What is the meaning of lava plateau?
Lava plateaus are landforms created by volcanic activity. When shield volcanoes erupt, magma flows from the Earth’s mantle through fissures in the crust. These flows, which are primarily made up of basalt, harden into layers or ‘flows,’ which build up over time to create the lava plateau.
What is lava plateau class 6?
Ans: Lava plateaus are formed by highly fluid (runny) basaltic lava during numerous successive eruptions through numerous vents without violent explosions (quiet eruptions). These eruptions are quiet because of low viscosity of lava and contains small amount of trapped gases.
How are lava plateau formed give one example?
Lava plateaus are formed when landscape is covered by lava and volcanic ash The huge volume of volcanic materials needed to produce a lava plateau comes from an event known as a flood basalt eruption, an eruption extreme in both extent and duration.
Where is the volcanic plateau?
The Volcanic Plateau stretches from the Bay of Plenty coast to south of Ruapehu. The region’s landforms have been formed by volcanic activity, which has produced volcanoes, massive calderas occupied by lakes, hot springs, mud pools and steaming mountainsides.
What is plateau and types?
A plateau is a flat, elevated landform that rises sharply above the surrounding area on at least one side. There are two kinds of plateaus: dissected plateaus and volcanic plateaus. A dissected plateau forms as a result of upward movement in the Earths crust.
What are plateaus called?
In geology and physical geography, a plateau ( /pləˈtoʊ/, /plæˈtoʊ/, or /ˈplætoʊ/; French: [pla.to]; plural plateaus or plateaux), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side.
What is plateau short?
A plateau is a flat, elevated landform that rises sharply above the surrounding area on at least one side. Plateaus occur on every continent and take up a third of the Earths land. They are one of the four major landforms, along with mountains, plains, and hills.
What is plateau class 6th?
A plateau is an elevated flat land. It is considerably higher than the surrounding area. It is a flat-topped table land, standing above the surrounding area.
How are volcanic plateaus formed?
A volcanic plateau is formed by numerous small volcanic eruptions that slowly build up over time, forming a plateau from the resulting lava flows.
How is a plateau formed?
Many plateaus form as magma deep inside the Earth pushes toward the surface but fails to break through the crust. Instead, the magma lifts up the large, flat, impenetrable rock above it. Geologists believe a cushion of magma may have given the Colorado Plateau its final lift beginning about ten million years ago.
What is an example of lava plateau?
Lava or volcanic plateaus are the plateau that occur in areas of widespread volcanic eruptions. These layers of lava sheets form lava or volcanic plateaus. The Antrim plateau in Northern Ireland, The Deccan Plateau in India and the Columbia Plateau in the United States are examples of lava plateaus.
What is called plateau?
A plateau is a flat, elevated landform that rises sharply above the surrounding area on at least one side. They are one of the four major landforms, along with mountains, plains, and hills. There are two kinds of plateaus: dissected plateaus and volcanic plateaus.
What does the word lava plateau mean?
lava plateau. [ ‘lä·və pla,tō] (geology) An elevated tableland or flat-topped highland that is several hundreds to several thousands of square kilometers in area; underlain by a thick succession of lava flows.

What is the process that creates lava plateau?
Plateaus can be formed by one or more processes, including erosion, upwelling of magma , and extrusion of lava . They can either be created when magma is pushed upwards but does not break through the earth’s surface but rather raises a section of the crust.
What is an example of a lava plateau?
Lava plateau. The Pajarito Plateau in New Mexico, USA is an example of a volcanic plateau. Lava plateaus are formed by highly fluid (runny) basaltic lava during numerous successive eruptions through numerous vents without violent explosions (quiet eruptions).
What is Plateau and how are plateaus formed?
A plateau is the raised land with a flat top and steep slope on at least one side. Plateau can is formed by the erosion of surrounding areas by rivers, flooding, and glacier activity . An uplift of land can occur from the pressure of a large magma chamber layers of rock. It is called a high plain or tablelands, it is an area of high land.
