Plate Tectonics

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath the other, leading to subduction, mountain building, or volcanic activity.

The outer core is a layer of the Earth composed of liquid iron and nickel, located beneath the mantle and above the inner core, responsible for generating the Earth's magnetic field.

Earth's tectonic plates move due to convection currents in the mantle, which are caused by the heat from the Earth's core.

At a divergent boundary, tectonic plates move apart from each other, leading to phenomena such as sea floor spreading and the formation of rift valleys.

A divergent plate boundary is where two tectonic plates move away from each other, often resulting in the creation of new oceanic crust.

Sea floor spreading is the process by which new oceanic crust is formed at divergent boundaries as magma rises from the mantle and solidifies.

A transform plate boundary is where two tectonic plates slide past each other horizontally, often causing earthquakes.

Subduction is the process where one tectonic plate is forced under another, often leading to volcanic activity and the formation of deep ocean trenches.

The mantle is the thick layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

The crust is the outermost layer of the Earth, consisting of solid rock and soil, where we live.
