1、The Structure of the Earth and Plate TectonicsStructure of the Earth The Earth is made up of 3 main layers: Core Mantle CrustInner coreOuter coreMantleCrustThe Crust This is where we live! The Earths crust is made of:Continental Crust- thick (10-70km)- buoyant (less dense than ...
Some of that heat is left over from the planet's formation, but most comes from the radioactive decay of unstable elements. Scientists deduce the Earth's deep internal structure by measuring how seismic waves from earthquakes propagate through it....
Here, tremendous pressure, produced by the weight of the overlying rocks, is strong enough to crowd the atoms tightly together and prevents the liquid state.

Earth Structure - Density Stratified Layers Mantle Chemically the mantle is composed of Fe, Mg, Si and O. (ULTRAMAFIC composed of Fe, Mg silicates) The mantle extends from roughly km below the earth’s surface. Earth Structure - Density Stratified Layers Crust Is composed of two types: Ocean...
Plate Tectonics LEARNING OUTCOMES Explain the concepts of the following hypothesis: continental drift hypothesis, seafloor spreading hypothesis, and the theory of plate tectonics. Describe the three types of tectonic plate and how the processes lead to changes in Earth’s surface features. ESSENTIAL ...
that structure is called anadome. Asynclineis a fold that bends downward, causing the youngest rocks are to be at the center and the oldest are on the outside. When rocks bend downward in a circular structure, that structure is calledabasin. If the rocks are exposed at the surface, wher...
The initiation mechanism of Earth’s plate tectonic cooling system remains uncertain. A growing consensus suggests that multi-plate tectonics was preceded by cooling through a single-plate lithosphere, but models for how this lithosphere was first broken
