An earthquake is defined as the sudden shaking of the Earth's surface. Earthquakes are caused by the collision of tectonic plates in the Earth's crust. These plates ride over each other when instability is created in the crust due to the release of energy from the Earth's core.There are large earthquakes and small earthquakes. Earthquakes are measured using an instrument called Seismometer. The magnitude of an earthquake is represented on the Richter scale. On the scale, 3 or less is scarcely noticeable, and magnitude 7 or more causes damage over a wide area.The Great Chilean earthquake also known as the ... Read More

That's because the topsoil in most hill slopes is very thin, not exceeding a couple of feet. Such hill slopes can't be left bare of agricultural land in the plains because during the rainy season the water run-off is much faster on hill slopes than it is in the plains.As a result, any hill slope that doesn't have the protective cover of vegetation ...

Coming to the question - the Chinese are checking out Indian response to this blatant violation of international river-sharing laws. It's a serious challenge and the Indian ... Read More

Greenland is an island in the continent of North America.
