What type of rock is basalt primarily made of?

• Basalt
• Limestone
• Granite
• Sandstone

What layer beneath the lithosphere is described as a 'gooey' and 'plastic' layer?

• Asthenosphere
• Lithosphere
• Mantle
• Core

What process drives the motion of tectonic plates according to the video?

• Convection
• Radiation
• Conduction
• Subduction

What type of boundary occurs when tectonic plates slide past one another?

• Transform boundary
• Divergent boundary
• Subduction zone
• Convergent boundary

What geological activity is most commonly associated with divergent boundaries?

• Volcanic activity
• Tsunamis
• Earthquakes
• Landslides

What notable fault line is an example of a transform boundary?

• San Andreas Fault
• Mid-Atlantic Ridge
• Peru-Chile Trench
• Himalayan Fault

In convergent boundaries where oceanic crust meets continental crust, what geological feature is often formed?

• Volcanoes
• Deserts
• Mountains
• Plateaus

What is a hotspot in geological terms?

• A location where magma rises from the mantle to create a volcano
• A region of earthquakes
• A place where plates collide
• A tectonic plate boundary

What is typically found at convergent boundaries involving oceanic crust?

• Deep ocean trenches
• Rift valleys
• Mid-ocean ridges
• Plateaus

What is the significance of magnetic bands found in rocks at mid-ocean ridges?

• They provide evidence for sea-floor spreading
• They show volcanic activity
• They represent tectonic stability
• They indicate rock age
