Plate Tectonics starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plate Tectonics.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A tectonic plate moves at an average rate of 5 cm per year. How far will it move in 2 million years?
Describe how paleomagnetic evidence supports the theory of plate tectonics.
Describe the difference between oceanic and continental crust in terms of composition and density.
Describe the process that leads to the formation of a rift valley.
Describe what happens at a convergent plate boundary between an oceanic plate and a continental plate.
Explain how convection currents in the mantle contribute to the movement of tectonic plates.
Explain the process of sea-floor spreading.
Explain why earthquakes are common along plate boundaries.
Explain why the age of oceanic crust increases with distance from a mid-ocean ridge.
Name the three main types of plate boundaries.
The mid-ocean ridge is an example of which type of plate boundary?
