Air pollution is the introduction of chemicals‚ particulates‚ biological materials‚ or other harmful materials into the Earth’s atmosphere‚ possibly causing disease‚ death to humans‚ damage to other living organisms such as food crops‚ or the natural or built environment. The atmosphere is a complex natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s

Avalanches Have you ever seen or heard about avalanches before? It is an incredible site to see in pictures‚ but it’s terrifying in real life. Avalanches suffocate‚ crush‚ and kill hundreds of people each year. They happen suddenly‚ so watch out. . . Sluff vs. Slab There are two main kinds of avalanches‚ Sluffs and Slabs. They are similar in some ways and different in others. A Sluff avalanche forms when a weak layer of snow is piled on the top and the hard snow is on the bottom. The weak

Dynamic Earth Has the Earth been static since the beginning of time? Well‚ Earth hasn’t been moving vigorously but it is changing at a steady rate. New geological features‚ rock formations‚ and locations of plates all rise and demolish some in a lifetime and others over a span of millions of years. Earth is dynamic; it constantly progresses and doesn’t rest. Through the churns and molds‚ the twists and turns‚ Earth is active because of plate tectonics and the rock cycle. The ideas

Essay on Earthquake The usual phenomena recorded in well-known earthquakes are first a trembling‚ next one or more serve shocks‚ and then a trembling which gradually dies away. In most cases‚ each shock lasts only a few seconds‚ but the trembling that follow may continue for days. Weeks or even months. Noises of various kinds usually accompany an earthquake. They have been likened to the growling of storm‚ the growling of thunder‚ the clanking and are not accompanied by these noises. At

Rockfalls are a very dangerous phenomenon. In class we learned that anything that is not at a 30 degree angle or less is unstable‚ and will tend to fall. This is how rocks and any type of earth falls. At the Yosemite National park‚ there is a crack in a cliff that measures 19 meters long‚ that is a little over 62 feet long. This crack fluctuates in width by about a centimeter from day to day. The widest the crack ever has gotten is 12 centimeters. Scientist can measure this width by using a device

A metamorphic Rock can be formed by simply being under the earth’s surface‚ being exposed to extremely high temperatures and a huge amount of pressure from the layers of rock above. These rocks can be formed by tectonic processes‚ some which include‚ continental collisions (this is a process that causes friction‚ distortion and horizontal pressure). These rocks can also be formed when rock becomes heated rapidly by the intrusion of a hot molten rock‚ (called magma) and it comes from the earth’s interior

Julia Rabbia Geological Features Plate tectonics theory‚ which is the modern theory of the motions of Earth’s layer‚ explains how geological features‚ such as mountain ranges‚ continents‚ and bodies of water move and form. An important aspect of plate tectonics theory is that the outer layer of the earth is divided into plates which move across the earth’s surface. “These plates move relative to each other‚ typically at rates of 2-4 inches per year. As the plates move‚ they interact along their

The causes of acid rain are because of the emissions of sulphur dioxide and nitrogen oxides in the atmosphere. This is a result of pollution; sulphur dioxide primarily the result of industrialisation and coal fired power stations‚ and nitrogen oxides produced mainly due to car exhaust fumes. These either form wet or dry deposition‚ and the effects we can see today. It could be argued that once that the human race has used up all of the planets coal reserves‚ the problem of acid rain would disappear
