The composition of our atmosphere near the ground is 78% nitrogen and 21% oxygen, the remaining 1% consisting of other gases, most of it argon. The composition stays the same to an altitude of at least 70 mi ( km) (except that higher up two impurities, carbon dioxide and water vapor, are missing), but the pressure drops very fast. Atmosphere layers. Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere.
The atmosphere is divided into four layers based on temperature: the troposphere, stratosphere, mesosphere, and thermosphere. The Troposphere. This is the lowest layer of the atmosphere, closest to the surface of the earth. The troposphere varies in height in different parts of the world, from about 8km above sea level at the poles, to 16km at. The envelope of gas surrounding our planet Earth, known as the atmosphere, is organized into five distinct layers. These layers start at ground level, measured at sea level, and rise into what we call outer the ground up they are:Author: Rachelle Oblack.
the presence of a magnetic field; the distance of the star from the planet (not too close, not too far) what the atmosphere itself is made of (we need oxygen!) The Importance of Gravity. An atmosphere is rather pointless if the planet’s gravitational pull isn’t strong enough to make that atmosphere stay put. Atmosphere, composition and structure. Composition of the atmosphere. Atmospheric structure. The past and future of the atmosphere. Resources. Earth ’ s atmosphere is composed of about 78% nitrogen, 21% oxygen, and % argon. The remainder, less than %, contains such trace gases as water vapor, carbon dioxide, and of these trace gases have important effects on Earth ’ s climate.

Atmosphere Review •Vital functions of the atmosphere include the following: keeps Earth's temperature steady and habitable protects from ultraviolet radiation protects from meteorite impacts provides oxygen for respiration and carbon dioxide for photosynthesis •The atmosphere consists primarily of nitrogen (78%) and oxygen (21%) gases.

SCIENCE 8, Atmosphere, CHAPTER 15 caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane.
global warming. an increase in the average temperature of the earth's atmosphere, especially a sustained increase sufficient to cause climatic change. 2 Introduction • The atmosphere is thin relative to the size of Earth. • Two common gases make up 99% of dry air. • Trace amounts of other gases play a critical role in the atmosphere.
Ironically, it is the view of Earth from the airless vacuum of space that provides us with a view of just how thin is the veil ofFile Size: KB. Life and the Evolution of Earth’s Atmosphere Stephen J.

Thinking about it, there’s a subtle kind of poetry involved with its scientific Size: 2MB. The atmosphere is layered, corresponding with how the atmosphere’s temperature changes with understanding the way temperature changes with altitude, we can learn a lot about how the atmosphere works. While weather takes place in the lower atmosphere, interesting things, such as the beautiful aurora, happen higher in the atmosphere.
The amount of oxygen in the atmosphere is about 21% and all living beings use oxygen present in the atmosphere for breathing. For the burning of fuels like wood, coal, gas etc. oxygen is essential and carbon dioxide gas is produced by their burning. The main sources of oxygen in the atmosphere are plants and trees.

The early Greeks considered "air" to be one of four elementary substances; along with earth, fire, and water, air was viewed as a fundamental component of the the early s, however, scientists such as John Dalton recognized that the atmosphere was in fact composed of several chemically distinct gases, which he was able to separate and.
The presence oxygen began to appear apparently from being released by photosynthesizing algae. The third atmosphere came into play when the planet began to stretch its legs, so to speak.

Atmosphere - Atmosphere - The atmospheres of other planets: Astronomical bodies retain an atmosphere when their escape velocity is significantly larger than the average molecular velocity of the gases present in the atmosphere.
There are 8 planets and over moons in the solar system. Of these, the planets Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune have significant atmospheres. The rocky, inner planets of our solar system vary in sizes, atmospheres, and temperatures. Mercury, the smallest and closest to the sun has no atmosphere and extremes of temperature that average to about that predicted by our simple black bodythe next largest and farthest from the sun, has a very tenuous atmosphere that is mostly CO 2 and an average temperature close to or just a.
ClearIAS Team has been receiving a lot of support and encouragement from our loving readers for our easy-to-understand articles on Geography. (See Major Ocean Currents: How to learn faster?) Having covered most of the important concepts in Lithosphere and Hydrosphere, in this article, we are going to discuss the composition and structure of the Earth’s Atmosphere in detail.
Gases in Atmosphere. The atmospheric composition of gas on Earth is largely conducted by the by-products of the life that it nurse. Dry air from earth’s atmosphere contains % of carbon dioxide, % of oxygen, % of nitrogen and % of argon.
Atmosphere: Atmospheric Gases; The atmosphere is an envelope of air that surrounds the Earth and rests upon its surface. It is as much a part of the Earth as the seas or the land, but air differs from land and water as it is a mixture of gases.
The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth's atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature.
The atmosphere is also a major temporary repository of a number of chemical elements that move in a cyclic manner between the hydrosphere, atmosphere, and the upper lithosphere. Finally, the atmosphere is a site for a large variety of complex photochemically initiated reactions involving both natural and anthropogenic substances.
An atmosphere (from Ancient Greek ἀτμός (atmos), meaning 'vapour', and σφαῖρα (sphaira), meaning 'ball' or 'sphere') is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.
An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low. Figure Structure of Earth’s Atmosphere.
Height increases up the left side of the diagram, and the names of the different atmospheric layers are shown at the right. In the upper ionosphere, ultraviolet radiation from the Sun can strip electrons from their atoms, leaving the atmosphere ionized.
Thickness of the Atmosphere Most of the atmospheric mass is confined in the lowest km above the sea level. The thickness of the atmosphere is only about 2% of Earth’s thickness (Earth’s radius = ~km). Because of the shallowness of the atmosphere, its motions over.
How to Get an Atmosphere. Saturn's moon Titan belongs to a very select club within the solar system. It is one of only four "terrestrial" planets or moons—those with solid bodies, as opposed to.The Earth’s atmosphere has five distinct layers generally measured by temperature gradients, from the troposphere near the Earth's surface at an average 15 degrees Celsius to the temperature of the exosphere layer at 1, degrees Celsius.
These layers create a habitable environment to sustain life.
