The changes in our environment

Reports To ask less of the planet, we ask more of ourselves.

The changes in our environment

Lake A lake from Latin lacus is a terrain featurea body of water that is localized to the bottom of basin. A body of water is considered a lake when it is inland, is not part of an oceanand is larger and deeper than a pond. Natural lakes on Earth are generally found in mountainous areas, rift zonesand areas with ongoing or recent glaciation.

Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world, there are many lakes because of chaotic drainage patterns left over from the last Ice Age.

The changes in our environment

All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them. Pond A pond is a body of standing watereither natural or man-made, that is usually smaller than a lake.

A wide variety The changes in our environment man-made bodies of water are classified as ponds, including water gardens designed for aesthetic ornamentation, fish ponds designed for commercial fish breeding, and solar ponds designed to store thermal energy.

Ponds and lakes are distinguished from streams by their current speed. While currents in streams are easily observed, ponds and lakes possess thermally driven micro-currents and moderate wind driven currents. These features distinguish a pond from many other aquatic terrain features, such as stream pools and tide pools.

Atmosphere, climate and weather[ edit ] Atmospheric gases scatter blue light more than other wavelengthscreating a blue halo when seen from space.

Lightning is an atmospheric discharge of electricity accompanied by thunderwhich occurs during thunderstorms and certain other natural conditions. The remaining gases are often referred to as trace gases, [12] among which are the greenhouse gases such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone.

Filtered air includes trace amounts of many other chemical compounds. Air also contains a variable amount of water vapor and suspensions of water droplets and ice crystals seen as clouds.

What is Science?

Many natural substances may be present in tiny amounts in an unfiltered air sample, including dustpollen and sporessea sprayvolcanic ashand meteoroids. Various industrial pollutants also may be present, such as chlorine elementary or in compoundsfluorine compounds, elemental mercuryand sulphur compounds such as sulphur dioxide [SO2].

The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes. These layers are mainly determined by whether temperature increases or decreases with altitude. From highest to lowest, these layers are: The top of the thermosphere is the bottom of the exosphere, called the exobase.

It is the layer where most meteors burn up upon entering the atmosphere. The troposphere is mostly heated by transfer of energy from the surface, so on average the lowest part of the troposphere is warmest and temperature decreases with altitude. The tropopause is the boundary between the troposphere and stratosphere.

Other layers Within the five principal layers determined by temperature are several layers determined by other properties. The ozone layer is contained within the stratosphere. It forms the inner edge of the magnetosphere. The homosphere and heterosphere: The homosphere includes the troposphere, stratosphere, and mesosphere.

The upper part of the heterosphere is composed almost completely of hydrogen, the lightest element. Effects of global warming[ edit ] The Retreat of glaciers since of Aletsch Glacier in the Swiss Alps situation inanddue to global warming.

Effects of global warming The potential dangers of global warming are being increasingly studied by a wide global consortium of scientists. These scientists are increasingly concerned about the potential long-term effects of global warming on our natural environment and on the planet.

It is clear the planet is warming, and warming rapidly. The most recent report from the Intergovernmental Panel on Climate Change the group of the leading climate scientists in the world concluded that the earth will warm anywhere from 2.

Some examples of recent collaboration to address climate change and global warming include: Another view of the Aletsch Glacier in the Swiss Alps and because of global warming it has been decreasing The United Nations Framework Convention Treaty and convention on Climate Change, to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.

A common solution is to adapt a static view neglecting natural variances to exist. Methodologically, this view could be defended when looking at processes which change slowly and short time series, while the problem arrives when fast processes turns essential in the object of the study.Below you will find a comprehensive list of new content, balance changes, and whatever else is included in the current PBE cycle!

Be aware that these changes are extremely tentative, there is a possibility that things you see below will be changed or even reverted prior to the live patch. Environmental Awareness - Naturalist Intelligence Environment is the area in which we live and thin layer of air that surrounds our planet that supports are the only kind of life that we know of that exists in our universe.

If we did not have our environment we could not exist. Every time a physical environment is changed, all the plants and animals in that environment must adapt to the changes or become extinct. Slow changes give living things time to adapt by the process of evolution over many generations. But we discount the fact that optimizing our environment to make better choices can make a large impact on our actions.

The changes we make may seem small initially. What is science? Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions.
