Earth magnetism is the property of earth behaving like a dynamo and showing magnetic property just like that of a magnetic bar. There are various theories behind this property. There is no valid reason for the cause of earth’s magnetism or why earth has giant magnetic field but there are some theory related to earth’s … Read more DMPQ- What is Earth Magnetism?

Temperate cyclones are also known as Extra-tropical cyclone where the term “Extra-tropical” signifies that this type of cyclone generally occurs outside the tropics with a latitude range between 30° and 60°. Characteristics of Temperate Cyclone (Extra-Tropical Cyclones) The Extra-Tropical Cyclones are storm systems emerging in the mid and high latitudes, away from the tropics. They … Read more DMPQ- Write a short note on Extra Tropical Cyclone.

They are places on Earth that are so cold that water is frozen solid. These areas of snow or ice, which are subject to temperatures below 32°F for at least part of the year, compose the cryosphere. The term “cryosphere” comes from the Greek word, “krios,” which means cold. Ice and snow on land are one part … Read more DMPQ- Write a short note on Cryosphere and how it affect our climate.

Environmental ethics is a branch of ethics that studies the relation of human beings and the environment and how ethics play a role in this.

A watershed is the geographic area through which water flows across the land and drains into a common body of water – stream, river, lake, or ocean. The watershed boundary follows the highest ridgeline around the stream channels which separates the water flow which may be basically rainwater, groundwater, water from melting snow etc. and … Read more DMPQ- Write a short note on watershed management.

The factors, which affect the distribution of temperature of ocean water are as follows: Latitude: The temperature of surface water decreases from the equator towards the poles because the amount of insolation decreases pole-ward.   Unequal distribution of land and water: The oceans in the northern hemisphere receive more heat due to their contact with … Read more DMPQ- What are the factors which affect the distribution of temperature of ocean water?

Tropical Cyclone Extra tropical cyclone It has thermal origin and derives its energy from the latent heat of condensation It has dynamic origin involving coriolis force and movement of air masses. The energy of a temperate cyclone depends on the densities of air masses. It is confined to 10o – 300 N and S of … Read more DMPQ- Differentiate between tropical and extra tropical cyclone.

Fold Mountains are commonly associated with continental crust. They are formed due to convergence between two continental plates or between an oceanic and a continental plate. This convergence happens at the convergent plate boundaries, also called as continental collision zones or compression zones. The convergence of two continental plates causes sediments between them to get … Read more DMPQ- Why Fold mountains are found along the continent margins.

A plain is a broad area of relatively flat land and is one of the major landforms on the earth surface. There are various types of Plains which are discussed as: Structural plains: relatively undisturbed horizontal surfaces of the earth. They are structurally depressed areas of the world that make up some of the most extensive … Read more DMPQ- What are Plains? What are different type of Plains?
