Earth's magnetic field helps to prevent this, as, normally, the solar wind would greatly enhance the escape of hydrogen. class 6. Hydrosphere Overview, Facts & Examples | What is the Hydrosphere? The atmospheres of the planets Venus and Mars are principally composed of carbon dioxide and nitrogen, argon and oxygen. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. An atmosphere (from Ancient Greek (atms)'vapour, steam', and (sphara)'sphere')[1] is a layer of gas or layers of gases that envelop a planet, and is held in place by the gravity of the planetary body. Five layers occupy those ten thousand kilometers. Kyoto Protocol Overview, Pros & Cons | What is the Kyoto Protocol? New Learning Composite Mathematics SK Gupta Anubhuti Gangal Solution. | Class 6 - 8 | Vedantu | Pritesh Sir - Did you know that the Earth's atmosphere is divided into various layers? Heating of this surface is accomplished by three physical processesradiation, conduction, and convectionand the temperature at the interface of the atmosphere and surface is a result of this heating. In the poles, it only reaches about eight kilometers up. Frost and precipitations, which depend on the atmospheric composition, also influence the relief. The next layer, themesosphere, is the coldest because the there are almost no air molecules there to absorb heat energy. Atmosphere - Major Domains of the Earth | Class 6 Geography [8] The net effect, taking the most important escape processes into account, is that an intrinsic magnetic field does not protect a planet from atmospheric escape and that for some magnetizations the presence of a magnetic field works to increase the escape rate.[9]. The mesosphere ranges from 50km to 85km, and is the layer wherein most meteors are incinerated before reaching the surface. Some planets have active atmospheres with clouds, wind, rain and powerful storms. How Do Aqueous Solutions of Ionic & Molecular Compounds Differ? During the early evolution of the atmosphere on Earth, water must have been able to exist as a liquid, since the oceans have been present for at least three billion years. We live in the troposphere, the layer closest to Earth's surface, where most clouds are found and almost all weather occurs. ins.dataset.adClient = pid; As you rise in elevation, there is less atmosphere above you weighing down on you, or in this case, your ears. When in the part of its orbit closest to the Sun, Pluto has an atmosphere of nitrogen and methane similar to Triton's, but these gases are frozen when it is farther from the Sun. Once organisms developed the capability for photosynthesis, oxygen was produced in large quantities. The Atmosphere. Author of. The smaller, rocky planets - Earth, Venus and Mars - each have thinner atmospheres, hovering above their solid surfaces. During the day, it prevents a sudden increase in the temperature of the earth and prevents the heat to escape to outer space during the night. Atmospheres have dramatic effects on the surfaces of rocky bodies. The Question and answers have been prepared according to the Class 6 exam syllabus. Earths atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. Percentage of Air in this layer is near about zero. Along with water vapor, the atmosphere allows life to survive.

Create your account. The gas giant planets in our solar system - Jupiter, Saturn, Uranus and Neptune - each have a thick, deep atmosphere. ins.id = slotId + '-asloaded'; It is the atmospheric layer that absorbs most of the ultraviolet radiation that Earth receives from the Sun. The five layers of the atmosphere are troposphere, stratosphere, mesosphere, thermosphere, and exosphere. ''Sphere'' originated from the Greek sphaira, which means ball. They write new content and verify and edit content received from contributors. In contrast, carbon dioxide is about 10 percent of the effluent. succeed. The starting of the atmosphere is different throughout Earth, as it ranges from six to 20 kilometers from the planet's surface. This chemical negatively affects the ozone layer. Thermosphere is one of the hottest layers of atmosphere. Atmosphere layer is ended here. Dry air (mixture of gases) from Earth's atmosphere contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and traces of hydrogen, helium, and other "noble" gases (by volume), but generally a variable amount of water vapor is also present, on average about 1% at sea level.[5]. Other planets, such as Venus, Earth, Mars, and the giant outer planets of the solar system, have retained an atmosphere. This is considered the lowest layer of the atmosphere, as it starts from the ground and reaches 14 kilometers up. Save my name, email, and website in this browser for the next time I comment.
