Understanding Endogenic Processes

What are endogenic processes?

• Processes that occur on the Earth's surface

• Weathering caused by external forces

• Volcanic eruptions caused by surface activity

• Endogenic processes are geological processes originating from within the Earth.

Which of the following is a source of internal heat?

• Geothermal energy

• Solar energy

• Wind energy

• Nuclear energy

What is primordial heat?

• Heat generated by nuclear fusion in stars.

• Residual thermal energy from the formation of celestial bodies.

• Thermal energy from volcanic activity on Earth.

• Energy produced by chemical reactions in living organisms.

Which element is NOT a source of radiogenic heat?

• Silicon

• Oxygen

• Hydrogen

• Carbon

What is the primary method of heat transfer in solids?

• Conduction

• Radiation

• Evaporation

• Convection

In which state of matter does convection primarily occur?

• Only in solids

• Solid and plasma

• Liquid and gas

• Only in gases

What is the process of heat exchange between the Sun and the Earth called?

• Absorption

• Radiation

• Convection

• Conduction

Which of the following processes contributes to the formation of volcanoes?

• Weathering of volcanic ash

• Formation of sedimentary rocks

• Erosion of mountains

• Magma rising from the mantle to the surface.

What role does thermal energy play in mountain formation?

• Thermal energy only affects ocean currents, not land formations.

• Thermal energy drives tectonic activity that leads to mountain formation.

• Thermal energy has no impact on geological processes.

• Thermal energy cools the Earth's crust, preventing mountain formation.

Which radioactive elements are primarily responsible for radiogenic heat?

• Radon-222

• Uranium-238, Uranium-235, Thorium-232, Potassium-40

• Carbon-14

• Bismuth-210
