There are several reasons for this. First, the mountain topography in Karnataka is broader than the narrow topography of the Ghats in Maharashtra. Due to the greater width of the mountains, the rain bearing winds have to necessarily travel a longer distance and have more time for the drops to coalesce and precipitate as rainfall, … Read more DMPQ: Western Ghats in Karnataka receive more monsoon rainfall than Maharashtra and Kerala.Explain

Geysers are fountains of hot water and superheated steam that may spout up to a height of 150 feet from the earth beneath. The phenomenon are associated with a thermal or volcanic region in which b the water below is being heated beyond boiling point. The jet of water is emitted with an explosion, and … Read more DMPQ: Explain ‘Geysers’ and ‘Hot springs’?

The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent. While Wegener was alive, scientists did not believe that the continents could move. Alfred Wegener proposed that … Read more DMPQ: What is continental drift theory? Write down the evidence for continental drift?

Sedimentary or detrital rocks :   They Formed as a result of denudation (weathering and erosion).These deposits through compaction turn into rocks. This process is called lithification. Sedimentary rocks Cover 75 per cent of the earth’s crust but volumetrically occupy only 5 per cent. They are layered or stratified of varying thickness. Example: sandstone, shale etc. … Read more DMPQ: What are sedimentary rocks? What are the its different types? List down the features of sedimentary rocks.

A fissure vent, also known as a volcanic fissure or eruption fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity. The vent is often a few meters wide and may be many kilometers long. Chinook : It is a local winds in steppe region. On the eastern slopes of the Rockies in Canada and U.S.A. a … Read more Please gave an account of the following in 50 words. a) fissure vent b) Chinook c) Fohn

An earthquake is the shaking or trembling of the earth’s surface, caused by the sudden movement of a part of the earth’s crust. The majority of earthquake occur at the point junction of major tectonic plates. The highly active regions are Pacific rim belt, Alpine belt , along oceanic ridges. The distribution is summarised as … Read more DMPQ: Give an account on the Distribution of Earthquake potential zone in the world.

Composite lava are highly viscous with a high melting point. They are light colored and have low density, and have a high percentage of silica. They flow slowly and seldom travel far before solidifying. The resultant cone is therefore steep sided.  The rapid solidifying of lava in the vent obstruct the flow of the out-pouring … Read more DMPQ: Differentiate between the Composite and the shield Lava.

Most known volcanic activity and the earthquakes occur along converging plate margins and mid-oceanic ridges. There is a strikingly close agreement between volcanic and earthquake zones of the earth. The major regions of volcanoes around the world are: Pacific ring of fire:  Pacific Ring of Fire’ is estimated to include two-thirds of the world’s volcanoes.  The major regions … Read more DMPQ: Distribution of volcanoes around the world.

An earthquake is the shaking or trembling of the earth’s surface, caused by the sudden movement of a part of the earth’s crust. They result from the sudden release of energy in the Earth’s crust that creates seismic waves or earthquake waves.   Causes of the earthquake are as follows:   Sudden slipping of rock … Read more DMPQ: What is Earthquake?

( in answer writing when such kind of explanation is asked follow this approach) Distribution:     Lies in the interior of the earth crust. They basically lies in the zone of  westerly wind belt. Grasslands are practically treeless due to continentality. They are called by different names in different parts of the world Prairies North … Read more DMPQ: Discuss the steppe type of climate.
