Chapter 502: No Natural Disasters from Now on
Of course, the Weapon Star is also a big iron ball, but it is much smaller than Liu Lan Star, with a diameter of only two thousand kilometers.

So because the mass is relatively small, the gravity is naturally relatively small.

Of course, although the gravity is relatively small, it still exists, so it is very necessary to build a spaceport for spacecraft transporting weapons to dock.

What's more, each spacecraft, especially the cargo spacecraft, is considered small if it is a few hundred meters long. Most of them are several thousand meters long, and there are even super large ones that can reach tens of thousands of meters.

However, due to the rigidity of the material itself, this oversized cargo spacecraft can only exist in the microgravity space environment and has no way of landing on the surface of a planet.

Therefore, even though this all-metal planet is small, a spaceport has been built to load and unload weapons and other cargo for cargo ships.

An all-metal planet is enough for the weapon factories on the weapon planet to produce weapons materials for hundreds or even thousands of years.

Of course, because the weapon planet is made of metal, we cannot expect large-scale green forests on it. Of course, humans are not used to living in such an environment, so there are not many people on this weapon planet, and all automated production is automated.

From this point of view, the weapon planet cannot be compared with the wandering blue planet at all, especially the wandering blue planet after the transformation.

Before the transformation, the Wandering Blue Planet had geothermal energy and a magma-like mantle, which resulted in natural disasters such as earthquakes, volcanoes, and lava lakes from time to time. After the transformation, these natural disasters no longer exist.

Of course, lava lakes refer to lake-like geological landscapes formed by high-temperature magma inside the wandering blue planet. They are usually located near volcanic craters and are formed by magma overflowing during volcanic eruptions. In these lava lakes, magma exists in a flowing form. When the magma cools, it forms hard basalt, which is the black or dark gray rock that we often see.

The formation of a lava lake is a rather complicated process. When the temperature of the underground magma reaches hundreds or even thousands of degrees Celsius, it moves upwards due to its low density caused by the high temperature.

Once magma erupts on the surface, if there are not enough cracks or outlets around it, the magma will accumulate in the crater to form a lava pool, thus forming a lava lake. The depth and area of ​​these lava lakes vary, some are only tens of meters deep, while others are hundreds or even thousands of meters wide.

At the surface of the lava lake, you can watch the magma change over time. At first, the magma is hot and flowing, but over time, it cools and solidifies.

This change is caused by the mineral composition of the magma, and when the minerals cool down, they solidify into rocks. These changes are very important for geologists because they can understand the structure and movement of the interior of the wandering blue planet by analyzing these rocks.

Lava lakes are one of the most fascinating and mysterious wonders inside the Wandering Blue Planet. They emit endless heat energy and also bring endless curiosity to humans. By deeply studying the lava lakes, the humans of the Wandering Blue Planet can not only better understand the volcanic activity and magma movement of the Wandering Blue Planet, but also provide geologists with more information and insights about the interior of the Wandering Blue Planet.

Of course, after the Wandering Blue Planet completed the cooling of the earth's core, a super project comparable to building a planetary engine, things like volcanic lava lakes naturally disappeared, because the mantle and the core of the earth were also cooled down and turned into reinforced rocks and iron balls, so these things naturally became invisible.

To cool the core of the earth, we must of course understand the temperature of the core, and this requires first understanding the internal structure of the wandering blue planet.

The interior of the wandering blue planet can be divided into three main parts: the crust, mantle and core. The crust is the surface where humans live, and below the crust is a layer of crust about 2,900 kilometers thick, below the crust is the mantle, and the deepest part is the core.

The core of the earth is divided into two parts, the outer core and the inner core. The outer core is composed of liquid metal, mainly molten iron and nickel, and the temperature of the outer core is about 4,000 degrees Celsius.

This high temperature is caused by the high-energy impact of the rogue blue star during its original formation. During its formation, the rogue blue star experienced a large amount of energy release and high-speed collisions, which led to the increase in the temperature of the earth's core.

Of course, the temperature of the deeper core is naturally much higher, and the core is also composed of iron and nickel. However, due to the huge pressure inside the wandering blue star, although the temperature is as high as six thousand or even tens of thousands of degrees, it is in a solid state.

The high temperature of the Earth's core has an important impact on the operation of wandering blue stars. First of all, the high temperature of the Earth's core is one of the reasons for the formation of the magnetic field of wandering blue stars.

The magnetic field of a wandering blue planet is a key factor in protecting the life on the wandering blue planet from radiation damage from solar wind and cosmic rays.

The high temperature inside the core causes the movement of the outer core, forming the spin magnetic field of the wandering blue star. This magnetic field not only makes the compass point to the North Pole, but also helps the wandering blue star block harmful radiation from space.

The high temperature of the core also affects the structure and plate movement of the Wandering Blue Planet's crust. The Wandering Blue Planet's crust is composed of several continental plates and oceanic plates.

Plate movement is mainly caused by convection in the mantle, and the temperature of the mantle is affected by the heat transfer from the core. The heat from the core is transferred to the mantle, which promotes the convection movement of the mantle, which in turn affects the movement of plates and the formation of the crust.

Plate tectonics refers to the constant movement of the Earth's crust due to tectonic activity inside the Wandering Blue Planet. The Earth's crust is divided into several large pieces called "plates".

The collision, pushing, pulling and sliding of these plates have created geological phenomena such as mountains, volcanoes and trenches on the Wandering Blue Planet. The plates on the Wandering Blue Planet are unevenly distributed, mainly concentrated in the Pacific region, so this area is often called the "plate belt".

Plate movement is one of the important processes in the evolution of wandering blue planets. It not only changes the shape of wandering blue planets, but also affects the climate, environment and organisms on wandering blue planets. For example, earthquakes are caused by plate movement.

When the two plates move relative to each other, huge crustal stress will be generated, which will eventually lead to the rupture of the crust and the release of energy. This will not only bring huge losses to humans, but also have a serious impact on the organisms and ecosystems on the wandering blue planet.

Plate movement can also lead to volcanic eruptions. When two plates collide, one of the plates is squeezed into the mantle and gradually melts to form magma. This magma erupts to the surface through cracks or volcanic vents, forming volcanoes.

Of course, volcanoes not only bring disasters, but volcanic activities also create magnificent landscapes and provide rich nutrients to the surrounding soil, making many areas a treasure trove for agricultural development.

In the process of plate movement, many geological structures are also formed, such as mountains and trenches. Under the action of the mutual push and pull of the two plates, the crust will deform and accumulate into mountains.

For example, the Himalayas are the result of the collision between the hard plate and the Eurasian plate. The trenches in the ocean are formed by the relative sliding of two plates. The formation of these geological structures also provides important clues for scientists to study the history and evolution of wandering blue planets.
