Your Questions About Whole House Solar Heating Systems

Henry Dover answers:

The sudden violence of volcanic eruptions causes catastrophe and devastation. Various notorious eruptions of volcanoes in the past, such as Mount Pelée, Tambora, Krakatau and Pinatubo have demonstrated the devastating impact of volcanic activity on nearby landscapes and communities. Many people got killed. A big number of people had to abandon their homes and land forever. Even the whole world’s climate was changed for a while as a result of an eruption!

These effects of volcanic eruptions are mostly the result of certain hazards. Volcanoes provide different hazards during an eruption. Each hazard poses different risks affecting different areas.

HOW DO VOLCANIC ERUPTIONS AFFECT SOCIETY?

Explosive volcanic eruptions pose both short-term and long-term hazards. Lava flows and lahars can wipe out the flanks of mountainsides. Volcanic ash can blanket the landscape for miles, and ash clouds can disrupt aircraft travel, such as the incident in 1989 when ash from Alaska’s Redoubt volcano temporarily disabled a passenger airplane. On longer time scales, eruptions can inject massive quantities of ash into the atmosphere, greatly reducing the solar heating of the Earth and potentially interrupting the global food supply for several years.

In 1991, mount Pinatubo in the Philippines erupted, and strong winds spread the aerosol particles from the plume around the globe. The result was a measurable cooling of the Earth’s surface for a period of almost two years. The role of natural hazards research and developing applications to mitigate the effects of disasters has global implications for reducing loss and saving lives.

Expected Accomplishments:

* Global inventory of active volcanoes
* Volcanic activity warning system
* Further define the relationship between deformation, seismicity, intrusions, and eruptions
* Forecasting of volcanic activity on progressively longer timescales

Practical Benefit to Society:

* Hazard mitigation due to improved volcanic activity warnings
* Advanced planning for effects on populations near volcanically active regions
* Detection of ash and plume products for warnings for airline industry

a lot of properties had been damaged because of unexpected volcanic eruptions…but we can still prevent the happenings by being completely prepared for any sudden changes in the environment. Be sure that you have goods in case your houses have melted because of the very hot lava coming out of the volcano…If ever you are near the volcano..For example if you are living below or next to it…and it’s going to explode…dont forget to save yourselves and you’re family..don’t ever think of bringing your whole house with you…because you might be too late and melt with your house…

So im warning all of you..be careful

2) “The answer to this question requires that we look at the origin of the solar system as a whole. Most scientists think that the solar system started as a huge cloud of dust and gas called a nebula. This nebula was very cold. This nebula started collapsing under its own gravity. As it collapsed, 99% of the material collected into the center (where the Sun would eventually form). The rest of the material collapsed down into a disk of material that swirled around the newly forming Sun. As the Sun began to form, the temperature at the center of our forming solar system rose. This controlled what materials were available for the formation of planets. Here in the inner solar system, the temperatures were too high for anything but rocky materials, iron, and nickel to form solids. As a result of this, we get the materials from which the inner planets were built. In the outer solar system, it was cold enough for water, methane, and ammonia to form solids. So, the planets of the outer solar system were built from these materials as were the rocky and metallic solids. With the addition of these ices were added to the mix, the planets of the outer solar system were able to grow big enough to grab and hold onto even the hydrogen and helium gas that was present in the solar nebula. Thus these planets grew into the gas giants. Comets from this part of the nebula also came into the inner solar system. It is from these comets that the inner planets (Earth included) got what volatiles they did. At first the earth was a hot glowing ball of white hot gases with a temperature that was millions of degrees Fahrenheit. This was caused by particles of gases being drawn together and compressed, giving off a lot of heat. This happened billions of years ago. Finally the earth cooled down. The ball of gas slowed down from spinning and the color changed from white to yellow to red to not giving off any light at all. The earth contracted, getting smaller and the gases changed to liquid as they cooled. Heavier materials drew to the center of the earth. The heavier liquid settled at the middle of the earth. As the earth cooled more, a solid crust formed over the over the liquid material. As the crust cooled, it got wrinkled and burst open in spots. Gradually cracks formed in the crust. Water that formed under the earth’s crust escaped from the cracks in the earth and soon water vapor formed above the earth. This lead to cloud formation. Larger droplets formed in the clouds and as they were pulled to the earth by gravity came the first rainfalls. The rain at first evaporated as soon as it hit the earth. Later, as the earth continued to cool, the rain stayed on to form lakes and oceans. At first the water was all fresh water, but as it had chemicals from the earth’s crust mix in, the water of the oceans became salty. At one time the earth was all water on its surface. Later pressure and heat in its center pushed up solid portions of the earth that became land forms. Sometimes the land would sink back down and other portions arise. About three million years ago, the earth cooled a great deal and great sheets of ice called glaciers covered its surface. As the ice spread over the land, it gouged great valleys, rivers and lakes into the earth. About 8000 years ago the last glaciers melted, with the earth finally looking more as it does today.”
