Our Home – Planet Earth

The third planet from the sun, Earth is our house. The Earth is the fifth largest planet in the solar system, the largest inner planet. It is the only planet known to have life. From space, you can see the amount of water on our planet.

Our planet consists of various layers. The layer in which we live is called the Earth's crust. This thin layer consists of many different plates that move along the Earth's crust. There is a mantle under the crust. This layer is made of rock. The center of the earth is the core. The core consists of two layers, the outer core and the kernel. The outer core is a liquid layer and the inner core is a boiling hot solid layer.

About 6 billion years ago, our hometown, the Earth, was formed in disarray. The first 600 million years of our house was destroyed, violently bombarded, the temperature rose and a life-threatening gas mixture occurred. As the complexity of the chemicals increases, the first lighthouse of life shines about 4 billion years ago; life is made of carbon. The first primitive human appearance took nearly 4 billion years. 4 billion years. The modern human being, Homo sapiens evolved only about 200,000 years ago. It's a very meaningless period of life on this planet. In the past 200 years, we have begun to see the possibility of human beings that are both destructive and constructive.

This is the time when we talked about our mother planet, the earth, its understanding in the context that it becomes a planet, and how our planet exploration will give us information and stimulate to explore It is the earth! (Look at the first part - Episode 031 - About the planet: Why explore and why we know) This week we will enter space, but do not depart so much. Our quest starts with the definition of our planet's house - solar system. What is it, where it comes from, and how far is it actually going? From there we sneak into the center and talk about the sun, the mother of all the planets. Even if we enter the internal solar system (aka Rock Planet, Mercury, Venus, Earth, Mars), our exploration will continue out. We will talk about the exploration we have done so far, what we know, and why it is very exciting. We stopped even on the moon on the earth.

What is the physical characteristic of the earth? Our home planet is only one of the celestial bodies circling the sun. It has many features in common with other planets and satellites in the solar system. But it is unique in a special sense - there is life on earth. Life was not found anywhere else in the universe. However, given the number of stars and planets in the universe, scientists think that it is possible. Many physical features on the planet make it an ideal place for life development
