The "lost city" of Pompeii was an amazing disclosure in 1738. From that point forward, a huge number of visitors have set out to Italy to see this mind blowing disclosure of a city finished covered in fiery debris very nearly 2000 years back. The essential concern confronting students of history and archeologists today is saving this site and protec±ng it from visitors and the components.
Answer:
Yes
Explanation:
The General Mining Act of 1872 , needs to be reformed because there is a clause in it that there will be no protection of environment. This cannot be justified seeing the present day scenario as environment has come under huge stress due to anthropogenic activities including mining. Sustainable development is more important than increasing economy. Environment protection will also help in economy boost in a long run by reducing the costs of rejuvenating the damaged ecosystem in future.
Answer:
Explanation:
The three main types of volcanoes are as follows:
1. Composite volcanoes: These are also called as strato volcanoes. These are steep and formed by the layers of ashes and lava. The eruption from these volcanoes is in the form of pyroclastic flow. The pyroclastic flow is in the form of superheated mixture which consists of rock dust, ash, and hot steam. These volcanoes can rise above the 8000 feet. These are found in the destructive plate margins. Example of these volcanoes include the Mount Fuji in Japan.
2. Shield Volcanoes: These volcanoes are low and they have gentle sloping sides. These are formed by the layers of lava. Their eruption of lava is non-explosive. These produces the fast flowing fluids that can flow to many miles. These can destroy the nearby surrounding regions can cause injury and even death. These volcanoes are found in the region of constructive boundaries and also at the volcanic hotspots. The examples of shield volcanoes include the Maunaloa on Hawaii.
3. Dome volcanoes: These are also called as acid lava cones as these emit acid which is much thicker than that of the lava. These have steeper sides as compared to the shield volcanoes. The lava is thick and sticky as a result of this it cannot flow to far region and it cools and solidifies. The example of dome volcanoes include the Puy de Dome of Auvergne, France.
Continental drift is the name of this theory.
