Catastrophic extinction would have been caused by a sudden, external event, such as the collision of the earth with an asteroid, or the eruption of a series of gigantic volcanoes. Gradual extinction would have been the result of changes in the earth's land mass and climate shifts. It could...
The aim of this article is to demonstrate the potential of selected cities for the development of geotourism whose subject of interest are phenomena that sometimes assume catastrophic dimensions for humans. The discussed issue has been illustrated with examples from Poland and the Czech Republic, showi...
Natural events like earthquakes, landslides, volcanoes, and floods are commonly called natural disasters but can have some positive effects on the habitats of animals, including humans. Explore examples of natural events and resulting changes to habitats, learn the pros and cons of natural events, ...
Volcanoes come in different sizes and shapes, and one of the biggest is that of the Caldera.Answer and Explanation: An eruption at Yellowstone would be the beginning of a large chaotic change for North America, eventually affecting the global climate. A 500-mile......
Volcanic gases are gases that have escaped or have been released from the Earth during volcanic activity. There are a number of...
The boundary between the mantle and the earth's crust or surface is called the Mohorovicic Discontinuity. People call it the Moho for short. When the earth experiences volcanic or tectonic activity, rocks from the mantle can spew through openings in rifts and volcanoes to change the face of th...
Byminombre— On May 21, 2009 Some cities are more prone to a natural disaster than others. It depends on the location. For example Miami Florida, and New Orleans Louisiana, are going to have more hurricanes and flooding, than let say Cleveland or Milwaukee. ...
Humans Impact On Climate Change Most of the blame for climate change over the years especially after the 1850’s has been placed on humans. As long as modern humans have roamed the earth, they have been upsetting the natural balance of the earth. People have did this by clearing areas of...
What Can Humans Do to Stop the 6th Mass Extinction? As in some other previous mass extinctions which were caused byglobal scale habitat destructionand losses either by volcanoes or meteorite impact, the current 6th mass extinction has also been highly affected by destruction of habitats. Finding ...
Apocalyptic volcanoes that caused global warming Something known as a hyperthermal event — a sudden warming of the planet — spelled doom for large segments of life on Earth on more than one occasion. These events have followed a predictable pattern: volcanic eruption, carbon dioxide release, glob...
