What are the two internal processes that create landforms?
Constructive forces include plate tectonics and deposition.

Heat convection inside Earth drives volcanoes and earthquakes that formed the oceans and the continents. Igneous rocks form when lava cools down. Plate tectonics and volcanoes form mountains. Weathering breaks down rocks into smaller components like pebbles and dirt.
The forces that act on the surface of the earth due to natural agents like running water, glacier, wind, waves, etc., are called External processes or Exogenetic processes. These external processes tear the landscape down into relatively low elevated plains and shapes the landform created by Endogenetic process.
Plate motion is caused by a combination of forces. Thermal energy from Earth’s interior drives plate motion in a process called convection. As plates move and interact along plate boundaries, forces like slab pull, ridge push, and friction also contribute to the process.
The internal processes are referred to as diastrophism and they tend to elevate the earth’s surface. They are counterbalanced by the external processes that wear down the land surface. The constant interaction between these two processes determines the configuration of the earth’s surface.
Internal processes occur due to the internal heat of the Earth’s interior. The movement in the lithospheric plate is the biggest example of internal processes. Volcanoes, earthquakes are all example of internal process caused by the disturbance in the earth’s layer.
