The atmosphere works as a place to contain the oxygen that is necessary for life, works as a blanket to shield the earth from radiation and helps to create the different types of weather that are felt on the earth the atmosphere also contains small amounts of carbon dioxide that is necessary for. The layer of the atmosphere closest to the earth is the troposphere it begins at the surface of the earth and extends out to about 4 to 12 miles (6 to 20 km) this layer is known as the lower atmosphere. In this region of the atmosphere is the ozone layer, which absorbs most of the harmful ultraviolet radiation from the sun the temperature increases slightly with altitude in the stratosphere. 2 _a_ 18 the gas that is second in abundance in the atmosphere is a oxygen b carbon dioxide c nitrogen d water vapor _c_ 19 what is the formula for ozone. Earth's atmosphere is a very thin layer of gases covering a very thin layer just above the surface of the planet this layer of gases comprises a thickness of approximately 150 km (93 miles) and is held in place by the force of gravity this layer is subsequently divided into five main layers: the.
Our atmosphere has five primary layers which make life possible the first, the troposphere, extends from sea level to about 11 miles (17 kms) up at the equator. The earth's atmosphere consists of a layer of different gases held in place by gravity the atmosphere protects earth by absorbing solar radiation, retaining heat, and regulating temperature extremes. Earth & its atmosphere the earth's mass exerts a gravitational force that holds to the earth a large amount of gases, known as the atmosphere in this section, we will look at the layers and general composition of the atmosphere and discuss its major roles in maintaining life on earth. Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere the atmosphere thins out in each higher layer until the.
The atmosphere of earth is a layer of gases surrounding the planet earth that is retained by earth's gravity vector planet earth with a spectacular sunset elements of this image furnished by nasa. The earth's layers (strata) shown to scale credit: pubsusgsgov the thinner parts are the oceanic crust, which underlies the ocean basins at a depth of 5-10 km (~3-6 miles), while the thicker. Diagram of the layers within earth's atmosphere troposphere the troposphere starts at the earth's surface and extends 8 to 145 kilometers high (5 to 9 miles.
The atmosphere is broken down into five layers, each with its own characteristics and properties of all the layers of the atmosphere, it's the troposphere that we experience. This layer has been so named because of its situation in the middle of the five layers that is divided according to the thermal conditions of the atmosphere the mesosphere stretches at altitudes between 50 and 80 km. The layers of the atmosphere listed from lowest altitude to highest altitude are the troposphere, stratosphere, mesosphere and thermosphere the troposphere extends from the earths surface up to about 14 kilometers in altitude.
The planet is generally thought of as having three distinct atmospheres over the course of its lifetime when earth was first formed, its atmosphere was likely composed of hydrogen, helium, and other gases that contained hydrogen. Earth's composition and structure: a journey to the center of the earth's atmosphere distinct layers of gas surround the solid portion of the earth. An atmosphere (from greek ἀτμός (atmos), meaning 'vapour', and σφαῖρα (sphaira), meaning '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.
The stratosphere is one of five layers of the earth's atmosphere the other four layers include the troposphere, mesosphere, thermosphere, and exosphere the stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere just like the. Several layers can be distinguished in the atmosphere, based on characteristics such as temperature and composition the study of earth's atmosphere and its processes is called atmospheric science (aerology) early pioneers in the field include léon teisserenc de bort and richard assmann. The ozone layer or ozone shield is a region of earth's stratosphere that absorbs most of the sun's ultraviolet radiation it contains high concentrations of ozone (o 3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.
