What is Earth’s lithosphere made of?
Tectonic plates.
What causes tectonic plates to move?
The convection of the mantle.
How fast do tectonic plates move per year?
5 to 10 centimeters
Name one natural event caused by moving plates.
Earthquakes / Volcanoes / Mountains / Trenches
What are the three types of plate boundaries?
Transform (or conservative), convergent, and divergent.
What happens at a transform boundary?
Plates slide past each other.
What do convergent boundaries create?
Mountains / Trenches (e.g., Himalayas).
What did the African and Arabian Plates form?
The Red Sea.
What can you explore using a plate boundary map?
Earthquakes / Volcanoes / Earth’s landscape
What do we call the layer where plates float?
The mantle.
What happens at a divergent boundary?
Plates pull apart / move away.
Why do earthquakes happen at plate boundaries?
Because plates move and push/pull against each other.
