Answer:

Explanation:
An understanding of the structure of the Earth is important for many reasons
1. It can help us understand things that happen on the surface, like the magnetic field. The structure of the Earth explains that.
2. Things like tectonic plates severely affect the planet, such as the creation of many natural disasters. Understanding them helps us better prepare and anticipate them.
3. Understanding the structure of the Earth can help us identify the location of important natural resources (like different metals)
4. In the production of things like geothermal energy we need to understand the Earth's structure to know where we will get the most heat
4.6 billion years ago - most likely hydrogen (H2) and helium (He)
probably rich in hydrogen compounds like methane (CH4), ammonia (NH3), hydrogen cyanide (HCN), water (H2O), and formaldehyde (HCHO). Also some N2, CO2 but LITTLE or NO free oxygen.
Molecules of H2 and He move really fast, especially when warm, that they eventually all escaped Earth's gravity and drifted off into space.
C. Law of superposition because it is the principle that the oldest layer of sediment will be found on the bottom
