WORLD WATER DAY Water is a source of life. For example, water is needed in all functions that take place in the human body (such as digestion, circulation, breathing, emptying, reproduction). Therefore, the presence of liquid water is being investigated in the search for life outside the Earth. From space, our planet appears as a blue sphere. That's because about 71% of its surface is covered with water. Liquid water is the most important substance that separates the Earth from other planets in the solar system. Geological evidence suggests that liquid water has existed on Earth for 3.8 billion years . Usually there are large differences between the melting and boiling temperatures of a substance. However, water can be found in solid, liquid and gaseering at a relatively narrow temperature range. And is the water the source of life as much as we think on our planet? There's water on Earth, equal to the volum...
OUR FORESTS Have you ever wondered how the world breathes? It is not wrong to answer this question as "Thanks to the forests". Forests are one of the most important sources of oxygen in the world. The forest is a natural land ecosystem consisting of various trees of a certain height and size, shrubs, herbaceous plants, fungi, microorganisms and animals. Lush forests, which have many benefits for the earth, house a large number of trees. Considering the number of leaves in each tree, it can be understood why trees are a very large source of oxygen. On earth, 31% of the land is covered with forests. 47% of the forests are tropical belt rainforests, 9% are temperate belt tropical rainforests, 11% are temperate belt broad-leaved forests and 33% are coniferous forests, also known as taiga. Forests that are a source of oxygen for our world also have a regulatory effect on the climate. Not only do they clean the air of the area where they are located, but they also ensure ...
E-GÜVENLİK Dijital çağda çocuk yetiştirmek, özellikle iPad, akıllı telefon veya dizüstü bilgisayar olmadan büyüyen ebeveynler ve bakıcılar için zor olabilir. Sonuçta, bu yetişkinler nispeten yeni bir olguyla uğraşıyorlar ve eski nesillerin deneyimlerine veya tavsiyelerine kolayca güvenemezler. Birçoğunun ülke çapındaki kilitlenme (Pandemi) sırasında çevrimiçi okul kaynaklarına güvendiği göz önüne alındığında, çocuklar arasında internete bağlı cihazların bulunabilirliği ve kullanımı sürekli olarak artmaktadır. Düzenleyiciler, kanun koyucular ve ebeveynler nihayet çocukların çevrimiçi ortamda ne yaptığını anladıklarını varsaysalar da, sürekli değişen teknoloji, gençlerin her gün yeni internet tehlikelerine maruz kalması anlamına geliyor. ...
