Solid metal
No. They just look like they are.
1. earth is not dicovered by any one 2. earth is not named after any one
it is a nice question . the answer should be Crust.
you are on earth
You can't go inside Earth due to its thick crust, mantle, and core, which are made of solid and molten rock. Other planets like Mars or Venus do not have the same layered structure as Earth, making it physically impossible to penetrate their surfaces and go inside like on Earth.
The mantle convection currents push and move tectonic plates from inside the Earth. This movement helps drive plate tectonics and shape the Earth's surface through processes like subduction and seafloor spreading.
It is difficult to know what is inside the Earth because it is not directly accessible to us. Most of our information comes from indirect methods like seismic waves and drilling, which only provide limited insights into the Earth's interior. The extreme heat and pressure also make it challenging to study materials deep within the Earth.
There are actually many layers inside the earth, much like an onion. The very center of the earth however, is called the core.
The Earth's crust is like a cover that surrounds the mantle and core. The crust is composed of solid rock and is relatively thin compared to the other layers of the Earth.
earth
We know about the inside of the Earth through seismic waves, which are waves generated by earthquakes. These waves travel through the Earth and can be detected and measured by seismographs on the surface. By analyzing how these waves behave and interact with different materials inside the Earth, scientists can infer the composition and structure of the Earth's interior.
The various layers inside the earth range from solid rock, like the crust, to liquid metals, like the earth's outer core.
