Antarctica is the most southern continent on the planet Earth. It can be located below the country of Australia in the Antarctic region of the southern hemisphere. It is the fifth largest continent in area on the planet. Approximately 98% of Antarctica is covered with ice that in on average is 1.6 kilometers (1 mile) thick. Antarctica is considered to be a desert as it only gets a small amount of rain per year. It is inhabited by cold climate wildlife such as penguins, seals, roundworms and mites. Anywhere from 1,000 to 5,000 people reside in Antarctica yearly in the research stations and science facilities that are spread across the continent. Antarctica is the highest, driest, coldest and windiest continent on the planet.
Acid rain is classified as any form of precipitation (rain, snow, fog, hail) that has a pH of 4 or lower. It is primarily a result of air pollution. Particular gases released into the atmosphere react with the water particles in clouds and combine to make a very weak form of acid. Acid rain can have harmful effects on plant life, water supplies and aquatic life and some forms of infrastructure. Acid rain is not acidic enough to burn your skin upon contact. The acid that is formed in the atmosphere can also fall as acidic dust and pollute the soil many thousands of kilometers from the source of the pollution.
To understand what causes an earthquake you first need to understand that the surface of the earth is made up of a number of rigid tectonic plates. These tectonic plates are in constant motion and are slowly drifting across the magma that makes up the Earth’s core. These plates cover the entire surface of the Earth and as they are moving they often rub up against one another, sink under one another or spread apart from one another.
The name global warming is given to the phenomenon where there is an increase in the temperature of the Earth’s surface. This is typically due to the collection of greenhouse gases, carbon dioxide, water vapor, nitrous oxide and methane in the Earth’s atmosphere. These gases trap excess heat and light from the sun that would otherwise escape back into space. While Earth’s atmosphere is design to do this the excess gases have intensified this effect causing a warming of the Earth. Global warming was recognized by scientists and meteorologists in the mid 20th century. Since then investigations have been undertaken to determine what is causing the buildup of greenhouse gases in the atmosphere. The increase in these gases can be traced back to human activities such as burning fossil fuels and deforestation.
The amount of electricity a house uses depends largely on how many people live in the houses and the number of appliances in the house that draw electricity. It is also important to remember that many of the electrical items that we own are on standby mode which continues to draw power even when “off.” Certain seasons also require us to use more electricity to power heating and cooling appliances.
Global warming is the names given to the increase in the Earth’s surface temperature. It is caused by the collection of greenhouse gases, carbon dioxide, water vapor, nitrous oxide, and methane, in the Earth’s atmosphere. The Greenhouse Effect is where excess heat and light form the sun is trapped within the earth’s atmosphere instead of escaping into space. The term Global Warming was first coined by scientists and meteorologists in the mid 20th century. Since then investigations have been undertaken to determine what is causing the buildup of greenhouse gases in the atmosphere. The increase in these gases can be traced back to human activities such as burning fossil fuels and deforestation.
Recycling is the act of turning something old or used into something new. The recycling of glass, paper, aluminum, plastic and green waste has been going on for years. We are now starting to recycle items such as computers, mattresses, tetra packaging, tires and almost any product you can think of. Recycling is one of the keys to a sustainable future. But how exactly does recycling your old newspapers and milk bottles help the environment?
Biodiversity is a word that is used a lot in scientific circles and environmental groups. Research is often carried out to determine the biodiversity of a particular area or the planet. In fact the year 2010 is the International Year of Biodiversity. But what exactly does biodiversity mean?
Recycling is the process of changing old and used products into new products to reduce pollution and prevent the waste of useful material. Here are some to main reasons why recycling is very important.
Earth Day (April 22) is a day set aside to promote awareness and appreciation for the Earth’s environment. But when was the first Earth Day celebrated? This post will answer that question and then look at a few interesting facts about Earth Day.
