DMPQ: What are the challenges faced by the fisheries sector in India?

The sector suffers from low-scale, stagnating yields of inland and freshwater aquaculture, and poor infrastructure such as cold storage facilities, leading to an estimated 15-20 per cent post-harvest loss. The access to quality seed and feed for fish farming coupled with inadequate availability of credit makes the poor fisher communities not to invest in fish … Read more DMPQ: What are the challenges faced by the fisheries sector in India?

The total fish production has nearly 65% contribution from the inland sector and rest form marine fishing.  Fish and fish … Read more DMPQ: Give a overview of the fisheries sector in India.

DMPQ: What is upwelling? Explain with an example. (GEOGRAPHY)

: Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”   Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to … Read more DMPQ: What is upwelling? Explain with an example. (GEOGRAPHY)

DMPQ: What are tides? How they are generated ? Explain different types of tide.

Tides are great bulges of water caused by the gravity of the moon and the sun. Attracted by gravity, these bulges move around the earth’s ocean, causing water level to rise and fall. There are two main tides that are higher or lower than average. They occur twice monthly and are called neap and spring … Read more DMPQ: What are tides? How they are generated ? Explain different types of tide.

DMPQ: . Interlinking of rivers is seen as a viable option to address the issue of water scarcity. Do you think interlinking of rivers is a full proof solution? (ENVT.)

Negatives of Interlinking of rivers: This entails environmental cost. Interlinking would destroy water bodies as each river has unique flora and fauna based on its ecology. Mixing of waters will adversely affect this uniqueness, producing unforeseen consequences. Interlinking will lead to submergence of forest. This will worsen climate change. Forest, which act as carbon sinks … Read more DMPQ: . Interlinking of rivers is seen as a viable option to address the issue of water scarcity. Do you think interlinking of rivers is a full proof solution? (ENVT.)

DMPQ: Give an account on the compositions of atmosphere. (geography)

The atmosphere is made up of different types of gases, water vapors and dust particles. The composition of the atmosphere is not static. It changes according to the time and place.   Water vapor is unique in that its concentration varies from 0-4% of the atmosphere depending on where you are and what time of … Read more DMPQ: Give an account on the compositions of atmosphere.

DMPQ: What are fronts? Name the different type of fronts. (Geography)

When two large air masses meet, the boundary that separates them is called a front. Fronts represent fairly abrupt transitions between two large air masses.  This means that when two different bodies of air come together, they do not readily mix. Rather, each body of air will retain its individual properties, and a boundary forms … Read more DMPQ: What are fronts? Name the different type of fronts. (Geography)
