What is the Earth answer?
[1]Earth is our home planet. Scientists believe Earth and its moon formed around the same time as the rest of the solar system. They think that was about 4.5 billion years ago. Earth is the fifth-largest planet in the solar system.
What is in the Earth?
The Earth’s interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt.

In astronomy, this is 1 AU – or an astronomical unit. Scientists have researched and estimated that our Earth is around 4.5 billion years old.
What is Earth in Brainly?
Earth, our home, is the third planet from the sun. It’s the only planet known to have an atmosphere containing free oxygen, oceans of water on its surface and, of course, life.

Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations. Eratosthenes was born around 276 B.C., which is now Shahhat, Libya.

How was Earth formed?
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
Who called planet Earth?
The answer is, we don’t know. The name “Earth” is derived from both English and German words, ‘eor(th)e/ertha’ and ‘erde’, respectively, which mean ground. But, the handle’s creator is unknown.

Where is our Earth?
Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy. Here we are part of the Solar System – a group of eight planets, as well as numerous comets and asteroids and dwarf planets which orbit the Sun.

Who was the first person on Earth?
Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, adam is also used in the Bible as a pronoun, individually as “a human” and in a collective sense as “mankind”.
When was Adam and Eve born?
They used these variations to create a more reliable molecular clock and found that Adam lived between 120,000 and 156,000 years ago. A comparable analysis of the same men’s mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago1.
How old is the first human?
Scientists have unearthed the jawbone of what they claim is one of the very first humans. The 2.8 million-year-old specimen is 400,000 years older than researchers thought that our kind first emerged.
How did life start on Earth?
It seems possible that the origin of life on the Earth’s surface could have been first prevented by an enormous flux of impacting comets and asteroids, then a much less intense rain of comets may have deposited the very materials that allowed life to form some 3.5 – 3.8 billion years ago.
What was the first thing on Earth?
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.
Where did the earth come from?
Earth formed from debris orbiting around our sun about 4 ½ billion years ago. That is also the approximate age of the sun, but it is not the beginning of our story. The story really begins with the Big Bang nearly 14 billion years ago, which spewed hydrogen atoms throughout the universe.
How did water get on Earth?
Far from the Sun, where temperatures are low, water formed icy objects such as comets, while closer to the Sun water reacted with rocky materials to form hydrated minerals. It’s thought that the mostly likely way that planet Earth inherited its water was from asteroids and comets crashing into it.
Who made water?
Who discovered the water? It was the chemist Henry Cavendish (1731 – 1810), who discovered the composition of water, when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect).
What makes Earth so special?
Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun’s rays.
Does Earth lose water?
Water flows endlessly between the ocean, atmosphere, and land. Earth’s water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.
Can Earth run out oxygen?
Will Earth run out of oxygen? Yes, sadly, the Earth will eventually run out of oxygen — but not for a long time. According to New Scientist, oxygen comprises about 21 percent of Earth’s atmosphere. That robust concentration allows for large and complex organisms to live and thrive on our planet.
How long will the Earth last?
The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.
