"The internal structure of Earth is the solid portion of the Earth, excluding its atmosphere and hydrosphere."
An overview of Earth's interior structure, including the core, mantle, and crust, and how these layers interact to shape the surface of the planet.
Structure of the Earth: This involves understanding the composition, layers, and density of the Earth's interior, including the crust, mantle, and core.
Plate Tectonics: This is the study of how the Earth's crust is divided into plates that move and interact with each other, leading to phenomena such as earthquakes and volcanic eruptions.
Seismology: This is the study of earthquakes and seismic waves, which can provide insight into the structure and properties of the Earth's interior.
Earthquakes: The study of how and why they occur, including the causes and effects that can result from them.
Volcanology: The study of volcanoes and how they form, erupt, and impact both the Earth's surface and its atmosphere.
Mineralogy: The study of minerals and their properties, which can help us understand the composition of the Earth's interior.
Petrology: The study of rocks and their formation, which can provide information about the Earth's past and the processes that have shaped its interior.
Geophysics: The study of the physical properties of the Earth's interior, including gravity, magnetism, and geothermal energy.
Geology: The study of the Earth's history and the processes that have shaped its surface and interior over time.
Geochemistry: The study of the chemical composition of the Earth and its processes, including the formation and evolution of the Earth's crust, so as to give insights on the interior composition.
Water Cycle: This refers to the cycle of water between the Earth's surface and the atmosphere, and includes processes such as evaporation, precipitation, and transpiration.
Climate Change: The study of how the Earth's climate is changing over time and the impacts that this will have on the planet's surface and interior.
Geologic Time Scale: The study of the timeline of Earth's history, including significant events and time periods that shaped the planet's surface and interior.
Geothermal Energy: The study of using the Earth's internal heat sources for energy production, which can help in providing renewable resources.
Crust: This is the outermost layer of the Earth, ranging from 5 to 70 km in thickness. It is made up of solid rocks, and it is one of the thinnest layers of the Earth.
Mantle: The mantle is the largest layer of the Earth and is located between the crust and the core. It is divided into the upper mantle and the lower mantle. The upper mantle is solid, and the lower mantle is in a state of plasticity. It is composed of various types of rocks and minerals.
Outer Core: This is a liquid layer of the Earth, located between the mantle and the inner core. It is the only liquid layer of the Earth, and it consists mostly of molten iron and nickel.
Inner Core: This is the innermost layer of the Earth, and it is also the hottest and most dense layer. It is a solid sphere made up of iron and nickel, and its temperature is estimated to be around 5,500 degrees Celsius.
"The structure consists of an outer silicate solid crust, a highly viscous asthenosphere and solid mantle, a liquid outer core whose flow generates the Earth's magnetic field, and a solid inner core."
"Scientific understanding of the internal structure of Earth is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanoes or volcanic activity, analysis of the seismic waves that pass through Earth, measurements of the gravitational and magnetic fields of Earth, and experiments with crystalline solids at pressures and temperatures characteristic of Earth's deep interior."
