Planet Earth

We made an application that explains the elements that make up the planet and what is the importance of life and preserving this planet

At first, we described the planet Earth as the third planet in the solar system, as there is no life within this group except on planet Earth

The Earth revolves around its axis, making up the day and night in 24 hours, and it revolves around the sun with a period of 365 days.

We described the land as consisting of water bodies, which reach 71% and the land area is 29%

There are also the inner layers, where they fall starting from the core and a huge strong ball with a diameter of about 2450 km, then comes the outer core, which consists of iron and nickel, but takes the liquid state in it.

Its thickness is about a thousand kilometers, which causes the movements of the earth's surface, and finally comes the earth's crust, and its thickness is about 30 km.

We also describe the layers of the atmosphere, which mainly consists of five layers

1 troposphere

2 mesosphere

3 thermosphere

4 inosphere

5 Exosphere

Since the troposphere is the layer in which we live, we have put together an illustrative video of the layers of the atmosphere that make up the planet Earth, where it describes each layer more clearly.

We also described in a video illustrative how the four seasons alternate throughout the year and how the four seasons occur on the planet during 365 consecutive days of winter, and how a large part of the sun’s rays are scattered and the winter season follows, followed by spring, summer and finally autumn.

There is the importance of the atmosphere, which gives only the appropriate warmth and heat to the planet and reflects harmful rays.

We talked about factors that help to live on planet Earth, where the most important of these factors were the magnetic field and the atmosphere that we talked about at the beginning and finally the mineral resources that provide sources of life for humans.

We put a video explaining the work of tectonic plates and a short description of these plates, in addition to the water bodies that reside on the ground and cover 71% of the total area.

It is nice to have a small test that reviews the information you have read inside the application, and we hope that you like it.
