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?

It is the lower most layer of atmosphere. It extends up to 18km at equator, 13 km at midlatitude and about 8km at poles.It contains approximately 90% of the total mass of the atmosphere.The entire weather phenomenon takes place in this layer. It contains all the watervapour, dust particles, clouds etc. In troposphere the temperature … Read more DMPQ:Write a short note on Troposphere.

The wind blows from high pressure to low pressure. The wind at the surface experiences friction. In addition, rotation of the earth also affects the wind movement. The force exerted by the rotation of the earth is known as the Coriolis force. Thus, the horizontal winds near the earth surface respond to the combined effect … Read more DMPQ-. Discuss the forces affecting velocity and direction of wind.

Soil erosion : It is the process by which top layer of soil gets removed thus affecting the productivity by altering the structure of the soil. It is a natural process but human intervention has accentuated the rate of depletion of soil wealth. Soil Degradation:  It is a process through which qualitative degradation of soil … Read more DMPQ: What do you understand by the term soil erosion and soil degradation? what are the causes of soil erosion? List down the solution to curb soil erosion.

. Natural vegetation refers to a plant community that has been left undisturbed over a long time, so as to allow its individual species to adjust themselves to climate and soil conditions as fully as possible. Tropical evergreen forests  are found in the western slope of the Western Ghats, hills of the northeastern region and … Read more DMPQ-What is natural vegetation? Under what climatic conditions are tropical evergreen forests develop?

The following factors affect the distribution of temperature of ocean water: Latitudes The temperature of surface water decreases from equator towards the poles because the sun’s rays become more and more slanting and thus the amount of insolation decreases poleward accordingly. The temperature of surface water between 40°N and 40°S is lower than air temperature … Read more DMPQ- Discuss the factors affecting temperature distribution of Ocean water.

The stress on water scarcity can be gauge from the fact that 70% of the earth surface out of which only 3% is freshwater. 2/3rd of water is stored in glaciers and frozen lakes. Water scarcity is a condition when water is not available for consumption purpose easily. There are two types of water scarcity: … Read more DMPQ:What is water scarcity? Why earth is becoming water stressed?

A fault is a fracture in the earth’s crust due to tension force. It can also occur due tocompression in hard and brittle rocks. When there is tension the crust ruptures. One block is thrown upwards and the otherdownwards. The upthrown block is called Horst while the downthrown block is calledGraben. The line along which … Read more DMPQ-What is fault and list down the landforms formed due to fault. (GEOGRAPHY)

The systems developing in the mid and high latitude (35° latitude and 65° latitude in both hemispheres), beyond the tropics are called Frontal Cyclones or Wave Cyclones.According to polar front theory, the warm-humid air masses from the tropics meet the dry-cold air masses from the poles and thus a polar front is formed as a surface … Read more DMPQ- Frontal Cyclones.

It is a kind of irrigation method which saves water and fertilizer by allowing water to drip slowly to the roots of the plants, either onto the soil surface or directly onto the root zones, through a network of valves, pipes , emitters etc. It is done through narrow tubes that deliver water directly to … Read more DMPQ :What is drip irrigation? Explain the benefits of drip irrigation. ( Geography)
