Mercury's density and size can be used to infer details of its inner structure. While the Earth's high density results appreciably from gravitational compression, particularly at the core, Mercury is much smaller and its inner regions are not nearly as strongly compressed. Therefore, for it to have such a high density, its core must be large and rich in iron. Geologists estimate that Mercury's core occupies about 42% of its volume; for Earth this proportion is 17%. Recent research strongly suggests Mercury has a molten core.
Surrounding the core is a 600 km mantle. It is generally thought that early in Mercury's history, a giant impact with a body several hundred kilometers across stripped the planet of much of its original mantle material, resulting in the relatively thin mantle compared to the sizable core.
Based on data from the Mariner 10 mission and Earth-based observation, Mercury's crust is believed to be 100-300 km thick. One distinctive feature of Mercury's surface are numerous narrow ridges, some extending over several hundred kilometers. It is believed that these were formed as Mercury's core and mantle cooled and contracted at a time when the crust had already solidified.

What is a internal composition?
Internal composition refers to the structure or makeup of something from within. It describes the arrangement of components or elements that form a particular object, entity, or system. Understanding the internal composition of a structure is essential for analyzing its properties and behavior.
Why are saphires and rubies different colors?
because of different internal chemical composition .
Is internal equilibrium from quasi equilibrium?
No, internal equilibrium is not the same as quasi equilibrium. Internal equilibrium refers to a system being in a state where there is no net change in composition, while quasi equilibrium refers to a process that occurs almost at equilibrium, but not necessarily at the exact equilibrium point.
What is called the study of internal parts of plant and animal?
The study of internal parts of plants and animals is called anatomy. Anatomy focuses on the structure, composition, and organization of living organisms at a microscopic and macroscopic level. It plays a crucial role in understanding the functioning and relationships of internal organs and tissues within organisms.
Does internal energy of system depends upon volume?
Internal energy is an extensive state function. That means it depends on how much of a substance you have but if you fix the composition, pressure, temperature, volume, and (in the case of a system at a phase equlibrium point, like water at the freezing point) the phase of a system, the specific internal energy will be constant. If you take a closed system and change the volume of it, you will be doing work (or allowing the system to do work) and the internal energy can change - so - yes - internal energy of a system depends upon volume. Also, if you fix the composition, temperature, pressure, and phase of a homogeneous mass but change the volume, you will increase the amount of mass you included in the system, thus changing the total internal energy (because it is, after all, an extensive function).
What is mercury's internal composition?
Mercury's internal composition is made up of 70 percent metals and 30 percent silicate. The core is a hot, liquid iron-nickel mixture.

The exact internal composition of Pluto is still unknown, but it is described as being both rocky and icy.
Why are saphires and rubies different colors?

What is the internal composition of the planet Jupiter?
1063 s6 surface area x is it for a test????x
What two factors control the properties of a mineral?
The chemical composition and the internal structure of a mineral control its properties. The specific arrangement of atoms and the types of chemical bonds present determine characteristics such as hardness, color, and cleavage.
What is mercury internal?
Mercury's internal composition is made up of 70 percent metals and 30 percent silicate. The core is a hot, liquid iron-nickel mixture.
