Вступ The Greenhouse Effect The greenhouse effect is a naturally occurring process that aids in heating the Earth's surface and atmosphere. It results from the fact that certain atmospheric gases, such as carbon dioxide, water vapor, and methane, are able to change the energy balance of the planet by absorbing longwave radiation emitted from the Earth's surface. Without the greenhouse effect life on this planet would probably not exist as the average temperature of the Earth would be a chilly -18°

Nitrogen is a big part of Earth’s atmosphere. In fact, nitrogen makes up 78 percent of our air. Nitrogen is extremely important in living things. It forms the building blocks of life, because amino acids; constituent of proteins and nucleic acids; constituent of DNA (deoxyribonucleic acid), would not have existed without nitrogen.(1) We need proteins because they make up our skin and hair. Proteins also help us digest food. We get our nitrogen from plants, and plants get it from bacteria in the

Water pollution Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities. Introduction

The Greenhouse Effect Ashley 24/1/2013 The Greenhouse effect is a process that is naturally occurring on our planet. The reason it is a concern is many scientists believe the process is being changed because of our use of energy in the last 100 years or so. Most greenhouses look like a small glass house. Greenhouses are used to grow plants, especially in the winter. Greenhouses work by trapping heat from the sun. The glass panels of the greenhouse let in light but keep heat from escaping. This
