There are the crust, mantle, and core. The crust is spilt into the oceanic crust and the continental crust. The oceanic crust is thinner, but denser and is the crust below the ocean. Continental Crust is less dense, but thicker and makes up the continents. The mantle is made of hot peridotite rock and is spilt into the lower and upper mantle. The core is split into the inner and outer core. It is made of iron and nickel and is why Earth has a magnetic field. The inner core is a solid, but the outer core is a liquid. The asthenosphere is made of the upper mantle and is solid, but it can flow and bend. The lithosphere is made of the uppermost mantle and the crust, and it is brittle.

As you can see in the picture, magma comes up from the mantle and pushes the current seafloor away. It creates new seafloor. This causes continental drift. Seafloor spreading happens when tectonic plates move apart.

Scientist found more evidence to support his claim such as the distribution of fossils, distribution of rocks and structures, evidence of coral reefs, climate zones, and evidence of glaciers.

You can find the borders of the plates by tracking the epicenters (the place directly above the where there is an earthquake). Seismometers measure ground shaking and are used for recording earthquakes. Earthquakes occur when plates come in contact with each other. They can move away, toward, or slide past each other. Plate boundaries are the place that two plate come together. There are three types of plate boundaries; divergent, convergent, and transform. Lots of geological activity happens at plate boundaries. Plates only move a few centimeters a year. Tectonic plates move because of convection in the mantle. When convection happens, it creates a convection cell in the mantle.

They have a lining of minerals, usually quartz, on the inside. Above that, there is usually a lining of translucent gray and white agate. Geodes can have a rainbow of colors and varieties inside. ]]> 2019-01-31 00:49:51 UTC https://padlet.com/nayasaigal1/padlet_Inside_Earth/wish/326097759 nayasaigal1 https://padlet.com/nayasaigal1/padlet_Inside_Earth/wish/326441088 Fool's gold is also called pyrite and looks almost exactly like gold but is worth nothing compared to real gold. Even though they may look the same, there are many easy tests that you can perform that will let you tell the difference. Pyrite will usually have tarnish on it, but real gold is always bright and shiny. Pyrite has a brass-like color and gold is always golden yellow. There are many other destructive and non-destructive tests that you can perform on fool's gold that lets you tell the difference.
