A geographic information system is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. The key word to this technology is Geography – this means that some portion of the data is spatial
With the recent technologies and scientific innovations we have now on studying and providing detailed analyses of the polar ice cores, it is roughly estimated that we could profile the ancient climate the Earth had in a time period as early as 800,000 years in order to explain the most recent climate change.
Answer:
Option (4)
Explanation:
Seismic P and S waves are generated during an earthquake that has the potential to propagate through the interior of the earth. P waves are also known as the primary waves and they move in a compression and extension way in their direction of propagation. S waves are shear waves. This P waves travel faster than the S waves and can travel in both solid as well as in liquid. Whereas the S wave can travel only through solids. They get absorbed when they reach the core-mantle boundary. These two waves are helpful in determining the epicenter of an earthquake by recording the arrival of these waves.
Hence, the correct answer is option (4).
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:
C. Constant burning of fossil fuels at power plants increases carbon dioxide concentrations in the atmosphere, resulting in faster input of carbon into the atmosphere than the ocean and land can take up.
Explanation:
Nutrient cycling is the process that allows for a continuous and balanced exchange of nutrients between the earth, living beings and the atmosphere. This exchange allows life on earth to be allowed and managed. An imbalance in this exchange can cause very harmful effects that damage the entire system that the earth maintains.
An example of this is the imbalance caused by the excess burning of fossil fuels. That's because the constant burning of fossil fuels in power plants increases concentrations of carbon dioxide in the atmosphere, resulting in a faster entry of carbon into the atmosphere than the ocean and land can absorb.
