High-altitude adaptation in humans is an instance of evolutionary modification in certain human populations, including those of Tibet in Asia, the Andes of the Americas, and Ethiopia in Africa, who have acquired the ability to survive at extremely high altitudes. People living in high altitude can  inhale more air with each breath and breathe more … Read more DMPQ- What are the various high altitude adaptations in Humans?

Desert plants tend to look very different from plants native to other regions. They are often swollen, spiny, and have tiny leaves that are rarely bright green. Their strange appearance is a result of their remarkable adaptations to the challenges of the desert climate. Aridity is the sole factor that defines a desert and is … Read more DMPQ- Explain the adaptation of flora in desert type of climate to survive in extreme conditions.

High and low tides are caused by the Moon. The Moon’s gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. As the Earth rotates, your region … Read more DMPQ- How Tides are generated?

Trade winds: It is the wind blowing steadily towards the equator from the north-east in the northern hemisphere or the south-east in the southern hemisphere, especially at sea. Two belts of trade winds encircle the earth. These winds are called trade winds because of the fact that they helped the sea merchants in sailing their … Read more DMPQ- What are Trade winds? Mention the characteristics of Trade winds?

The cryosphere is the frozen water part of the Earth system. Beaufort Sea, north of Alaska. One part of the cryosphere is ice that is found in water. This includes frozen parts of the ocean, such as waters surrounding Antarctica and the Arctic.   There are places on Earth that are so cold that water … Read more DMPQ- What is Cryosphere?

Steppe Climatic region is also known as Temperate Grasslands. These grasslands are some of the most developed agricultural fields and are termed as grain baskets. Livestock ranching is another major activity carried out in these areas due to the availability of natural grasses. Distribution: Steppes are found in the continental interiors. They are usually found … Read more DMPQ-Write a short note on Steppe Climate Vegetation.

Radiocarbon dating is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. It can be used on objects as old as about 62,000 years. Here’s how it works. Radiocarbon dating relies on the carbon isotopes carbon-14 and … Read more DMPQ-Explain the working Principle of Carbon Dating Process.

a) Barrier reef: Barrier reefs are similar to fringing reefs in that they also border a shoreline; however, instead of growing directly out from the shore, they are separated from land by an expanse of water. This creates a lagoon of open, often deep water between the reef and the shore. b) Atolls: Atolls are … Read more DMPQ- Discuss the following : a) Barrier reef b) Atolls c) Fringing reefs

The Zoological Survey of India (ZSI), with help from Gujarat’s forest department, is attempting for the first time a process to restore coral reefs using biorock or mineral accretion technology. A biorock structure was installed one nautical mile off the Mithapur coast in the Gulf of Kachchh on January 19. Biorock is the name given … Read more DMPQ- Explain Bio rock Technology

Agroforestry is defined as a land use system which integrates trees and shrubs on farmlands and rural landscapes to enhance productivity, profitability, diversity and ecosystem sustainability. It is a dynamic, ecologically based, natural resource management system that, through integration of woody perennials on farms and in the agricultural landscape, diversifies and sustains production and builds … Read more DMPQ- Outline the salient features of the National Agro Forestry Policy, 2014.
