Geography
Geosphere It is the solid part of eath, is divided into three layers.
Mantle It is the layer between the crust and the core. It is the largest layer and contains magma. It is the 84% of Earth.
-
Crust It is the outermost, thinnest layer of the Earth. Its measure it's about 6 to 70km.
Core It is the innermost layer.It is made up of very heavy minerals such as iron and nickel. It's measure is about 2 900km and 3 670km.
The mesosphere, or lower mantle, is made up of magma.

Internal Forces
How do volcanos form? Volcanic mountain formation occurs when two tectonic plates separate, creating a ridge.Magma erupts from the volcano. This lava cools and solidifies, forming mountain ranges and volcanic cones.
.
-
Folding: Folding occurs when two tectonic plates with edges made of relatively soft materials collide
Folding and Subduction: Folding and subduction occur when a thinner oceanic plate and a thicker continental plate collide
Types of relief
-
Continental relief:Continental relief landforms can be divided into four main types: plateaus, plains, valleys, and mountains.

Tectonic plates. The surface of the Earth is in a state of constant motion and evolution due to the planet’s internal forces
*Definition:*The lithosphere is divided into tectonic plates, which are blocks that float on top of the molten materials in the mantle.
Separation:When two plates separate, this creates a fissure
Collision: The formation of a very unstable area known as a fault, which is a break in the Earth’s crust where earthquakes are common.
• Mountain formation, when the edges of the plates fold and rise. If the thinner edge is buried under the thicker one, it causes part of the crust to disappear.
