What is hotspot in geography?

A hotspot is a large plume of hot mantle material rising from deep within the Earth. A line of volcanoes develops as a plate moves over a hotspot, much as a line of melted wax forms as a sheet of waxed paper is moved slowly over a burning candle.

Where are hotspots located?

Hot spots are found in the ocean, and on continents. Often the hot spot creates a chain of volcanoes, as a plate moves across a relatively stationary mantle plume. The best example of a hot spot volcanic chain is the Hawaiian Islands.

How are hot spots formed?

A hot spot is fed by a region deep within the Earth’s mantle from which heat rises through the process of convection. This heat facilitates the melting of rock at the base of the lithosphere, where the brittle, upper portion of the mantle meets the Earth’s crust.

Why hotspot is called hotspot?

The company was sold to Deutsche Telecom in 2001, who then converted the name of the firm into “T-Mobile Hotspot”. It was then that the term “hotspot” entered the popular vernacular as a reference to a location where a publicly accessible wireless LAN is available.

What are some examples of hotspots?

Hispaniola is among the Caribbean islands comprising a biodiversity hotspot.

  • The Caribbean Islands.
  • The Atlantic Forest in Brazil.
  • Southeast Asia.
  • The Philippines.
  • The Horn of Africa.
  • Madagascar.
  • The California Coast.

Do hotspots move?

Hotspots are places where plumes of hot, buoyant rock from deep in the Earth’s mantle plow to the surface in the middle of a tectonic plate. They move because of the convection in the mantle that also pushes around the plates above (convection is the same process that happens in boiling water).

What are the features of hotspot?

How many hotspots are there in the world?

There are currently 36 recognized biodiversity hotspots. These are Earth’s most biologically rich—yet threatened—terrestrial regions. To qualify as a biodiversity hotspot, an area must meet two strict criteria: Contain at least 1,500 species of vascular plants found nowhere else on Earth (known as “endemic” species).
