists of 4 layers: the troposphere, stratosphere, mesosphere, and thermosphere. …
Structure of the Atmosphere Scientists divide the atmosphere into four layers that are based on temperature changes. The layer closest to the earth is called the troposphere .
atmosphere is equal to the total weight of the gas above that level. The hydrostatic equation: dP(z) / dz = – ρ (z) g [6.4] where ρ (z) is the mass density of air at height z, and g is the acceleration of gravity.

According to the homogeneity of atmospheric composition, two layers can be defined in the atmosphere. The lower layer, up to an altitude of about 80 km above sea level is the homosphere, where due to the continuous turbulent mixing the composition of the
