Rising air currents take water, as vapor, up into the atmosphere; with the water form of "evapotranspiration," which is water transpired or from plants and that has evaporated from the soil. The cooler temperatures in the atmosphere cause it to condense in the clouds, which float around in the air until they fall from the sky as precipitation. Some precipitation falls as snow and can accumulate as hail, where it can stay, as ice crystals, for thousands of years. In warmer climates, snow melts, then warmer spring and summer months, and that water flows into streams and rivers, which eventually return it to the ocean, or into the groundwater, which eventually reach underground purifiers. Over time, the water continues to flow, some to return to the ocean, where the water cycle renews itself.
Rainwater and melted snow and ice that move too quickly to infiltrate the ground become runoff. Runoff replenishes the water on Earth's surface and helps to continue the water cycle. The next step in the cycle — evapotranspiration — returns water to the atmosphere. The Sun causes evaporation by heating liquid water on Earth's surface. Transpiration — the evaporation of water from pores in the leaves of plants — also releases water vapor into the atmosphere.
Due to the increase in greenhouse gases less solar energy is reflected back into space and more solar radiation is absorbed by the Earth causing the increase in ice and snow melting (Main & Ahlenius, 2011). With this background information the change of climate conditions such as, snow, rain, winds, and temperature is continuously happening all around the world and will continue to worsen in the future. A good indication of climate change is to look at the melting of glaciers and the Polar Regions as the Arctic is one of the fastest warming regions of the world. However, since the Polar Regions are so big and cold it would be impracticable for humans to live and carry out research there. Therefore, by using applications of remote sensing we can easily observe inaccessible areas from satellites to effectively monitor and map snow and ice cover in Polar
According to Merriam-Webster’s dictionary, the definition of snow is, “precipitation in the form of small white ice crystals formed directly from the water vapor of the air at a temperature below 32 degrees Fahrenheit.” Whereas, rain is defined as, “water falling in the drops condensed from vapor in the earth’s atmosphere.” There are many similarities and differences to rain and snow because of formation, destruction, weather apparel, and kids enjoyment. Another similarity between snow and rain is that they can both be very destructive. Large amounts of rainfall can produce floods. Floods can destroy homes, ruin farmer’s crops, and even loss of human life. Treacherous rainfalls are also able to produce landsides.
This is due to the friction that is created under the board. When going off a jump the snowboarder’s body will be fighting gravity that wants to pull him or her down. There are many different rotations that can be preformed off a jump like rotating 360 degrees in the air. For every rotation that does not make a complete circle (i.e. 180 degrees, 540 degrees etc.)
Some people think the melting of the glaciers are results of global warming. However, living here on Earth there have been warmer winters than usually, so in my own personal opinion I would agree with this theory. Although snow which is accumulated during the winter months is sure to melt and continue to add to the nation’s water. However, the warmer winter is a huge involvement in melting of glaciers which
Reading Assignment: Chronicles of Ice Summary: In Chronicles of Ice, Gretel Ehrlich sets out to “learn whatever lessons a glacier has to teach”, and to share what she has learned with us, as readers. The lesson the author relays to us is that the fate of the glacier is inextricably linked to that of the biological health of the Earth itself. Ehrlich uses the glacier as a device to show both cause and effect of the declining health of the Earth’s climate. The gases and particulate trapped in the ice provide the historical record of how industrialization has contributed to the rise in greenhouse gas levels and to the warming of the planet’s atmosphere and oceans. The resultant melting of glaciers, in turn, has far-ranging consequences for human populations across the globe.
ACID RAIN 1.) Define Acid Precipitation: Acid precipitation is a term used to describe any precipitation (rain, snow, fog) that has become acidic from reacting with compounds in the atmosphere. Acid precipitation forms when certain pollutants, most importantly sulfur dioxide and nitrogen oxides, combine with water in the atmosphere before falling to earth. Acid precipitation has a pH less than 5.6 which is the normal pH of rain. 2.)
What is acid rain? Acid rain or acid deposition is a broad term that describes any acidic form of precipitation from the atmosphere. There are two types of acid deposition: wet and dry. Dry deposition includes acidic particles, gases and dust that are deposited from the atmosphere, whereas wet deposition includes rain, hail, snow and fog. Unlike dry deposition, winds can blow wet deposition hundreds of miles away from the source of emission, making it an issue for everyone.
The deglaciation of ice sheets and glaciers, which happens when we enter a interglacial warming period, are important because they have an immense impact on the land structure and vegetation throughout our continent, as well as the rest of the world. The deglaciation of the Wisconsin Glacier caused the formation of the Great Lakes as well as Niagara Falls in New York. This melting of ice sheets also causes sea levels to rise which covers landforms. The water submerges bridges and passageways between continents that were used by animals which migrated from continent to continent. This prevents certain species of mammals and plants from returning back to their native land, which drastically changes the vegetation and habitat of certain areas.
