Who proposed the continental drift theory?

• Charles Darwin

• Alfred Wegener

• Isaac Newton

• Galileo Galilei

What is Pangaea?

• A type of tectonic plate

• A supercontinent that existed millions of years ago

• A type of volcanic eruption

• A mountain range

Which of the following is a type of tectonic boundary?

• Erosional boundary

• Convergent boundary

• Sedimentary boundary

• Magnetic boundary

What happens at a convergent boundary?

• Tectonic plates move apart

• Tectonic plates slide past each other

• Tectonic plates move towards each other

• Tectonic plates remain stationary

The edges of plates are called (a)  

• convection

• boundaries

• subduction

Answer explanation

The edges of tectonic plates are referred to as boundaries. These boundaries are crucial in understanding geological processes such as earthquakes and volcanic activity, distinguishing them from terms like convection and subduction.

Which of the following is an effect of divergent boundaries?

• Formation of mountains

• Creation of new oceanic crust

• Earthquakes only

• Formation of deserts

Explain the significance of Alfred Wegener's contributions to geology.

• He discovered the structure of DNA.

• He proposed the theory of continental drift, suggesting continents were once connected.

• He invented the telescope.

• He developed the theory of relativity.

Describe the process that occurs at a divergent boundary.

• Plates move towards each other, causing mountain formation.

• Plates slide past each other, causing earthquakes.

• Plates move apart, allowing magma to rise and form new crust.

• Plates remain stationary, causing no geological activity.

How do transform boundaries differ from convergent and divergent boundaries?

• Transform boundaries involve the creation of new crust.

• Transform boundaries involve the destruction of crust.

• Transform boundaries involve plates sliding past each other without creating or destroying crust.

• Transform boundaries involve the formation of mountains.

Analyze the impact of convergent boundaries on Earth's surface.

• They create new oceanic crust.

• They cause the formation of mountain ranges and volcanic activity.

• They result in the formation of deserts.

• They lead to the creation of large lakes.
