In short, Yes.
This particle (not molecule) is the atom.
Yes, natural selection causes evolution, which results in the variety of life on earth.
Geology
The boundaries of tectonic plates and the internal structure of the earth.
The mantle is the thickest layer of the Earth.
In short, Yes.
The most common molecule on earth is SiO2.
Ozone molecule harms earth by acting as pollutant. It harms the lungs of living organisms.
Global warming will not threaten the structure of the earth. It will raise sea levels, and it will change croplands into deserts, and vice versa, but the earth's structure will not change.
Astronomy This is the study of the earth and physical structure and history
The Earth has a layered structure consisting of the inner core, outer core, mantle, and crust. The inner core is solid iron, the outer core is liquid iron, the mantle is mostly solid but can flow like a very thick liquid over long timescales, and the crust is the Earth's thin outer shell where we live. This structure is known as the "D-layered Earth model."
The Earth is an oblate spheroid.
The structure of the earth can be described by either the rheological or chemical properties. The structure of the earth is composed of the atmosphere, crust, continent, ocean, hydrosphere, ice cap, mantle, and the asthenosphere.
Geology
What the Earth is made of could be listed as a group of ingredients. How the ingredients are put together is the structure. Big difference.
This particle (not molecule) is the atom.
It is difficult to study the information of the earth and its structure due to a number of reasons. Access to the entire structure of the earth is the main limitation and must studies rely on theories that are no ascertained.
