The moving or Sailing stones are found in the Racetrack Playa, which is a dried lake bed, located in the Death Valley National Park of California where the Sailing stones move in a random fashion. Even the heaviest stones which weigh nearly 318 kilograms are moved.The rock trails were as long as 250 meters, while some trails are straight lines and some of them even have sudden bends and curves which baffled the researchers. There are no logical explanations for believing the reason such as wind or dust devils.A NASA scientist named Ralph Lorenz who is already investigating on weather ... Read More

The spiky shrubs such as Cactus are good to look at, but feels hard to maintain as the thought of sharp pain that those thorns can cause will not let most of you say we would love to have one. Desert plants like Cactus, Agave or Mesquite have to survive in deserts where the water is scarce. These desert plants have to fight many odd circumstances to survive.Other plants lose moisture through their pores which they have on their leaves and stem. So, these desert plants need to avoid those pores so as to lock the minimum levels of moisture ... Read More

Just see this.This one too!Scroll down a little...please!!One more!!The last one..!!Hope you got your answer!!Yes! A Mirage can be photographed.Mirage is nothing but an optical illusion that occurs due to the refraction and total internal reflection of light. Mirages could be seen where the land is heated up and the air is cooler, which happens mostly during the summer afternoons. These effects could be found on desert lands, highway roads or open lands.

What could be the needs of a human being to live in an area? The very basic needs like food and water are the essentials. Then comes the convenience of living by making a shelter. But the climatic conditions of a desert area such that these minimum needs are difficult to reach and get populated.Some of the factors which satisfy the fact behind the sparse population in a desert:No water is available and hence people could get dehydrated.the land is not fertile to grow crops, which means no agriculture and no food.The hot desert climate makes you catch heat strokes.Desert ...

We observe that most of the deserts are on the western sides of the continents in the subtropics. These are the results of the prevailing easterly winds of the tropics, which are the trade winds. The trade winds prevail in the lower portion of the earth’s atmosphere, in the lower section of the troposphere.These winds become dry when they reach the western sides of the continents, and hence don’t bring any rain with them. As these regions become devoid of moisture, deserts are formed.Why Like That?The earth rotates on the East side. Moving air is deflected by the Earth’s rotation. ... Read More

Most of the desert plants such as some Cactus, the species of Oenothera like the evening primrose, Cereus etc. bloom at night. A prominent factor is that the flowers of these desert plants get pollinated during night times.The night-flying insects and moths help in the pollination, and thus to increase reproduction. Even these flowers don’t look colorful, as the amount of chlorophyll prepared will be less due to the scarcity of water. Hence they are mostly in white or pale color but these flowers are clever enough to attract the night-flying insects by radiating great smell, for which these insects ... Read More

It is actually sand, which turns the entire phenomenon hot. Sand cannot hold the heat. It acts like a mirror to the sun. During the daytime, it stays warm, and when the Sun is absent it loses all its heat making the nights colder. There’s nothing in the desert that can either absorb heat from the sun or hold it on the surface when the sun is set.Days In DesertThe Sun in the desert can reach the zenith due to which the temperature rises up to 100 degrees Fahrenheit during the day. The sand in the desert gets heated up ... Read More

The Crocodylidae, which includes the "true" crocodiles; the Alligatoridae, which includes the alligator and the caimans; and the Gavialidae, which contains only the gharial are the three groups of crocodilians. Crocodiles are large reptiles which are amphibians. They are found in Asia, Africa, America, and Australia. Alligators are also large reptiles of the family Alligatoridae, members of the order Crocodylia. Alligators are native to the United States and China only. Although these two species look similar, they are different in many ways.There are basically five characteristics with the help of which you can differentiate them from each other. So what ...

A resource is any natural or artificial substance or energy which can be used for the benefits of mankind. Natural resources are those which exist in the environment naturally, that is, they are not created by humans. They are soil, water, sunlight, the wind, plants, coal etc.Natural resources are classified further into exhaustible and inexhaustible resources. Exhaustible resources are those which are limited and will be exhausted with continuous usage, for example, coal, natural gas etc. whereas inexhaustible resources are those which cannot be depleted by human consumption, for example, wind power and water power etc., Need for Conservation of ...

Tsunami means harbor wave in Japanese. These are huge waves of water which are caused by Earthquakes, volcanic eruptions, and other underwater explosions, landslides, meteorite impacts etc. These mentioned activities displace large quantities of water, triggering destructive waves which can measure up to 10 meters tall. They are series of waves with an interval ranging from 5 minutes to few hours.They are very destructive in nature and can wipe out coastal areas, small islands, and ocean basins too. The Indian Ocean tsunami in 2004 was one of the fatal disaster killing approximately 2, 30, 000 people. Tsunamis are not tidal ... Read More
