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?

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
