The cards Question What is the lithosphere? Tap to flip Answer The rigid outer layer of Earth, which includes the crust. Question What is the asthenosphere? Tap to flip Answer A semi-solid layer of Earth's upper mantle. Question Which is hotter: Earth's inner core or outer core? Tap to flip Answer The inner core. Question Which part of Earth's core is liquid? Tap to flip Answer The outer core; the inner core is solid. Question Why is Earth's inner core solid even though it is hotter than the outer core? Tap to flip Answer The pressure there is so great that it stops the rock from melting. Question What is a tectonic plate? Tap to flip Answer A large, rigid slab of the lithosphere that sits on the semi-solid asthenosphere. Question What is convection? Tap to flip Answer Heat transfer by moving fluids: warmer, less dense material rises and cooler, denser material sinks, making a circular flow. Question Name the two processes of gravitational sliding that contribute to plate movement. Tap to flip Answer Ridge-push and slab-pull. Question Do tectonic plates float on a sea of liquid magma? Tap to flip Answer No. The mantle beneath them is semi-solid. Question What is an earthquake's epicentre? Tap to flip Answer The point on Earth's surface directly above where the earthquake happens underground. Question What does an earthquake's magnitude measure? Tap to flip Answer The energy it releases. Question What is a plate margin? Tap to flip Answer The boundary where tectonic plates meet. Question What is a hotspot? Tap to flip Answer An area in Earth's mantle where unusually hot magma rises towards the surface, creating volcanic activity. Question With what does the global distribution of earthquakes and volcanoes coincide? Tap to flip Answer Plate margins. Question How do plates move at a constructive (divergent) margin? Tap to flip Answer Away from each other. Question What is a rift valley? Tap to flip Answer A long, narrow depression formed when a plate stretches and fractures at a constructive margin, so land sinks between parallel faults. Question What is a shield volcano? Tap to flip Answer A broad, gently sloping volcano formed by runny basaltic lava. Question Are shield volcano eruptions usually explosive or effusive? Tap to flip Answer Effusive: lava flows out. Question Do volcanoes occur only on land? Tap to flip Answer No. They also occur underwater, especially at constructive margins and hotspots. Question How do plates move at a destructive (convergent) margin? Tap to flip Answer Towards each other. Question What is subduction? Tap to flip Answer At a destructive margin, a denser oceanic plate sinking beneath a less dense plate into the mantle. Question What is a tsunami? Tap to flip Answer A series of large ocean waves caused by underwater earthquakes, volcanic eruptions or landslides. Question Why do volcanoes at a destructive margin form some distance from the margin itself? Tap to flip Answer The oceanic plate melts deep in the mantle, so magma rises to the surface away from the margin. Question How do plates move at a conservative margin? Tap to flip Answer They slide alongside each other. Question Why are there no volcanic eruptions at conservative plate margins? Tap to flip Answer No magma is produced there. Question What is magma? Tap to flip Answer Molten rock beneath Earth's surface. Question What is a primary impact of a tectonic hazard? Tap to flip Answer An immediate impact caused directly by the hazard. Question What is a secondary impact of a tectonic hazard? Tap to flip Answer An indirect effect that follows from the primary impacts, in the hours, days and weeks after. Question Why are the economic impacts of a volcanic eruption often highest in developed countries? Tap to flip Answer The property affected is of higher value. Question Are tsunamis and landslides primary or secondary impacts of an earthquake? Tap to flip Answer Secondary: they happen as an indirect result of the earthquake. Question How can an earthquake make a landslide more likely? Tap to flip Answer Ground shaking destabilises slopes. Question What is hazard risk? Tap to flip Answer The likelihood of being affected by a natural hazard such as an earthquake or volcanic eruption. Question In tectonic hazards, what is monitoring? Tap to flip Answer Techniques used to detect and record indicators of earthquakes and volcanic eruptions. Question Can scientists predict exactly when and where an earthquake will happen? Tap to flip Answer No. They can identify high-risk areas, but not the exact time, place or magnitude. Question Hazard management involves short-term relief and which long-term actions? Tap to flip Answer Planning, preparation and prediction. Question What is bathymetry? Tap to flip Answer The measurement of elevation for bodies of water, e.g. the depth of oceans, seas or lakes. Question What is topography? Tap to flip Answer The shape of Earth's surface, including land and the floor of seas and oceans. Question What does a GIS Elevation Profile show? Tap to flip Answer Changes in height above or below sea level along a transect line.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong.
