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? List down the causes of 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.

The savanna or sudan climate is a transitional type of climate found between the equatorial forest and the trade winds hot deserts. It is confined within the tropics and is best developed in the sudan where the dry and wet seasons are most distinct, hence its is named sudan climate. Llanos in oronocco basin and … Read more DMPQ: Explain the Savanna type of climate

A glance at the world map reveals that most of the desert region is on the western part of the continent for example. Mohave desert in North America, Atacama in Southern America, Namib, Sahara in Africa , Arabian in west Asia. The reasons for such homogeny are: The hot desert lie astride the Horse latitudesor … Read more DMPQ: why desert are on the western margins of the continent?

Climate is the average weather conditions of large area. According to the koeppen system of classification , the world is divided into five climatic groups and 13 climatic types based on the temperature, precipitation and vegetation. The notable characteristics of Monsoon type of climate are as follows: The climate is divided into distinct 4 seasons. … Read more DMPQ: Discuss the features of the Monsoon type of climate.

Tea is an evergreen plant that mainly grows in tropical and subtropical climates. It is thought to have originated in East Asia somewhere between China and Burma. The geographical factors required for Tea cultivation are: Tea grows in a moderately hot and humid climate . Moring fog and low temperature is necessary for the growth … Read more DMPQ: Discuss the factors associated with tea cultivation.

El-nino is the classical phenomenon where warming of Pacific ocean takes place near the western coast of Peru and Equador. It occurs at every 3-4 years. It weakens the trade winds and changes in southern oscillation , thereby affects the rainfall pattern across the world. Southern oscillation: Southern oscillation is the alternating of sea level … Read more DMPQ: What is El Nino and southern oscillation and How it affects the Indian Monsoon.

Seismic waves are generated due to the release of the energy during an earthquake. They behave differently in different physical mediums and hence provide a good idea how the interior of earth must be. Broadly there are three types of seismic waves: Primary waves: (P) – Waves are longitudinal waves. i.e. The motion of particles … Read more DMPQ: what are seismic waves? Explain the different type of seismic waves?
