The Rift Valley was formed by violent subterranean forces that tore apart the earth's crust.
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.
Answer:
To the east, the North American plate shares the Mid-Atlantic Ridge with the Eurasian plate. This divergent margin, offset throughout by transform faults, began spreading approximately 180 Ma ago, opening the North Atlantic Ocean. Evidence of Mesozoic juvenile crust formation in New England can be correlated with the event.
Explanation:
The San Andreas transform boundary between the Pacific and North American plate originates from the shallow, oblique subduction by the North American plate of the Monterey microplate
The Monterey-Pacific ridge stopped spreading and Monterey accreted to the Pacific plate. As a result, the Pacific plate’s motion with respect to the North American rotated, transforming a network of shallow faults into dextral transform faults
