Planet earth

 Planet earth 

Soil is the third planet from the Sun after Mercury and Venus, the as it were planet known to be livable, the fifth biggest planet within the sun powered framework and the as it were one within the sun oriented framework with fluid water on its surface, its composition comprises of rocks and minerals.

The plausibility of life on the surface of planet Soil

Soil has an perfect temperature and chemical composition that has made life conceivable on its surface. It is worth noticing that the planet Soil is special in that most of its surface is secured with fluid water, since the temperature permits fluid water to exist for a long time and the vast oceans given a appropriate put for life to start. around 3.8 billion a long time back. 

Size of  earth 

The diameter of planet Earth is 6,371 kilometers, and earth is the fifth largest planet all planetsin solar system. 

Earth distance from the sun is approximately 150 million kilometers, and it takes sunlight about eight minutes to reach on planet Earth.

Earth's route and gyration   

When the Earth revolves around the Sun, it completes one revolution every23.9 hours, taking365.25 days to complete one trip around the Sun. This  redundant quarter of a day challenges the solar  timetable system, which counts one time as 365 days. So to maintain  thickness between the periodic  timetable and the Earth's  trip around the sun, one day is added every four times and the time for which the day is added is called a"  vault time."   The Earth's axis of gyration is  listed by23.4 degrees relative to the aeroplane of the Earth's route around the Sun, and this  cock causes the four seasons to alternate on Earth. During part of the time, the northern semicircle is  listed toward the sun and the southern semicircle is  listed down from the sun. As the sun rises in the sky, solar heating is lesser in the northern semicircle in the summer, while the temperature  position is lower in the southern semicircle in the downtime. Six months  latterly the situation reverses. When spring and fall begin, both components admit  roughly equal  quantities of olfactory heat, and so on.

Structure and formation of the earth

When the solar system was formed by God into the shape of 4 stars 500 million years ago, the earth formed when gravity pulled the gas and dust of the person to become the planet closest to the sun.

Our Earth has a solid crust, a rocky mantle, and a central core like other planets.

There are four basic layers that make up the Earth's core, which consists of a core and a crust.

The inner core is a solid piece of steel and nickel with a diameter of 1,221 km.

The temperature was an average of five thousand four hundred degrees.

The inner core is covered by an outer layer about 2,300 kilometers thick made of liquid iron and nickel.

The most powerful core and crust is the mantle layer, the thickest of which reaches two thousand nine hundred kilometers with a caramel consistency.

The upper layer of our earth's crust is thirty kilometers deep.

The ocean floor crust is thinner as you extend about 5 kilometers from the sea floor to the upper mantle ridge.

The mass of the planet Earth is 5.98×1024 kg, and most of the Earth is made up of:

32.1% Iron

30.1% oxygen

15.1% silicon

13.9% magnesium

2.9% sulphur

1.8% Nickel

1.5% calcium

1.4% aluminum

1.3% contains small amounts of other substances.

since the heavier elements are attracted towards the center while the lighter elements are drawn towards the center it is known as; star separation or star redistribution some people believe that iron is the part of our earth's core it reaches 88.8% with a small amount of nickel

5.8% nickel

4.5% sulphur

1% other elements.

Surface of planet Earth

The surface of planet Earth contains volcanoes, mountains, and valleys, like Mars and Venus. The Earth's lithosphere, which includes the crust (continental and oceanic) and the upper mantle, is divided into huge plates that are constantly moving. For example, the North American plate is moving westward over the Pacific Basin, at roughly the rate our fingernails grow, and earthquakes occur when plates collide with each other, collide to form mountains, or break apart.

The Earth's Global Ocean, which covers nearly seventy percent of the planet's surface, has an average depth of about four kilometers and contains ninety seven percent of Earth's water. Almost all of Earth's volcanoes are hidden beneath these oceans. For example, the Mauna Kea volcano in Hawaii is taller from base to peak than Mount Everest but is mostly underwater. 

The longest mountain extend on Soil is additionally submerged, at the foot of the Ice and Atlantic Seas and is four times taller than the Andes, Rough Mountains and Himalayas combined. 

Earth's atmosphere

Near the planet's surface there is an atmosphere consisting of 78% nitrogen, 21% oxygen, and 1% other gases such as argon, carbon dioxide, and neon. The atmosphere affects the Earth's long-term climate and short-term local weather and provides protection from much of the harmful radiation coming from the Sun. It also provides protection from meteorites, most of which burn up in the atmosphere and are seen as meteorites in the night sky before they can strike the surface as meteoroids.

Earth's magnetosphere

The quick turn of our planet and its liquid center of nickel and press makes a attractive field, which the sun based wind mutilates into a tear shape in space. The sun based wind may be a stream of charged particles always radiated from the Sun. When charged particles from the sun based wind ended up caught in Earth's attractive field, they collide with discuss particles over our planet's attractive shafts. These discuss particles at that point start to shine and cause the aurora, or northern and southern lights. 

The magnetic field is what makes the compass needle point to the North Pole no matter which direction it turns. But the Earth's magnetic polarity can change and fluctuate the direction of the magnetic field. According to the geological record, a magnetic reversal occurs every 400,000 years on average, but this timing is imprecise. According to the information available so far, such a magnetic reversal does not cause any harm to life on Earth, and the reversal is unlikely to occur for at least another thousand years. But when this happens, the compass needles are likely to point in many different directions for a few centuries while the reversal occurs, and after it is complete, the compass will point south instead of north.

the moon

The Earth is the only planet that has one moon, which is a large natural body that revolves around the Earth. The average distance between the Moon and the Earth is about 384,400 kilometers, which is a close enough distance to affect the sea level on the planet Earth, as the moon’s gravity pulls on the planet Earth, but this gravity is too weak to affect the Earth. The entire planet affects the water and makes it move, which is called “tides.”

Soil some of the time briefly has space rocks or expansive rocks that circle it, and they are as a rule held in circle by Earth's gravity for some months or a long time some time recently returning to circle around the sun.
