Chapter 17 Vocab * Acid deposition- the settling of acidic or acid-forming pollutants from the atmosphere onto Earth’s surface. * Acid rain- Acid deposition that takes place through rain. * Aerosols- very fine liquid droplets or solid particles aloft in the atmosphere. * Air pollutant- gases and particulate material added to the atmosphere that can affect climate or harm people or other organisms. * Air pollution- the act of pollution the air‚ or the condition of being polluted

cycle is made up of 4 main parts: Evaporation and transpiration‚ condensation‚ precipitation‚ and accumulation. There are a few more processes to include. 11. troposphere- where weather froms. stratosphere- where the protective ozone layer is. Mesosphere- shooting stars blaze. Thermosphere- the temperature rises. Exosphere- the farthest layer 12. Geopshere- all the rocks and hard parts of earth. Hydrosphere- all of earths water. Biopshere- all living things. atmosphere- the blanket of gases surrounding

“Let us give the children a vision of the universe‚” Wrote Maria Montessori in To Educate the Human Potential. “The universe is an imposing reality and the answer to all questions.” Montessori observed firsthand children’s eagerness to understand themselves‚ their world‚ and their place in it. It was her hope that Cosmic Education would allow children to grow into responsible sons and daughters of the great human family with the understanding‚ ethics and self-knowledge needed to transform the

roughly 6.5-30 miles from the earth ’s ’ surface. The air on this region is much less dense than in the troposphere‚ and it ’s a lot drier. The stratosphere is the area that contains the majority of the ozone layer. Past the stratosphere is the mesosphere which extends to 50 miles above the planet. The last region is the thermosphere. The thermosphere ’s outermost edge is roughly 600 miles above the surface of the earth. Beyond it‚ the airless vacuum of space begins. Oxygen is made up of two

Atmosphere Homework Describe the composition of the air Air is a mixture of gases and aerosols that compose the atmosphere surrounding Earth. The primary gases of air include nitrogen (78%) and oxygen (21%). Trace gases and aerosols make up the remaining 1% of air. The trace gases include the noble gases argon‚ neon‚ helium‚ krypton and xenon‚ hydrogen and the greenhouse gases. The aerosols are solid or liquid particles having diameters in the region of 0.001 to 10 microns‚ and include dust

The layers of Earth How do scientists know what is in the center of the earth? How can we know what the core of the earth is made of‚ if scientists have never studied any materials from a depth below 7.5 miles? Earth is approximately 4.6 billion years old‚ and over this time period‚ many things have changed inside and out. The formation of our planet is quite amazing. Earth consists of multiple layers. The three most distinct or main layers are the core‚ mantle and crust. The inner portion is

ultraviolet rays will reach to the lower atmosphere and its temperature will rise to that extent that the biological furnace of the biosphere will turn into a blast furnace. Formation of Ozone The atmospheric oxygen absorbs UV radiation in the lower mesosphere at < 240nm and Photo dissociates into two oxygen atoms. One of these oxygen atoms combines with 02 of upper stratosphere forming 03. Ozone is also capable of absorbing short wavelength UV radiations releasing oxygen atom. Reactions: 02 + hv
