Life as we know it reparto

the importance of water

Life as we know it today is not designed for having children. All of us who are parents throw our hands over our heads every summer trying to figure out how we are going to organize it, so that we can be with and enjoy our children and at the same time fulfill our work obligations that allow us to live.

Many others turn to the invaluable help of grandparents and the less fortunate have to resort to summer camps and endless sports days, which allow us to have caregivers during the time of the working day.

Before getting into a panic situation, you should read your divorce or guardianship and custody agreement to be clear about how the vacation period is divided up.

The calendar that indicates the exact period is the one of the school center to which the minor children attend or, in case it does not exist, the school calendar of the locality or autonomous community in which the school center is located.

where fresh water is found

The geosphere is the solid layer of the Earth made up of minerals, rock formations and the ground we walk on, as well as other inner layers of the Earth that we do not see, which even have rock in a liquid state because of their high temperatures. The geosphere provides sustenance for most of the life on our planet.

The geosphere is fundamental to life on the planet. In a large number of places on Earth, the geosphere has a layer of soil that provides living organisms with the nutrients necessary for their survival, and thus provides an ecological habitat that is the basis for different forms of life on our planet.

The crust is the most superficial layer of the Geosphere, it is also the thinnest, most rudimentary and coldest of all the Earth’s inner layers. All known life in the universe has had the crust as its home. Its structure is dynamic due to plate tectonics, and three types of rocks are found in it: igneous, sedimentary, magmatic and metamorphic.

percentage of fresh water on earth

Oxygen is the third most abundant element in the universe, after hydrogen and helium. It is generated mainly in the interior of the largest stars, and is incorporated into the interstellar medium when they finally explode as supernovae. Thus, through the formation and evolution of successive generations of massive stars, primordial hydrogen and helium are transformed into oxygen and other heavy elements.

However, their biologically relevant form, the diatomic form (O2), is extremely rare in the universe, especially if we compare it with diatomic hydrogen (H2): for each molecule of O2 there are millions of H2. This difference is due to the fact that the binding energy of oxygen is very high and therefore, isolated oxygen atoms in the universe will bind to stardust particles before each other. The few cases where higher concentrations of molecular or diatomic oxygen have been detected, such as in the Orion Nebula, are probably due to shock waves that have temporarily separated the oxygen from the stardust.

salt water and fresh water

When we think of the amount of water on the planet, we may have a sense of abundance. But how much fresh water is there really on Earth? If we look at the numbers, the feeling of abundance is replaced by one of concern about scarcity. Find out how much drinking water there is on the planet and why we must protect this precious commodity.

Water is essential for the survival of the planet. Without it, life and biodiversity as we know it would disappear. Human activity requires vast quantities of water for most of our daily activities. However, this precious commodity is highly scarce and, with each passing day, we are progressively approaching the dreaded water shortage. In this article we answer the question of how much drinking water is available on earth and explain its proportion compared to other types.

This makes us aware that water is a scarce and limited resource as well as a right in an unequal world. Lack of access to it is a cause of poverty, inequality, social injustice and creates great differences in the opportunities offered by life.
