Earth facts for kids



Earth is the third planet from the Sun and is the most special in the solar system. It is about 149,597,890 km from the Sun and is the only planet known to sustain life.

Earth has 70% water, which is only 0.25% of the total mass of the planet. 8% of the Earth has volcanoes, 11% is fertile land used to grow crops, 10% is covered in snow, and a fifth of the Earth's surface is desert land.

The temperature of the Earth's core is about 7,500 Kelvin, which is warmer than the Sun's surface!

The Earth's axis is tilted at an angle of 23 degrees. Due to this, we have four seasons in a year.

A very strong earthquake at sea level causes deadly waves known as tsunamis. Volcanic eruptions within and around the ocean can also cause tsunamis.



Animal facts

Dogs have two distinct airways, one for breathing and the other for the smell. This allows them to store scents in their nose, even when they are exhaling!

Cats do not have collar bones, and their spine is very flexible. When a cat walks, its hind paws step into almost the same location as its front paws were earlier, allowing them to make less noise and leave fewer track marks.

Killer whales, also known as orcas, are not whales at all and are actually a type of dolphin. They are the largest breed of dolphin in existence.

Hummingbirds are the only birds in the world that can fly sideways, backward, up and down, and even in mid-air. They can beat their wings up to 200 times per second. They are famous for being the smallest bird in the world.

Ostriches can run faster than horses and male ostriches roar like lions.



Space facts

In ancient times, the constellations of stars were used to keep track of the calendar and for navigation.

There are more than 125 billion galaxies in our universe. Our galaxy has about 100-400 billion stars.

The collapse of a large dying star creates a black hole. It has a very strong gravitational force that sucks everything including light!

Our solar system is composed of planets, moons, comets, asteroids, miniature planets, dust, and gas. Everything revolves around the Sun.

There are three different types of planets; Terrestrial planets (Mercury, Venus, Earth, and Mars), they have very solid, rocky surfaces, gas giants (Jupiter, Saturn, Uranus, and Neptune), mostly composed of frozen hydrogen and helium, and dwarf planets (Pluto, Ceres, and Eris), small circular planets orbiting the Sun.



Technology facts

Televisions receive and then display a broadcast of images that move so fast, they appear to the human eye as smooth motion.

The Internet and the World Wide Web are not the same things. The Internet is a network of other small networks that connect computers together all over the world. The World Wide Web is a collection of linked pages that can be accessed with the help of the Internet and a web browser.

All electrical devices have fuses. Fuses are essentially fire breakers. If there is a power surge, the fuse will break, preventing any damage or fire.

Electronic computers were developed around the 1940s and were the size of a large room. Today, computers have become so small that they have been embedded in other things such as microwaves, toys, cell phones, etc.

In 1495, Leonardo da Vinci abandoned designs for a humanoid robot. Today, many robot prototypes are being built. also, more read prsideas

1. Babies have about 100 more bones than adults

Babies have about 300 bones at birth, many of which have cartilage between them. This extra flexibility helps them pass through the birth canal and also allows for faster growth. With age, many of the bones fuse, leaving 206 bones that make up an average adult skeleton.

2. Eiffel Tower can be 15 cm tall during summer

When a substance is heated, its particles increase further and form larger amounts - this is known as thermal expansion. Conversely, a drop in temperature causes it to shrink again. For example, the mercury level inside the thermometer increases, and the number of mercury changes with the ambient temperature. This effect is most dramatic in gases, but also in liquids and solids such as iron. For this reason, large structures such as bridges are built with expansion joints that allow them to expand and contract without causing any damage.


3. 20% of the Earth's oxygen is produced by the Amazon rainforest

Our atmosphere is made up of about 78 percent nitrogen and 21 percent oxygen, with some other gases present in small quantities. Most organisms living on Earth require oxygen to survive, converting it to carbon dioxide as they breathe. Thankfully, plants continuously replenish our planet's oxygen levels through photosynthesis. During this process, carbon dioxide and water are converted into energy, releasing oxygen as a by-product. Covering 5.5 million square kilometers (2.1 million square miles), the Amazon rainforest cycles a significant proportion of the Earth's oxygen, absorbing large amounts of carbon dioxide at the same time.


4. Some metals are so reactive that they come into contact with water

There are some metals - including potassium, sodium, lithium, rubidium, and cesium - that are so reactive that they oxidize (or tarnish) immediately upon exposure to air. They can also explode when dropped in water! All elements try to be chemically stable - in other words, to be a complete external electron shell. To achieve this, metals flow electrons. Alkali metals have only one electron on their outer covering, which makes them ultra-keen to make this unwanted passenger bond to another element. As a result, they form compounds with other elements so easily that they do not exist independently in nature.


