Endogenic Processes
Endogenic processes are processes that occur within the Earth’s crust. They are responsible for the formation of mountains, VolcanoesVolcanoes, and earthquakes.
The following are some of the subtopics of endogenic processes:
- Convection currents
- Subduction
- Orogeny
- Volcanism:
- Earthquakes
- Plate tectonics: The theory that the Earth’s surface is made up of a number of plates that move around on the mantle.
- Convection currents: The movement of heat in the Earth’s mantle that causes the plates to move.
- Subduction: The process by which one plate of the Earth’s crust is forced under another plate.
- Orogeny: The process of mountain building.
- Volcanism: The process of magma erupting from the Earth’s surface.
- Earthquakes: The shaking of the Earth’s surface caused by the movement of tectonic plates.
Endogenic processes are processes that occur within the Earth’s crust. They are responsible for the formation of mountains, Volcanoes, and earthquakes.
Plate tectonics is the theory that the Earth’s surface is made up of a number of plates that move around on the mantle. The plates are made up of the Earth’s crust and the uppermost part of the mantle. The plates are constantly moving, and they can collide, grind past each other, or spread apart.
Convection currents are the movement of heat in the Earth’s mantle that causes the plates to move. The mantle is made up of hot, molten rock. The heat from the Earth’s core causes the rock to rise to the surface. As the rock rises, it cools and sinks back down to the core. This movement of the rock creates convection currents.
Subduction is the process by which one plate of the Earth’s crust is forced under another plate. This happens when two plates collide. The denser plate is forced under the less dense plate. The process of subduction can cause earthquakes and volcanoes.
Orogeny is the process of mountain building. Mountains are formed when two plates collide. The collision causes the plates to fold and buckle. The folded and buckled rock is what forms mountains.
Volcanism is the process of magma erupting from the Earth’s surface. Magma is molten rock that is found beneath the Earth’s surface. When magma erupts from a volcano, it is called lava. Lava can flow down the sides of a volcano and cool to form rocks.
Earthquakes are the shaking of the Earth’s surface caused by the movement of tectonic plates. Earthquakes can cause damage to buildings and InfrastructureInfrastructure. They can also cause landslides and tsunamis.
Endogenic processes are a vital part of the Earth’s system. They are responsible for the formation of some of the most important features on Earth, such as mountains, volcanoes, and earthquakes. These processes also play a role in the Earth’s climate and weather.
Endogenic processes are constantly happening, and they are constantly changing the Earth’s surface. The next time you see a mountain, a volcano, or an earthquake, remember that it is the result of endogenic processes.

What are endogenic processes?
Endogenic processes are processes that occur within the Earth’s crust. They are responsible for the formation of mountains, volcanoes, and earthquakes.
What are some of the subtopics of endogenic processes?
Some of the subtopics of endogenic processes include:
- Plate tectonics: The theory that the Earth’s surface is made up of a number of plates that move around on the mantle.
- Convection currents: The movement of heat in the Earth’s mantle that causes the plates to move.

What is plate tectonics?
Plate tectonics is the theory that the Earth’s surface is made up of a number of plates that move around on the mantle. The plates are made up of the Earth’s crust and the uppermost part of the mantle. The plates are constantly moving, and they can collide, grind past each other, or spread apart.
What are convection currents?
Convection currents are the movement of heat in the Earth’s mantle. The heat causes the mantle to move in a circular motion, like a pot of boiling water. The movement of the mantle causes the plates to move.
What is subduction?
Subduction is the process by which one plate of the Earth’s crust is forced under another plate. The plate that is forced under is called the subducting plate, and the plate that is on top is called the overriding plate. The subduction process is what causes earthquakes and volcanoes.
What is orogeny?
Orogeny is the process of mountain building. Mountains are formed when two plates collide and the crust is pushed up. The higher the mountains, the more the plates have collided.
What is volcanism?
Volcanism is the process of magma erupting from the Earth’s surface. Magma is molten rock that is found beneath the Earth’s surface. When magma erupts, it can form volcanoes, lava flows, and ash clouds.
What are earthquakes?
Earthquakes are the shaking of the Earth’s surface caused by the movement of tectonic plates. The movement of the plates can cause the Earth’s crust to break, and this can release energy in the form of seismic waves. The seismic waves can cause the Earth’s surface to shake.
What are the effects of endogenic processes?
The effects of endogenic processes can be both positive and negative. Positive effects include the formation of mountains, which provide resources such as minerals and water. Negative effects include earthquakes and volcanoes, which can cause damage to property and loss of life.
MCQS
Which of the following is not an endogenic process?
(A) Plate tectonics
(B) Convection currents
(CC) Subduction
(D) Orogeny
(E) Weathering
Answer
(E) Weathering is an exogenic process, not an endogenic process. Weathering is the process by which rocks and minerals are broken down by the action of the AtmosphereAtmosphere, water, and ice.
Question 2
Which of the following is the most important factor in causing earthquakes?
(A) Plate tectonics
(B) Convection currents
(C) Subduction
(D) Orogeny
(E) Volcanism
Answer
(A) Plate tectonics is the most important factor in causing earthquakes. Earthquakes are caused by the movement of tectonic plates. When two plates move past each other, they can grind together or one plate can be forced under the other. This movement can cause the Earth’s crust to break, releasing energy in the form of seismic waves.
Question 3
What is the process by which mountains are formed?
(A) Plate tectonics
(B) Convection currents
(C) Subduction
(D) Orogeny
(E) Volcanism
Answer
(D) Orogeny is the process by which mountains are formed. Orogeny is a long-term process that is caused by the collision of tectonic plates. When two plates collide, they can grind together or one plate can be forced under the other. This movement can cause the Earth’s crust to fold and buckle, forming mountains.
Question 4
What is the process by which magma erupts from the Earth’s surface?
(A) Plate tectonics
(B) Convection currents
(C) Subduction
(D) Orogeny
(E) Volcanism
Answer
(E) Volcanism is the process by which magma erupts from the Earth’s surface. Volcanism is caused by the movement of magma in the Earth’s mantle. Magma is molten rock that rises to the surface through cracks in the Earth’s crust. When magma reaches the surface, it can erupt in the form of lava, ash, and gas.
Question 5
What is the shaking of the Earth’s surface caused by the movement of tectonic plates?
(A) Plate tectonics
(B) Convection currents
(C) Subduction
(D) Orogeny
(E) Earthquakes
Answer
(E) Earthquakes are the shaking of the Earth’s surface caused by the movement of tectonic plates. Earthquakes are caused by the sudden release of energy when tectonic plates move past each other. This energy can travel through the Earth’s crust in the form of seismic waves. When these waves reach the Earth’s surface, they can cause the ground to shake.
