Large amounts of oxygen can be extracted from liquefied air through a process known as fractional distillation. air pollution create by a mixture of smoke and fog. iron. Oxygen accounts for nearly half of the mass of the earth's crust, two thirds of the mass of the human body and nine tenths of the mass of water. These two elements are by far the most abundant in the Universe. Most of the rest is helium. toxic fumes emitted from automobiles. Like most planets Earth's earliest atmosphere was dominated by hydrogen and helium. This chemical compound found in the Earth's atmosphere is not a large percentage of the Earth's atmosphere; it does, however, play an important role in maintaining life on Earth because it helps to trap heat and keep the planet warm. Argon. Oxygen is an element which is highly reactive and also easily combines with other elements. Element No. Earth is the third planet from the Sun and the only astronomical object known to harbor life.About 29% of Earth's surface is land consisting of continents and islands.The remaining 71% is covered with water, mostly by oceans but also by lakes, rivers, and other fresh water, which together constitute the hydrosphere.Much of Earth's polar regions are covered in ice. Oxygen makes up 46.1% of the mass of Earth’s crust (the relatively thin layer of rock forming Earth’s surface), mostly in combination with other elements, while silicon makes up 28.5%. The most abundant gas in the atmosphere is nitrogen, with oxygen second. 94 percent of the human body is made up of the key elements oxygen, carbon, and hydrogen. silicon. They make up almost 99% of the atmosphere by mass. ... oxygen A gas that makes up about 21 percent of Earth's atmosphere. Makes up less than 1% of the Earth's atmosphere; it … 2. it is unreactive with materials that make up the solid earth 3. it is very stable in the presence of solar radiation. Spectrum A was observed when that element was heated in a laboratory. Nitrogen and oxygen. Sometimes fires burn down large areas of forests that are part of the biosphere. 6 Answers. Helium makes up most of the remaining 25%. Spectrum B shows the same element as seen in the light from a distant star. the contamination of the atmosphere by the introduction of pollutants from human and natural sources. … It is arguably the most important element to life on Earth, and indeed it comprises roughly two thirds of the human body’s components. Air Pollution. The atmosphere of Earth is the layer of gases, commonly known as air, retained by Earth's gravity, surrounding the planet Earth and forming its planetary atmosphere.The 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 … geosphere. 3. Elements in Space. • Nitrogen and oxygen are the most common elements in the atmosphere. Estimates of elemental abundance are difficult because (a) the composition of the upper and lower crust are quite different, and (b) the composition of the continental … The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases. All animals and many microorganisms need oxygen to fuel their growth (and metabolism). What element composes most of Earth’s crust? 9 years ago. In addition, Earth's atmosphere contains traces of dust particles, pollen, plant grains and other solid particles. However, we must also consider the relative abundances of O and N over … Oxygen is the third-most abundant element in the universe. Argon, an inert gas, is the third most abundant gas in the atmosphere. It provides us with the oxygen we need to stay alive. It burns with a white light and is the eighth most abundant element in Earth’s crust. 30 seconds . Together, they’ll provide the most comprehensive view to date of this critical layer of Earth’s upper atmosphere. Jet streams are extremely important to the airline industry.

It also dilutes oxygen and stops burning at the surface of the Earth. The most abundant element in the Earth's crust is oxygen, making up 46.6% of Earth's mass. The greenhouse effect is necessary for life on Earth. pressure Force applied uniformly over a surface, measured as force per unit of area. The order of elements by volume-fraction (which is approximately molecular mole-fraction) in the atmosphere is nitrogen (78.1%), oxygen (20.9%), argon (0.96%), followed by (in uncertain order) carbon and hydrogen because water vapor and carbon dioxide, which represent most of these two elements in the air, are variable components. Explain Why are the compositions of Earth’s crust and oceans different? The atmosphere is the mixture of gas molecules and other materials surrounding the earth. The abundance of elements in Earth's crust is shown in tabulated form with the estimated crustal abundance for each chemical element shown as mg/kg, or parts per million (ppm) by mass (10,000 ppm = 1%). The atmosphere’s most abundant greenhouse gases are carbon dioxide , water vapor, and methane. The composition of the atmosphere, among other things, determines its ability to transmit sunlight … The Earth’s atmosphere is the relatively thin layer of gases that surround the planet. (And this … Oxygen also is the most abundant element in Earth's crust, yet Earth's crust is not a gas. All of the other elements are relatively rare. During the day, the land gets heated up much faster than the sea. Q. radioactive decay A process by which an element … For a broader view, GOLD will make global-scale observations of Earth’s upper atmosphere, including the ionosphere, from an altitude of 22,000 miles – gathering … what two elements make up most of the earths atmosphere? The light spectrum observed from this distant star shows a. answer choices . 0 0. Anonymous. A pure substance made of two or more elements CHEMICALLY combined.
