 Rift valley of Iceland

This image is of a valley in Iceland that is part of the Thingvellir National Park - this valley is not formed by the erosion of a river but by the moving of tectonic plates away from each other - at this point two tectonic plates are separated from each other - on the right is the Eurasian plate which consists of Asia and Europe while on the left The North American plate is composed of the continent of North America - most of the boundary of these plates is at the bottom of the sea so usually not visible - but in Iceland this boundary passes right in the middle of the country

The Eurasian Plate is sliding to the right due to the movement of underground magma while the North American Plate is sliding to the left, which is also expanding the valley and increasing its depth - this type of valley is Rift valley. is done because such valleys are due to the rift of tectonic plates ie moving away from each other are formed. These plates are moving away from each other at the rate of about two centimeters per year. In Thingvellir National Park you can easily walk from one plate to another  

Where tectonic plates are moving towards each other, their collision begins to form mountain ranges and where they are moving away from each other, rift valleys begin to form - in Iceland, since tectonic plates are moving away from each other. Therefore, this valley is forming here - the union and the European plates in the northern regions of the subcontinent They are moving towards the other, so there is a plate sliding over the other, from which the Himalayan mountain ranges are getting higher and higher.

Diabetes: A Hormonal Disease

Diabetes: A Hormonal Disease Diabetes is a hormonal disease. But what are these hormonal disorders? Let's talk about it in detail today.  Various glands in our body continue to make muscle chemicals and add them to the blood stream.These chemicals are called hormones. These hormones play an important role in the body. Such as growing hair on your head, bringing a beard on the face of men, bringing the menstrual cycle of women on time, sexual desire, digesting food and many such tasks. Both a decrease in the production of these hormones or an excess of physiological needs brings negative changes in your body. As the glands in the throat produce a chemical called thyroid, if it is damaged, the heartbeat becomes irregular. constipation persists, Decreased sexual desire. In the same way, our pancreas releases a hormone called insulin. The main function of which is to keep the amount of sugar in the human blood stream at a normal level. When you eat for a long time When y...

Heat Waves

  The Scorching Grip of Summer: Understanding Heat Waves Heat waves, periods of abnormally high temperatures lasting for several days, are a growing concern in a warming world. While seemingly a natural extension of summer, these extreme weather events can pose significant threats to human health, ecosystems, and infrastructure. Let's delve deeper into the science behind heat waves, their far-reaching impacts, and potential solutions to mitigate their effects. Heat waves occur when high-pressure systems trap warm air over a particular region for extended periods. This stagnant air mass compresses and heats up further due to the lack of rising air currents. Additionally, factors like reduced cloud cover allow for more solar radiation to reach the ground, intensifying the heat. The specific criteria for a heat wave vary depending on location and typical climate. However, it generally involves temperatures exceeding average highs for several consecutive days. The consequences of heat ...
