Answer:
Two possible reasons for the massive extinction at the end of the Paleozoic Era are an asteroid collision and massive volcanic eruptions.
Explanation:
The massive extinction that occurred at the end of the Paleozoic Era is the biggest extinction from what is known so far. The majority of the species died out, and whole families of animals and plants were wiped out of the face of the Earth. It was only small and highly adaptable organisms that managed to survive and give rise to the later life-forms.
The two possible reasons for this massive extinction are an asteroid impact and massive volcanic eruptions. An asteroid collision would have created drastic changes in a matter of minutes and hours, with effects lasting for a long period of time, thus eliminating the majority of the life. Massive volcanic eruptions, with the Siberian super-volcano being the prime candidate, may have caused enormous amounts of carbon dioxide and sulfur dioxide to end up in the atmosphere, thus rapidly changing the living conditions on the planet.
Answer:
B. The Channel Tunnel connecting the United Kingdom and France reduced travel time between these nations
E. Land has been cleared to make room for France's famous vineyards
F. A highway through Mount Blanc connects Italy and France
Explanation:
One of the five themes of geography is the human-environmental interaction. The human-environmental interaction basically means that the humans and the environment interact with each other and affect each other, sometimes in positive manner, sometimes in negative manner. There are many examples for this geographic theme across the globe.
The Channel Tunnel between the UK and France is an underwater tunnel. Its purpose is to make the traveling easier and faster between the two nations. It has been built in the sea waters, and fortunately it is not having any negative impacts on the environment.
France is one of the biggest producers of vine in the world. In order to have the amount of grapes needed for France to produce lot of vine it needs lot of agricultural land. This has been accomplished by clearing the land from the wild vegetation over time. While this has had a very positive impact on the economy of France, it has had very negative effect on the wildlife as it has totally ruined the habitat for lot of species.
Italy and France are separated by a massive mountain range, the Alps. The Alps are very large and very high, but nonetheless the humans managed to find ways to build highways through them despite all the difficulties. The highways are state of art through the Alps, and they are very useful for the countries in the region as these highways connect them, and not making them isolted. It has not been so great for the environment though, as lot of changes have been done to the mountain range, and every day there's thousands of animals that die on the highways.
It would be about 20 degress hotter in the summer and 20 degress colder in the winter.
2 tectonic plates meet at the regions edge
Explanation:
The "doldrums" is a descriptive adjective for the corridor from around Earth closer to the equator when ships can become stuck in windless seas. In the horse elevations, where even the air moves down to towards the Earth's surface, the increasing jet stream eventually subsides.