5. One teaspoon of a neutron star will weigh 6 billion tons

A neutron star is the remnant of a massive star that has run out of fuel. The dying star explodes into a supernova, while its core collapses on its own due to gravity, forming a super-dense neutron star. Equivalent to the mass of the Sun (ie 2 x 1030 kg / 4.4 x 1030 lb) In solar astrophysicists, astronomers measure the mass of stars or galaxies in solar masses. Typical neutron stars have masses of up to three solar masses, spherical with a radius of about ten kilometers (6.2 mi) - resulting in some of the densest matter in the known universe.


6. Hawaii moves about 7.5 cm to Alaska every year

The earth's crust is divided into huge pieces called tectonic plates. These plates are in constant motion, driven by currents in the Earth's upper mantle. Warmer, less-dense rocks erupt before cooling and sinking, giving rise to circular convection currents, which act like huge conveyor belts, gradually moving tectonic plates over them. Hawaii sits in the middle of the Pacific Plate, which is slowly flowing northwest toward the North American Plate, back toward Alaska. The speed of the plates is equal to the speed at which our nails grow.


7. Chalk is made from fossils of micro-billion plankton

Small single-celled algae, called coccolithophores, have lived in the Earth's oceans for 200 million years. Unlike any other marine plant, they surround themselves with minuscule plates of calcite (coccoliths). 100 million years ago, conditions were fine for Coccolithophorus to accumulate in the seabed with a thick layer coating a white layer. As further sediment was formed above, the pressure compressed the coccolith to form rock, depositing the white rocks of Dover such as chalk. Coccolithophores are just one of many prehistoric species that have become immortalized in fossil form, but how do we know how old they are? Over time, the rocks form in horizontal layers, with older rocks at the bottom and younger rocks near the top. By studying the type of rock in which fossils are found, paleontologists can estimate its age. Carbon dating estimates that the age of fossils is more accurate, based on the rate of decay of radioactive elements such as carbon-14.amazing facts in Hindi about nature

    importance of education in our life And Education Importance

     The importance of education in our life can be considered as the transmission of values ​​and accumulated knowledge of society. In this sense, it is equivalent to socialization or humiliation of social scientists. Children - whether they were born among the Aborigines of New Guinea, the Renaissance Florentine, or the middle class of Manhattan, are born without culture. Education is designed to guide them towards learning a culture, adapting their behavior to the ways of adulthood, and their ultimate role in society. In most primitive cultures, there are often very few learners formally - who usually call schools or classrooms or teachers. Instead, the entire environment and all activities are often seen as schools and classrooms, and many or all adults act as teachers. As societies become more complex, however, the amount of knowledge that can be passed from one generation to another may be greater than any one individual, and therefore, more selective and efficient means of cultural transmission must be developed. The result is formal education - the school and the specialist are called teachers.

    Best Importance Of Education In Our Life 

    As society becomes ever more complex and schools become ever more institutionalized, educational experiences become directly related to daily life, there is less case to show and learn in the context of the functional world, and more abstracted from practice, More disturbing case. Learning and learning out of context. This concentration of learning in a formal environment allows children to learn much more than their culture, as they are only able to observe and imitate. As society gradually attaches more and more importance to education, it also attempts to formulate the overall objectives, content, organization, and strategies of education. Literature gets laden with the advice of the upbringing of the younger generation. In short, the philosophy and principles of education development.



    Prehistoric and Primitive Cultures

    The term education can only be applied to primitive cultures in the sense of insult, which is a process of cultural transmission. A primitive person, whose culture is the totality of his universe, has a relatively definite sense of cultural continuity and timelessness. The model of life is relatively stable and absolute, and it propagates from one generation to another with little deviation. For prehistoric education, this can only be inferred from educational practices in living primitive cultures.


    Thus the aim of primitive education is to guide children to become good members of their tribe or band. There is a clear emphasis on training for citizenship, as primitive people are highly concerned with the development of individuals as tribal members and have an in-depth understanding of their way of life from pre-puberty to post-puberty.


    Because of the diversity in the countless thousands of primitive cultures, it is difficult to describe any of the standards and similar characteristics of pre-education. Nevertheless, some things are commonly practiced within cultures. Children actually participate in the social processes of adult activities, and their participation is based on learning that American anthropologist Margaret Mead called empathy, identity, and copulation. Primitive children learn by doing and observing basic technical practices before reaching puberty. His teachers are not strangers, but his immediate community.
